Overview

This technical Document provides a description of the variables in MicroStation V8 (2004 Edition, V8.0 and V8.1)

This table lists the new variables available only in the MicroStation V8 2004 Edition. For other variables available in the MicroStation 2004 Edition as well as all variables available in MicroStation V8.0 and V8.1 see the second table on this page.

Configuration
_USTN_CAPABILITY _V7	Defines one or more capabilities in V7 workmode that are to be restricted. See MicroStation 's documentation for a full list of features and capabilities.
_USTN_CAPABILITY_DGN	Defines one or more capabilities in DGN workmode that are to be restricted.
_USTN_CAPABILITY	Defines one or more capabilities in MicroStation that are to be restricted.
Database
MS_ORACLEPREFETCH	Specifies the number of rows pre-fetched from the database, maximum 65535. For example if MS_ORACLEPREFETCH is set to 1000, there will be 1000 rows of data returned to the client and cached. If this configuration variable is not set, one row is pre-fetched. Setting MS_ORACLEPREFETCH can result in improved query performance over high latency networks, such as Wide Area Networks (WANs).
Data Files
MS_CUSTOMSHEETSIZEDEF	Defines the location of the sheetsizes definition file that can be used when creating sheet models.
MS_CUSTOMSCALEDEF	Defines the location of the scales definition file that can be used when creating models.
MS_REMAP_CSVFILE	If this configuration variable points to a remapping comma separated value (CSV) file, the remap filter defaults to that file for the remapping during the Save As operation.
Design History
MS_DESIGN_HISTORY_COMMIT_ON_SAVE	Specifies if the File>Save (^S) command should commit changes to design history. Possible values: 0 - Save command should save changes to the design file but should not commit changes to design history or prompt the user. The default is 0 (do not prompt or commit). 1 - Save command should prompt the user, offering the chance to commit changes to design history with a description. 2 - Save command should quietly commit changes to design history without prompting the user and without a description.
MS_DESIGN_HISTORY_COMMIT_ON_CLOSE	Specifies if changes should be committed to design history before closing the file. Possible values: 0 - Close command should save the changes to the design file but should not commit changes to design history or prompt the user. The default is 0 (do not prompt or commit). 1 - Close command should prompt the user, offering the chance to commit changes to design history with a description. 2 - Close command should quietly commit changes to design history without prompting the user and without a description.
MS_DESIGN_HISTORY_OWNERSHIP_WARNING	Specifies if the user should be prompted to confirm when opening a file that contains changes made by another user and not yet committed. Possible values: 0 - Open the file without prompting for confirmation The default is 1(prompt). 1 - Prompt for confirmation before opening the file.
MS_DESIGN_HISTORY_COLORS	The colors to use when identifying changed elements. The value must be a list of four color numbers, in the following order added, deleted, changed and pre-changed. Each color number must be a menu color index value. The default is: 2 4 1 3.
MS_DESIGN_HISTORY_REVISION_NUMBER_FORMAT	Specifies the how to display a revision number. The syntax is: formatClause := { [ "[" range "]" ] msgFormatPattern }+ range := start [,end] msgFormatPattern := string [ "{" msgFormatElement "}" string ]* msgFormatElement := argument [ "," elementFormat ] elementFormat := "number" \| "letter" [ "," letterStyle ] letterStyle := { "uppercase"\|"lowercase"\|"AA"\|"AB"\|{"omit" letter}* }+ The default is {0}.{1}
Dimensioning
MS_ANNOTATIONSCALEPROPAGATION	Will turn off the message box if the annotation scale is changed with the following settings: PROMPT (default) Will display the prompt dialog. ALWAYS Will make the change and not display the dialog. NEVER Will not make the change and will not display the dialog.
MS_NOTEAUTOUPDATE	Will control what will be propagated from the style if the style is changed. The following list will not be changed when the style is changed unless you set to "all" or set each of the below all separated by a comma. If not set the only way to change the note properties is with the Change Text tool. The default is off. ALL TEXTROTATIOM HORIZONTALATTACHMENT EDITABOUT HORICONTALJUSTIFICATION VERTICALLEFTATTACHMENT VERTICALRIGHTATTACHMENT
MS_DIMLEGACYPOINTORDER	If set to 1, the dimensioning tools will use the legacy datapoint sequence for placing linear and angular dimensions (ie., StartPoint - ExtensionPoint - EndPoint) instead of the current datapoint sequence (ie., StartPoint - EndPoint - ExtensionPoint).
DWG
MS_DWG_PRE2004_COLOR_TABLE	Sets the color table for DWG files in MicroStation. In version 2004, AutoCAD began displaying indexed colors with a slightly different (generally lighter) colors. MicroStation also uses these new colors unless this variable is set.
MS_DWG_CREATE_SEPERATE_SHEETS	If set, if a DGN contains sheet models, the sheet models are saved to separate DWG files with the file name created by appending the model name to the original file name. If not set, the sheets are saved to separate layouts within the DWG file.
MS_DWG_VPORT_LAYER_FROM_CLIP	Defines the viewport level in DWG files. Viewport entities are represented as reference attachments in MicroStation - the viewport level is extracted from the reference attachment. If no level is set for the reference attachment then by default the viewport is assigned to layer 0 . However, if this variable is set and a clip element is present, then the viewport layer is extracted from the clip element.
MS_DWG_VPORT_MAP_LOCATE_OFF_TO_LOCKED	If set, the Display locked status of a viewport entity is mapped to the Locate setting of the reference attachments that represent this viewport. In this case, a viewport with Display locked off will have Locate turned off - and changing the Locate status of the reference attachment will change the Display Locked status of the viewport.
MS_DWG_DISCARD_INVALID	If set, entities that are outside the DGN design plane are discarded and will not be written back to the DWG file on the next file save. If the variable is not set, MicroStation ignores these entities.
MS_DWG_LEADER_HOOKLINE	If set, an inline elbow is displayed on notes.MicroStation allows a note to be placed without an inline elbow (a hook line in AutoCAD) when the inline toggle is unchecked, but AutoCAD does not. This type of note (for instance, a leader without a hook line) saved to DWG will retain correct graphical presentation, and will operate properly in AutoCAD.
MS_DWGINSERTLAYER	Specifies the layer to which normal (unshared) cells and reference attachments are assigned when saving the open DGN file in DWG format. If this configuration variable is not defined, layer 0 is used.
MS_DWGOMITUNIQUEEXTENSION	If more than one file with the same name is present in the same directory, appends the extension to the output filename when saving the file.
MS_DWG_LSTYLE_FONTPATH	Determines the location for the font file.
MS_DWG_LSTYLE_FONTNAME	Determines the name of the font file (and therefore the name of the font).
Extensions
MS_FEATURE	Path to directory that contains MDL applications for Feature Modeling.
MS_MODELER	Path to directory that contains the MDL application MSMODELER which implements base functionality for Feature Modeling.
MS_DWG_OBJECT_APP	Lists Object Enabler MDL applications to be loaded. It is currently set to use applications that enable Architectural Desktop and AutoPlant objects (AdtDirectApp and RebisDirectapp). Users should not need to change this setting.
MS_DWG_PROXYSHOW	This variable controls the display of proxy objects within a DWG drawing. It is analogous to the AutoCAD registry setting "PROXYSHOW". Possible settings include 0 - no graphics, 1 - complete graphics and 2 - bounding box display only. The default setting is 1.
MS_DWG_LWDEFAULT	Controls the width of the default lineweight and is analogous to the AutoCAD registry variable "LWDEFAULT". The default value is 0 for unweighted default lines. valid LWDEFAULT values are 0, 5, 9, 13, 15, 18, 20, 25, 30, 35, 40, 50, 53, 60, 70, 90, 100, 106, 120, 140, 158, 200, 211.
MS_PROCESSEXCEPTIONLOG	: It is used too limit the number (and consequently the size) of the exception.log file.
File Saving
MS_V7AUTOSAVE	Determines the frequency, in seconds of the auto-save timer for V7 format files. For example, If set to 300 (the default), an auto-save will occur approximately 5 minutes after the first change to the design. The minimum value is 30 seconds.
MS_V7AUTOSAVE_NODIALOG	V7 format files take far longer than V8 format design files to save. Therefore, by default MicroStation displays a dialog box allowing the user to defer the auto-save operation. If this configuration variable is set, this dialog is skipped and auto-save occurs automatically.
MS_V7BACKUPV8	If this variable is set when working on a V7 DGN file, MicroStation will automatically create a backup file in V8 format every time you save. This provides a fallback in cases where you inadvertently create information that cannot be represented in the V7 format. This variable specifies a "template" that is used to create the backup filename. If you simply set the value to 'true', a file in the same directory as the original with the extension '.v8' is created.
MS_DWGAUTOSAVE	Determines the frequency, in second of the auto-save timer for DWG and DXF format files. For example, If set to 300 (the default), and auto-save will occur approximately 5 minutes after the first change to the design. The minimum value is 30 seconds.
MS_DWGAUTOSAVE_NODIALOG	DWG and DXF format files take far longer than V8 format design files to save. Therefore, by default MicroStation displays a dialog box allowing the user to defer the auto-save operation. If the configuration variable is set, this dialog is skipped and the auto-save occurs automatically.
Levels
MS_MERGE_DISPLAYEDLEVELSONLY	When set, only the displayed levels will be merged when saving to V8 or DWG.
MS_LEVEL_EDIT_ATTRIBUTE_LIST	This variable controls the list of reference or library level-attributes that can be edited The attributes can be one or more of the following as a comma separated list : OverrideSymbology, OverrideColor, OverrideStyle, OverrideWeight, ByLevelSymbology, ByLevelColor, ByLevelStyle, ByLevelWeight, GlobalDisplay, GlobalFreeze, Lock, Plot. Each of the above attributes can take a "Reference" or "Library" prefix. Without the prefix, the said attribute will be editable for both reference & library levels.
See ** below	When set to 1, reference attachment levels will not synchronize to an attached library.
MS_HIDE_LIBRARY_SOURCE_NAMES	(this variable must be created) Hides the Level library name that is in brackets that proceeds the level name if set to 1.
MS_LEVEL_EDIT_NESTED_ATTACHMENT_LEVELS	If defined, then allow editing of nested attachment levels.
MS_LEVEL_SEED_LEVEL_NAME	If defined, then name of seed level. A new level inherits its properties from the seed level. If not defined, then the default level is the seed level.
MS_LEVEL_LOAD_ATTACHMENT_FILTERS	If defined, then level-filers of reference attachment is loaded.
MS_LEVEL_CREATE_FROM_SEED_ATTRIBUTE_LIST	This variable controls the list of level attributes that are copied from the seed level. (Ms_Level_Create_From_Seed_Attribute_List). The attributes can be one or more of the following as a comma separated list: OverrideSymbology, OverrideColor, OverrideStyle, OverrideWeight, ByLevelSymbology, ByLevelColor, ByLevelStyle, ByLevelWeight, GlobalDisplay, GlobalFreese, Lock, Plot.
MS_LEVEL_AUTO_SYNC_ATTRIBUTE_LIST	This variable controls the list of level-attributes that will automatically synchronized when a file is opened. The attributes can be one or more of the following as a comma separated list: OverrideSymbology, OverrideColor, OverrideStyle, OverrideWeight, ByLevelSymbology, ByLevelColor, ByLevelStyle, ByLevelWeight, GlobalDisplay, GlobalFreeze, Lock, Plot. Each of the above attributes can take a "Reference" or "Library" prefix. Without the prefix, the said attribute will be synchronized for both Reference and Library levels.
Operation
MS_NATIVEMAINMENU	If set to "0", menus that are larger than the screen size no longer function as they did in MicroStation/J. Top and bottom scroll arrows no longer appear and auto menu positioning no longer functions. If set to "1", Menus will appear correctly.
MS_MAINMENUDOCKINGBESIDE	If set to a non-zero value, tool boxes and dockable dialogs may be docked alongside the main menu bar. If not set (default) or set to 0, MicroStation's main menu bar spans the entire width of the application window.
MS_IDLETIMEOUT	If defined, specifies the number of minutes of inactivity to wait before exiting MicroStation. Minimum value is 30 minutes. A value of 0 means never exit, even when idle.
MS_COMPRESS_OPTIONS	Set the values for individual items by alias. To turn an item on, precede the alias with a +. To turn an item off, precede the alias with a -. For example, +FONTS;-LEVELS will will delete unused fonts but leave unused levels. The special aliases ALL and DEFAULT can be used here. +DEFAULT means that any items not in the list should default to on; -DEFAULT means that any items not in this list should default to off. If this variable is set, it will override user preferences.
MS_POPUPDIALOGCLOSEDELAY	Specifies the amount of time to wait before closing a popup dialog (Eg. the dialogs launched from the Primary toolbox).The value, specified in 1/60 second increments, should be a number between 0 (very little delay) and 120 (2 seconds).The default is 30 (1/2 second).
MS_FULLPATHINTITLEBAR	When turned on, the full path of the current Design File is displayed in the main title bar.
Primary Search Paths
RDL_DIR	Defines the location and/or extension of the Bentley Redline generated redline file that the Redline On tool searches for. Defaults to <ActiveFileName>.rdl in the same directory as the active DGN file.
DWGRDL_DIR	Defines that location and/or file name appendage of the Bentley Redline generated DWG redline file that the Redline On tool searches for. Defaults to <ActiveFileName>_redline.dwg in the same directory as the active DWG file.
Print/Plot
MS_PLOTBORDER_TIME_FORMAT	Changes the date and time format for printed outputs from Windows Regional Settings to another format. Set to v7.0 to use the v7.0 format.
MS_PLT_NORASTERTRANSPARENCY	If defined, disables raster transparency settings when generating print files with drivers that do not support transparency (mainly postscript drivers). This prevents inflating the size of printed output, thus improving printing speeds.
MS_PLTMODELNAME	Displays the name of the model from which the print is produced.
MS_PLOTDLG_DEF_PLTFILE	If this variable is to a printer driver (.plt) filename, that printer driver will be loaded (instead of the last used printer driver) when you open the print dialog box.
MS_PLT_SYSPRT_PLTFILE	If this variable is set to a fully-qualified print driver (.plt) filename, then this will be used instead of Printer.plt when Windows Printer is selected in the print dialog box.
MS_PLT_SYSPRT_DEFAULT_PRINTER	Allows you to specify the printer name that is selected when a default system printer is opened.
MS_PLT_SYSPRT_DEFAULT_FORM	Allows you to specify the form name that is selected when a default system printer is opened.
MS_PLT_SYSPRT_DEFAULT_TRAY	Allows you to specify the tray name that is selected when a default system printer is opened.
MS_PLTFILES	Default output directory for plot files, if the most recently used directory is not defined.
MS_PLTDLG_FORCEOUTDIR	May be used to specify the output directory for plot files, if not specified in the .plt file or on the key-in command. This variable takes precedence over the most-recently-used directory stored in the user preference file.
MS_BATCHPRINT_LOGFILE	Used to set the name of the batch printing log file.
MS_BATCHPRINT_ADD_ONLY_SHEET_MODELS	If set to 1, Batch print will only add sheet models to the job set when the design file is added. The Default is 0.
MS_BATCHPRINT_ADD_ALL_MODELS	if set to 0, Batch print will not add multiple entries, one per model, to the job set when the design file is added. The default is 1.
MS_BATCHPRINT_SETUPSYSPRT	Can be used to control the behavior of the Batch Print Setup System Printer Dialog. The following values are recognized. PRNSELECT; (default) the icon invokes the Windows printer selection dialog. PAGESETUP; the icon invokes the Windows page setup dialog.
MS_PLT_USE_MRU_DEFAULTS	The variable is a convenient way to disable use of most-recently-used default files and directories throughout the plotting system. Normally, MRU locations are used instead of configuration variables when Open or Save dialogs are presented. If this variable is set to '0' the configuration variable will always be used instead.
MS_PLTDLG_ENABLE_ORIENTATION	The orientation control on the print dialog allows you to quickly reverse the X&Y values of the paper size record without having to edit the .plt file. This is necessary for printer.plt and helpful for some Postscript-to-PDF workflows, but not desirable for most HP/GL2 and HP/RTL workflows. To reduce confusion and prevent any accidental swapping of the X&Y sizes, the orientation control is disabled by default for Bentley Printer drivers. You may control this behavior by using the variable. Valid values are: 0 orientation is always disabled for Bentley drivers (default) 1 orientation is always enabled for Bentley drivers. NOTE: This variable does not apply to system printers.
MS_PLTDLG_PREVIEW_ORIENTATION	By default, MicroStation displays the preview window with the same orientation as the design, regardless of the orientation of the paper size definition. This prevents you from having to twist your head when previewing landscape designs maximized to portrait-oriented forms. You can use MS_PLTDLG_PREVIEW_ORIENTATION to change this behavior, as may be desired when working with portrait designs and landscape forms. Recognized values are: DESIGN: the preview will use the orientation of the design (default behavior). PAPER: the preview will use the orientation of the paper size definition. LANDSCAPE: the preview use landscape orientation. PORTRAIT: the preview use portrait orientation. Note that if the preview is displayed in a different orientation than that indicated by the orientation radio button, then the preview display of 'rotate 90' will be reversed as well. This variable does not apply to system printers.
MS_PLT_PREVIEW_USABLEAREACOLOR	specifies the color of the usable area rectangle in the preview window. If zero, the rectangle is not drawn. For legal values, see the description for MS_PENTABLE_DISABLECOLOR.
MS_PLT_PREVIEW_PRINTABLEAREACOLOR	Specifies the color of the printer driver's printable area rectangle in the preview window. If zero, the rectangle is not drawn. For legal values, see the description for MS_PENTABLE_DISABLECOLOR.
MS_PLT_PREVIEW_PLOTBOXCOLOR	Specifies the color of the print bounding box rectangle in the preview window. If zero, the rectangle is not drawn. For legal values, see the description for MS_PENTABLE_DISABLECOLOR.
MS_PLT_PREVIEW_PLOTFENCECOLOR	Specifies the color of the print fence shape in the preview window. If zero, the shape is not drawn. For legal values, see the description for MS_PENTABLE_DISABLECOLOR.
MS_PLT_ENABLE_SCALE_CLIPPING	If it is set to 0, the plot dialog does not reduce the plot fence or sheet size in order to accommodate the user-or-sheet-specified scale factor.
MS_PLT_ENABLE_AUTO_ROTATE	If it is set to 0, the print dialog does not automatically change the plot rotation in order to achieve a best fit. This variable only applies to Bentley plotter drivers.
MS_PLT_ENABLE_PRESERVE_SCALE	If it is set to 0, the plot dialog does not attempt to preserve the current plot scale when a new view, fence, or paper size is selected.
MS_PLT_ENABLE_AUTO_ORIENT	If it is set to 0, the print dialog does not automatically change the paper orientation in order to achieve a best fit. This variable only applies to system printers.
MS_PLT_HONOR_SHEET_INFO	The variable can be used to prevent the plot dialog from applying sheet attributes stored in the model when it creates a plot description. Normally, if sheet attributes are present, the plot will default to PlotArea=Sheet and the plot boundary is set automatically from the sheet. If this variable is set to 0, the print dialog acts as if there are no sheet attributes present.
MS_PLT_AREA_PRIORITY	If it is set to 1, sheet definitions in the model take priority over the active fence. New fences are ignored when the print area mode is sheet. This is the default setting. If this variable is set to 2, the active fence takes priority over sheet definitions.
MS_PLT_FORM_SCALE_PRIORITY	If it is set to 1, the default form scale specified in the .plt file is re-applied whenever the paper size changes. By default, the current print scale is preserved.
MS_PLT_MAX_ON_NEW_AREA	If it is set to 1, the print size is automatically maximized when the print area is changed. This includes when a view number is selected or a fence is placed. By default, the current print scale is preserved.
MS_PLT_FIT_RASTER_REFS	If it is set to 1, the print dialog includes raster references when computing the design range for the Fit print area modes. By default, it does not.
MS_PLT_AUTO_FIT_VIEW	If it is set to 1 or 2, the print dialog automatically sets the print area mode to Fit Master or Fit All respectively when first invoked (and a fence or sheet is not defined). Otherwise, the print area mode is set to View.
MS_PLTDLG_KEEPVIEWFLAGSONFENCECHANGE	When a new fence is placed, the print dialog obtains new view information from the view the fence was placed in, and resets the print attributes if the new fence view is different than the current print view. However, if MS_PLTDLG_KEEPVIEWFLAGSONFENCECHANGE is set, the print dialog will always preserve current print attributes.
MS_PLTDLG_WEIGHTOVERRIDE	Can be used to set the print dialog's weight print attribute automatically to a value other than the one obtained from the view. This is may be desirable when plotting DWG files (which typically do not have weights turned on) with pen tables. The override is applied whenever print dialog settings are obtained from the view. The following values are honored: 0: weight override is set; the print weight attribute is turned off regardless of the view setting. 1: weight override is set; the print weight attribute is turned on regardless of the view setting. VIEW: weight override is not set; the print weight attribute is obtained from the view setting. PENTABLE: weight override is conditionally set; the print weight attribute is turned on if a pen table is attached that contains output width specifications. Otherwise, the attribute setting is obtained from the view. This is the default value when the variable is not defined.
MS_PLOTDLG_DEF_PENTABLE	Defines a default pen table that is loaded when you open the Print dialog box.
MS_PLTDLG_SETUPSYSPRTICON	Can be used to control the behavior of the 'Configure Windows Printer' icon on the print dialog. The following values are recognized: PRNSELECT: (default) the icon invokes the Windows printer selection dialog. PAGESETUP: the icon invokes the Windows page setup dialog.
MS_PLT_ENABLE_PAGESETUP_MARGINS	If it is defined, the margins are enabled on the Windows Page Setup dialog. By default, the margins are disabled. This variable only applies to system printers not in fullsheet mode.
MS_PLTDLG_SETUPSYSPRT_ENABLE_PRINT	Can be used to control the print behavior of the "Configure Windows Printer" icon on the print dialog. By default, the print button on the Windows Print dialog in this mode saves printer driver changes without submitting a plot. If this variable is set to 1, the print button will submit a plot (original MicroStation V8 behavior).
MS_PLTDLG_ENABLE_SAVE_CONFIG	If it is set to 0, the print dialog save configuration menu items are disabled.
MS_PLT_SCALE_METHOD	Determines how the print scale is displayed in the print dialog. This variable overrides the corresponding user preference. The following values are recognized: 1: the scale display is paper-to-design format (default). 2: the scale display is design-to-paper format. If this variable is not defined, the user preference controls the scale method. This variable also controls the appearance of MS_PLTSCALE_SHORT.
MS_PENTABLE_IMPORTEMPTYSECTIONS	By default, during AutoCAD plot style table import, pen table sections which have no effect (the settings are default) are ignored. Setting this variable to 1 will cause empty sections to be created.
MS_PENTABLE_DISABLECOLOR	A disabled section in a pentable is shown in medium gray by default. You can modify the disabled color by setting this configuration variable to one of these numbers: blue=1; red=4; magenta=5; light-gray=8; medium-gray=10; turquoise=13; dark-green=14; maroon=15; dark-yellow=17.
MS_PENTABLE_REGEX_LEVEL_COMPARE	If is defined, regular expressions will be evaluated when comparing level names in the pen table.
MS_PENTABLE_SLOTNUM_MATCH_APPLIES_TO_CHILD	By default, a pen table reference slot number match applies to both a parent reference and its children. If MS_PENTABLE_SLOTNUM_MATCH_APPLIES_TO_CHILD is set to 0, then the slot number match applies only to the parent reference.
MS_PENTABLE_IMPORTCTB_NOPENMAP	By default, the pen table creates printer driver pen maps when importing CTB files. This permits proper color-to-width resymbolization of multi-colored elements. The legacy, element-output-action-based behavior may be restored by setting the MS_PENTABLE_IMPORTCTB_NOPENMAP configuration variable.
MS_PLTFILE_EDITOR	Fully qualified name of a text editor to use for when File > Edit Printer Driver on the Plotdlg menu is activated. Setting this variable to HIDE_MENU_ITEM will prevent the File > Edit Printer Driver and the File > Reload Printer Driver menu items from being shown.
MS_PLNONAME	If set, the RTL/PCL drivers will not insert the DGN name in the output file. Adding the DGN name should allow a printer to display the name in its front panel window, etc. but setting this variable will allow the feature to be disabled, since some printers cannot handle it.
MS_PLT_VIEWFLAGOFF_LINEWIDTHMM	When the view flags have line weights turned off, all lines are drawn with the thinnest line available. However, as printer DPI has increased over the years, the thinnest line is getting too thin. Setting this variable allows you to set minimum line thickness in millimeters.
MS_PLT_INVERT_WHITE_COLORS	The variable allows you to override the colors that are automatically inverted from white to black if necessary. If this variable is not defined, the default inverted color numbers are 0 and/or 7, depending on the drawing file format and color table. The syntax for this value is the same as a level number list, with range 0-254.
MS_PLT_OLE_MAX_MFB_SIZE	When plotting OLE objects to non-system printers, MicroStation must render the object at device resolution into a memory frame buffer (MFB). By default, the MFB is limited to 4096 pixels in both width and height. This is approx.. 13x13" at 300 dpi, and consumes 48MB. If the paper size of the object is larger than 4096 dots, the MFB is scaled accordingly. That can reduce the sharpness of the image. For sharper plotted OLE objects at the expense of memory usage, processing time, and plot file size, you may set MS_PLT_OLE_MAX_MFB_SIZE. The valid range is 1024 through 16384 (units are pixels). This variable does not apply to system printers.
MS_PLT_FORCE_HARDWARE_TEXT	If it is set to 1, some text that otherwise would be stroked in software is sent to the printer driver as hardware text. These conditions include rotated, slanted, mirrored, and vertical text. Note that it is likely the text will not be output correctly in these cases. Therefore, this variable should only be set if the text representation is more important than the text display.
Protection
MS_PROTECTION_LICENSE_ENABLE	Set to 0 to disable license creation. Set to 1 to enable password licenses. Set to 2 to enable certificate licenses. Set to 4 to enable Everyone Licenses. Set to 7 to enable all types of licenses. The default is 7 (all types of licenses).
Reference
MS_REF_DEFAULTATTACHDIRECTORY	If this variable is set, the reference attachment dialog defaults to this directory, rather then the directory of last attached reference.
MS_REF_DEFAULTSETTINGS	This variable controls the default settings for reference attachments. It is set to a comma separated list of key=value pairs, for example: snap=1, locate=0, truescale=1, scalelinestyles=0, Recognized keys and values include display=0\|1, snap=0\|1, locate=0\|1, useLights=0\|1, saverelativepath=0\|1, scalelinestyle=0\|1, ignorewhennesting=0\|1, displayrasterrefs=0\|1, displayboundary=0\|1, nestmode=livecopynest, nestDepth=value, attachmethod=coincidentworld.
MS_REF_REATTACH_LEVEL_SYNC_ATTRIBUTE_LIST	This variable controls the list of level-attributes that will synchronize when a reference is reattached. The attributes can be one or more of the following as a comma separated list: OverrideSymbology, OverrideColor, OverrideStyle, OverrideWeight, ByLevelSymbology, ByLevelColor, ByLevelStyle, ByLevelWeight, GlobalDisplay, GlobalFreeze, Lock, Plot
MS_DISALLOWFULLREFPATH	When set to 1, MicroStation does not save the full path to references. By default, MicroStation stores both an abbreviated (portable) path and the full path to references. The full path will be wrong if the directory structure for a project is changed or if a different file server drive letter is used, so it can cause inconsistent reference file location in those situations. Therefore, some sites prefer that the full path not be saved. (MS_DISALLOWFULLREFPATH)
MS_REF_NEWLEVELDISPLAY	When set to 1, MicroStation displays newly created levels in references. By default, when new levels are created in a model that is referenced by another model, the new levels are not displayed when the referencing model is opened. Newly created levels are considered to be new until "Save settings" is performed. Recognizing new levels and controlling their display is only possible when using the MicroStation V8 file format for both the reference and the master file.
MS_NEST_COLORADJUSTMENT	If not set, the color adjustment for the top level reference controls the color adjustment for all nested references. When set to any value, nested reference color adjustments at each level are multiplied to get the net adjustment. For example, with C attached to B with a saturation adjustment of 80%, and B attached to A with a saturation adjustment of 70%, C will display in A with a saturation adjustment of 56% if MS_NEST_COLORADJUSTMENT is defined, and with saturation adjustment of 70% if it is not.
MS_REF_DONTHILITEFORMANIP	By default, MicroStation hilites all elements in a reference file when the reference is manipulated (move, rotate, scale, etc.) If MS_REF_DONTHILITEFORMANIP is set to any value, this hiliting is disabled. This can speed up reference manipulations, but it is more difficult to tell which references are getting manipulated.
Rendering/Image
MS_IMAGE_EDITOR	Default program to be used to edit an image file. This program is activated by double-clicking in the preview area of the Map Editor dialog.
MS_MATERIAL_PREVIEW_BACKGROUND	Image to be used for the background of material previews in the Material Editor.
MS_RENDERV7MATERIALS	If set to 1, materials are rendered as they were in V7. Most affected are translucency, transparency, specularity, and diffuse as applied to pattern maps.
Security
MS_SECURITY_LEVEL	This is the security level for loading and running application in MicroStation. Set to NONE to disable security checking. Set to LOW to allow any MDL or other applications to be loaded and used. Set to MEDIUM to allow only applications that are digitally signed by Bentley or by a certificate identified by MS_SECURTIY_SPC. Set to HIGH to allow only applications signed by Bentley. The default is NONE.
MS_SECURITY_SPC	This is the path where MicroStation can find the Software Publishing Certificates that were used to digitally sign the applications that can be loaded in MEDIUM security level. The default is null.
Standards Checker
MS_STANDARDSCHECKER_SETTINGSFILE	If this variable is set, the specified file is always is always used for Standards checking.

This provides a fallback in cases where you inadvertently create information that cannot be represented in the V7 format. This variable specifies a "template" that is used to create the backup filename. If you simply set the value to 'true', a file in the same directory as the original with the extension '.v8' is created.
MS_DWGAUTOSAVE	Determines the frequency, in second of the auto-save timer for DWG and DXF format files. For example, If set to 300 (the default), and auto-save will occur approximately 5 minutes after the first change to the design. The minimum value is 30 seconds.

MS_PLTDLG_UNLOADONCLOSE	Controls whether the print dialog is unloaded when its window is closed. If "1" or undefined, the print dialog application unloads itself when its dialog is closed, and all settings revert to their defaults when the dialog is reopened. If this variable is set to "0", the application remains loaded after the window is closed, and certain settings are retained when the print dialog is reopened. For consistent behavior of the print dialog, it's recommended that this variable be undefined. Note that selecting File > Exit from the print dialog menu always unloads the application.
