Modifying the Isometric Content

Isometric Content

To modify the isometric content, there are multiple options present in Isometric Configuration Tool. Using these options user can configure the content as per project requirement. In below section few of the important option has been discussed and shown with some examples. For details refer this article sub section which are consistently getting developed. 

North Direction

The north direction and label formats can be set for each Isometric Style. Use the steps below to set the north direction.

Open the Isometrics Configuration tool.
From the Isometric Configuration dialog:

1. Select the Isometrics Style tab
2. Style – Select the relevant style from the drop down.
3. Select Converter Settings from the Index.
4. Click Change to cycle through the direction options.
   
5. Click Save.

Coordinate Settings

The coordinate labels can be modified as required. This is also done in the Converter Settings section of the Isometric Style.

Label Formats – Specifies the annotation text to be used in coordinate labels
Misc. Converter Settings – This option will place allow below items to function based on selection ON/OFF. 

1. Place Diameter Labels - Determines whether pipe diameter labels are placed on isometric:
2. Place Diameter Change Labels - Determines whether a label is placed to mark a change in pipe diameter.
3. Fit To Page - Determines whether isometric uses the Fit to Page zoom option.
4. Minimum Pipe Length (mm) - Minimum permitted pipe length while showing Isometric drawing.  This value is expressed in (mm).

Slope Indications

A slope threshold value is set to determine what is treated as a slope and what is considered as a vertical offset. The value is entered in degrees. Any vertical offset that is equal or less to the value will be treated and annotated as a slope. Use the steps below to change the value.

Open the Isometrics Configuration tool.
From the Isometric Configuration dialog:

1. Select the Isometrics Style tab.
2. Style – Select the relevant style from the dropdown.
3. Select Dimensioning from the index.
4. Go to Slope tab.
5. Enter a value for Slope Threshold-Accuracy-text. See image below
   
   
   
   Note - Slope can be defined based on above option shown.
   
   
6. Click Save.
   
7. Generate Isometric & Verify results.

Skew Depiction

The Annotation Hatch section of the Isometric Style controls the triangle and hatch symbology for offsets. 

Open the Isometrics Configuration tool.
From the Isometric Configuration dialog:

1. Select the Isometrics Style tab.
2. strong>Style – Select the relevant style from the dropdown.
3. Select Rolling Offset dimension from the index.
4. Change the settings as required under Hatch Properties. 
   
   
   
   
5. Click Save.
   
6. Click on link on Triangle/Box Properties for details.

Spool Identifiers

The placement of pipe spool labels and the spool label definition can be specified in the User Labels configuration.

Turning On/Off

Use the following steps to turn off Pipe Spool Labels.

Open the Isometrics Configuration tool
From the Isometric Configuration dialog:

1. Select the Isometrics Style tabStyle – Select the relevant style from the dropdown.
2. Select User Labels from the index.
3. Disable the check box for Pipe Spool Labels.
4. Click Save.
   
    

Spool Label Definition

The following attributes define the setup of the spool labels:

Insulation

The configuration options for Insulation and Tracing are very similar. See below description.

Insulation

Open the Isometrics Configuration tool
From the Isometric Configuration dialog:

1. Select the Isometrics Style tab.
2. Style – Select the relevant style from the dropdown.
3. Select Insulation And Tracing from the index.
   Note - Tracing option has been added with new release. 
   
   
4. Change the settings as required.
5. Set the symbology as required.
   There are other options that has been added as mentioned below. 
   
   Show Insulation/Tracing - Determines whether Insulation/Tracing is displayed on the isometric.
   Show Double Insulation/Double Tracing - When checked, this option displays Insulation/Tracing on both sides of a fitting or pipe.
   Show Insulation/Tracing on Fittings - When checked, this option displays insulation (tracing) on both pipe and fittings. Otherwise either are displayed only on pipes.
   
   
6. Click Save.
   
   

Connection Label

Depending on whether the connected Pipeline has an Iso Sheet created for itself or not, two types of labels appear in Isometrics

To understand this concept lets assume,

• In OpenPlant Modeler, three Pipelines exist with names u-s-01-mEX-OPM, u-s-02-mEX-OPM and u-s-03-mEX-OPM
  
• A pipe in placed as a part of the pipeline u-s-01-mEX-OPM
  
• A pipe is created from the end of the previous pipe as a part of the pipeline u-s-02-mEX-OPM
• A pipe is placed from the end of the second pipe placed above as a part of the pipeline u-s-03-mEX-OPM
  
  
  
  
• In Pipeline Manager --> Iso Sheets are generated for Pipelines: u-s-01-mEX-OPM and u-s-02-mEX-OPM
  
  
  
• On generating the Isometrics for the pipeline u-s-02-mEX-OPM, the two ends of the pipeline displays the connection information in different formats.
  
  
  
  
• The Label in Red Box in the image is displayed when the Iso is connected to a pipeline whose Iso Sheets exists; here u-s-02-mEX-OPM is connected to pipeline u-s-01-mEX-OPM whose Iso Sheets exists.
  Lets take this as CASE A
• The Label in Yellow Box in the image is displayed when the Iso is connected to a pipeline whose Iso Sheet does not exist; here u-s-02-mEX-OPM is connected to u-s-03-mEX-OPM whose Iso Sheets does not exist
  Lets take this as CASE B
  
  

CASE A:

The Label that appears is -   'Cont. on : u-s-01-mEX-OPm-iso-1'
The label consists of three parts:
1> Cont. on

2> :

3> u-s-01-mEX-OPM-iso-1

The first part, i.e. the text "Cont. on' can be customized from OpenPlant Isometric Manager Tools --> Isometric Configuration--> Isometric Style --> Labels --> Connection Label --> Sheet Continuation

Change the value of Sheet Continuation as required; here it is Cont. on

The second part of the label can be customized from inside Bentley Class Editor.

• Launch Class Editor and open OpenPlant_3D.01.07 schema; supplement it with
  
  OpenPlant_3D_Supplemental_Information_3DComponent.01.07.ecschema.xml
  OpenPlant_3D_Supplemental_Isometrics_Isoextractor.01.07.ecschema.xml
  OpenPlant_3D_Supplemental_Modeling.01.07.ecschema.xml
  OpenPlant_3D_Supplemental_ModelingViews.01.07.ecschema.xml
• Go to Iso Sheet class as shown below
  
  
  
• Search for Continuation Expression in the class tab and customize the value as required; here it is : ( a colon) followed by a blank space
  
  
  
  

The third part can't be customized and is the name of the continuation Iso Sheet.

CASE B:

The Label that appears is-    'Conn. to :PIPELINE u-s-03-mEX-OPM'
Label consists of two parts.

1> Conn. to

2> : PIPELINE u-s-03-mEX-OPM

The first part, i.e. the text "Conn. to' can be customized from OpenPlant Isometric Manager Tools --> Isometric Configuration--> Isometric Style --> Labels --> Connection Label --> Connection Label

Change the value of Connection Label as required; here it is Conn. to

The second part of the label can be customized from inside Bentley Class Editor.

• Launch Class Editor and open OpenPlant_3D.01.07 schema; supplement it with
  
  OpenPlant_3D_Supplemental_Information_3DComponent.01.07.ecschema.xml
  OpenPlant_3D_Supplemental_Isometrics_Isoextractor.01.07.ecschema.xml
  OpenPlant_3D_Supplemental_Modeling.01.07.ecschema.xml
  OpenPlant_3D_Supplemental_ModelingViews.01.07.ecschema.xml
  
  
• Go to Classes -> Plant Base Object -> Named Item -> Pipeline; Search for Continuation Expression in class tab
  
  
• Change the Expression in Continuation Expression as per requirement; Here ":PIPELINE " & this.NAME
