Overview

Compressing a file using File > Compress Design or the related key-in commands (either by manual key-in or via batch process) makes these actions available:

Note that these actions are ignored by the 'Compress File on Exit' user preference, for details see: Compress File on Exit

Tick 'Include References' to initiate a batch process that will compress all attached references.

Note: this tick box has no effect in PowerDraft as the batch process features are not present.

File compress can be initiated manually via the dialog or by key-in.

Relevant key-ins include:

• COMPRESS DESIGN
• COMPRESS DESIGN INCLUDEREFS
• DELETE UNUSED
• COMPRESS OPTIONS (see How to turn ON/OFF Compress options via Key-in for more on this command, very useful when batch processing.)

Search MicroStation Help for details of these key-ins.

The File compress process will first apply any selected compress actions then will compact the file's structured storage removing any elements marked for deletion.

Configuration

These actions can be pre-set in the site configuration using the MS_COMPRESS_OPTIONS configuration variable. Adding the following:

MS_COMPRESS_OPTIONS   =  +ALL

would apply all available actions, the Compress Options dialog would appear as above.

Important: If using this variable with AECOsim Builiding Designer see:

Compress Options in AECOSim Building Designer - Behaviour and Configuration

Individual actions can be selected, as described by Ask Inga: Configure your compress options

The order of the statement is significant, +ALL ticks all the boxes (generally want all of them ticked), adding further entries prefixed by '-' can omit the stated compress actions where appropriate.
