Levels Configuration Variables

MicroStation includes configuration variables to help set up all aspects of the level system.

The following table lists the configuration variables that affect Levels. Each configuration variable expects a valid value. An invalid value will not override a setting. You do not need to close and restart in order for the configuration variable change to take effect.

Variable Short name Description
MS_LEVEL_DISPLAY_FORMAT Level Display Format Specifies the formatting that the level name uses when the level lists display, including in PDF plots. If N, the default, the level name is used. If D, the level description is used; if C, the level code is used. More than one value can be specified.
MS_LEVEL_EDIT_NESTED_ATTACHMENT_LEVELS Edit Nested Attachment Levels If set, lets you edit the attributes of levels in nested reference attachments.
MS_LEVEL_ALLOW_LIBRARY_LEVEL_EDIT Edit Unused Library Levels Allows you to edit library levels when it is not yet used in master-file. If not set, then a library level can be edited only when if it is used. If set then a library level that is not yet copied into the master-file can be edited. On editing, the library level will be copied into the master-file.
MS_LEVEL_LOAD_ATTACHMENT_FILTERS Load Attachment Level Filters If defined, then level-filters of reference attachments are loaded.
MS_LEVEL_EDIT_ATTRIBUTE_LIST Control Level Attributes Edit Controls which level attributes can be edited or overridden (instead of using operating system privileges for the entire level library). The attributes to be edited can be one or more of the following as a comma separated list: Override Symbology (OverrideColor, OverrideStyle, OverrideWeight, OverrideMaterial), ByLevel Symbology (ByLevelColor, ByLevelStyle, ByLevelWeight, ByLevelMaterial), GlobalDisplay, GlobalFreeze, DisplayPriority, Transparency, Lock, and Plot. Each attribute accepts a "Library" or "Reference" prefix. Without the prefix, the attribute will be editable for both references and library levels.
MS_LEVEL_SYNC_ATTRIBUTE_LIST Control Level Attributes Synch Affects the DGNLIB UPDATE LEVELS CUSTOM and REFERENCE SYNCHRONIZE LEVELS CUSTOM key-ins. This variable controls the list of level attributes that will sync when any of the above key-ins is executed. The attributes can be one or more of the following as a comma separated list: OverrideSymbology, OverrideColor, OverrideStyle, OverrideWeight, OverrideMaterial, ByLevelSymbology, ByLevelColor, ByLevelStyle, ByLevelWeight, ByLevelMaterial, GlobalDisplay, GlobalFreeze, DisplayPriority, Transparency, Lock, and Plot. Each attribute accepts a "Library" or "Reference" prefix. Without the prefix, the attribute will be editable for both references and library levels.
MS_LEVEL_SYNCH_BYLEVEL Synch Symbology to ByLevel on Level Change If set, when you open a different model or view group, the active color, line style, and line weight are set to ByLevel.
The cases in which you open a different model or view group include:
  • opening a different file
  • opening the Models dialog and double-clicking a different model
  • exchanging a reference
  • selecting a different view group from the View Groups window
  • clicking the Previous Model or Next Model icons in the View Groups window
MS_LEVEL_AUTO_SYNC_ATTRIBUTE_LIST Level Attribute Auto Synch. This variable controls the list of level attributes that will automatically synchronize when a file is opened. The attributes can be one or more of the following as a comma separated list: OverrideSymbology, OverrideColor, OverrideStyle, OverrideWeight, OverrideMaterial, ByLevelSymbology, ByLevelColor, ByLevelStyle, ByLevelWeight, ByLevelMaterial, GlobalDisplay, GlobalFreeze, DisplayPriority, Transparency, Lock, and Plot. Each of the above attributes can take a "Reference" or "Library" prefix. If the prefix is not used, both reference and level library levels will be synchronized.
MS_LEVEL_DO_NOT_OVERRIDE_DESIGN_LEVELS_IN_SHEET Level Property Overrides in Sheet and Drawing Models Controls the overriding of design model level properties in sheet and drawing models. If set to 1, the level properties of a design model and its reference attachments cannot be overridden in a sheet or drawing model. They will be the same as when the design model is opened directly.
MS_LEVEL_SEED_LEVEL_NAME Seed Level Name Can be set to the name of a seed level. This can be a level in the master file, or a level in a DGNLib file. If the variable is not set, the default level is the seed level. When a new level is create, it takes the attributes of the seed level.
MS_LEVEL_CREATE_FROM_SEED_ATTRIBUTE_LIST Seed Level Attributes to use Controls the set of attributes of the seed level that are copied to the new level. Attributes can be one or more of the following attributes as a comma separated list: OverrideSymbology, OverrideColor, OverrideStyle, OverrideWeight, OverrideMaterial, ByLevelSymbology, ByLevelColor, ByLevelStyle, ByLevelWeight, ByLevelMaterial, GlobalDisplay, GlobalFreeze, DisplayPriority, Transparency, Lock, and Plot.
MS_UPDATE_KEEP_UNUSED_LIBRARY_LEVELS Keep Unused Library Levels If not set or set to 0, then unused library levels will be deleted when keying in DGNLIB UPDATE LEVELS. If set to 1, keying in DGNLIB UPDATE LEVELS will not delete all unused library levels. If set to 2, keying in DGNLIB UPDATE LEVELS will delete only unused library levels that are not synchronized with the open DGN file.
MS_LEVEL_PICKER_WIDTH Attributes Level Picker Width Sets the width, in pixels, of the level picker in the Attributes toolbox.
MS_REF_REATTACH_LEVEL_SYNC_ATTRIBUTE_LIST Ref. Reattach Level Attributes Specifies the list of level attributes that will sync 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, DisplayPriority, Transparency, and Plot.
MS_LEVEL_LIB_DIR Level Library Path Defines the default directory to look for when exporting levels or importing levels to/from a CSV, DGN, or DGNLib file.
MS_V7TOV8_CSVNAME V7 to V8 Level CSV File Defines the .csv file, which controls how levels are mapped when a V7 design file is upgraded to a V8 DGN file.
MS_V7_LEVEL_NAME_PREFIX V7 to V8 Level Name Prefix Defines the prefix to apply to unnamed levels when a V7 design file is upgraded to a V8 DGN file.
MS_V7TOV8_DELETE_UNUSED_LEVELS V7 to V8 Delete Unused Levels If set to 1, then all unused levels are deleted when a V7 design file is upgraded to a V8 DGN file. This variable is ignored if the V7 to V8 Level CSV File variable is set.
