MicroStation Functions in DWG Workmode

3D modeling

3D elements are placed only as ACIS bodies, and the Parasolid modeling engine is disabled. Because most of the 3D modeling tools work equally well with either kernel, this setting is transparent.

Annotating with flags

The Annotate tool box tools for placing and editing flags are disabled.

Area patterning

Area patterning is replaced by AutoCAD hatching. For details, see Patterning and Hatching.

Cells

Cells have the following limitations:

• Only shared cells are allowed. When you use library cells, they are placed as shared cells only.

• New cells must be created in cell libraries that are .DGN or .CEL files. You cannot create new cells in a .DWG file that is attached as a cell library.

For details, see Cells.

Colors

AutoCAD uses a standard color table for all files, rather than allowing custom color tables as in MicroStation. The colors used for displaying the DWG files in MicroStation match AutoCAD's display colors exactly. MicroStation and AutoCAD both use a slightly different set of colors for printing DWG files. For guidelines on modifying the color tables, see Colors.

Complex elements

Spline curves are not used as part of a complex chain or complex shape.

Design History

Design history is disabled.

Dimension-driven design

Dimension-driven design tools are disabled.

Dimensioning

Many MicroStation settings are not supported. For details, see Dimension Settings and Styles.

Element class

The active class is set to primary, and cannot be changed.

Grid orientation

The grid is aligned with a Top view so that it extends along the X and Y axes from the global origin.

Importing raster images

The Intergraph raster images, Sun raster, procedural application files, Georeferenced TIFF files, and Img files cannot be imported.

Line styles

Line styles  1-7 are disabled, and only custom line styles are allowed. For details, see Line Styles.

Models

DWG files allow only one design model and multiple sheet models.

For details, see Models.

Raster data handling

Some Raster Manager capabilities are not supported.

For details, see DWG Workmode.

References

The active model cannot be self-referenced. A reference cannot be clipped by mask. For details, see References.

Saved Views

The following are disabled:

• creating a saved view for sheet models

• applying a saved view to sheet models

• deleting a saved view from sheet models

• editing properties of a saved view for sheet models

Symbology

Element symbology overrides are disabled. All elements are displayed with ByLevel symbology (they use the attributes of the level).

Tags

Tags are attached only to shared cells. For details, see Tags.

Text fonts

*.SHX and TrueType fonts are supported. For details, see Text Styles and Fonts.

View Groups

View groups cannot be created, deleted, or modified.

View window background color

The Black Background -> White setting in the View Options category of the Preferences dialog box (Workspace > Preferences) is disabled. To change the display for models and layouts of DWG files, select the color in the DWG Open Options dialog box.
