Sets how IGES file units are equated to MicroStation working units, as follows:
Sets how subfigures are translated, as follows:
In IGES, subfigure (type 308) or network subfigure (type 320) entities are used to store a group of entities that occur repetitively within a file, performing about the same function as MicroStation cells. |
Sets how IGES drawing entities and entities with views visible attributes are translated:
Merging drawing information is usually less efficient since entities are repeated for each view rather than being created just once and referenced in sheet DGN files. Merged drawing entities are omitted from a view(s) based on their view visibility, and their symbology is set to the appropriate symbology for each view.
Sheet DGN files are created with the same filename as the model DGN file with the extension “.Sxx,” where “xx” is the drawing sheet number. For example, the first sheet DGN file for “test.dgn” would be “test.s01,” the second “test.s02,” and so on. If the MS_SHEETSEED configuration variable is set, the sheet DGN file is created from the seed file it points to. Otherwise, the sheet DGN file is created by copying the header data from the model DGN file. |
See Drawing sheets and view visibility for general information about drawing sheets and view visibility. |
Sets the scale factor that is applied to imported IGES entities; can be used to tailor the translation to accept geometry from systems that generate data at a different scale or in a different coordinate system.
By default, the scale factor is set to 1.0 (no scaling is performed).
Sets the maximum deviation, in Translation Units, between the actual curve and the approximating line segments used to represent excluded arc, curve, B-spline curve, or B-spline surface entities in the DGN file.
If any of these IGES entities are excluded in the Exclude IGES Entities dialog box (opened by choosing Settings > Exclude IGES Entities in the Import IGES File dialog box), they are approximated by line segments, referred to as strokes, in line string or shape elements.

Sets the IGES line weight (thickness) in millimeters (mm) that is assigned to MicroStation line weight 31. The other MicroStation line weights are assigned thicknesses that are proportional to this value.
An inverse relationship exists between the Maximum Line Width and the MicroStation line weight that is assigned to a line from the IGES file. Consider a line in an IGES file that has a thickness of 2.5 mm:
If Maximum Line Width is set to 5 mm (the default, about 0.2"), the line is assigned to MicroStation line weight 15.
If Maximum Line Width is set to 10 mm, the line is assigned to MicroStation line weight 7.
Thus, increasing the Maximum Line Width setting decreases the MicroStation line weight assigned to a given line.
IGES line weights are associated by the actual line thickness. MicroStation Line Weight is not associated with a specific thickness, but instead determines the relative line weight of a line with respect to other line weight values. |
If on, the IGES file is assumed to be VDAIS-compliant.
see footnote 161
If on, imports IGES entities which are marked as construction or blanked entities.
