Coordinate Units
Master/Sub
Select Master or Sub to specify which of these units in the DGN 7 file
matches the default unit in the AutoCAD Map 3D map.
Each DGN 7 file defines a UOR (unit of resolution); in addition, it can define
Sub units and Master units. For example, if the default unit in your AutoCAD
Map 3D map is meters, and meters are the Sub unit in the imported file,
select Sub. If you select Sub or Master, the UORs in the DGN 7 file are
converted to Sub or Master units according to the conversion factor in the
DGN file header.
When you import the file, one Master or Sub unit (whichever you choose)
will become one drawing unit in your AutoCAD Map 3D map.
Unit Ratio
View the ratio between the Master and Sub units. For example, if the ratio
is 1:12 (as it would be for Feet/Inches), imported object coordinates will be
scaled 12 times bigger if you select Sub.
Element Expansion
Explode Multi Text
Explode multi-text objects into their component parts.
Create Text From Tags
Convert the contents of tags to text.
Explode Complex Chains
Return each component of a complex chain as its own feature (no feature
is returned for the complex chain as a whole). Otherwise, all elements of
the complex chain merge into a single linear feature, any arcs in the complex
chain become linestrings, and any linkages on the component elements
themselves are lost.
Cell Expansion
Create blocks From Cells
Expand cells into blocks, maintaining the cell grouping structure. This is
the default.
Explode Cells
Expand the contents of the DGN cells into their component parts. The
expansion is a single level deep. It does not expand all sublevels.
