Working with Units in Files That Will Be Saved to DWG
When saving a DGN file to DWG, the linear units in the resulting DWG file depend on a combination of:
- the Working Units, Master Units, Sub Units, and Accuracy settings in the Design File Settings dialog
- the Units setting on the Save As DWG/DXF Options dialog
Master Units | Sub Units | Accuracy | Units in Save As DWG/DXF Options |
Resulting Units in AutoCAD |
---|---|---|---|---|
Feet | Inches | Decimal | Master Units | Decimal/Engineering When using MU for the Format (Design File Settings dialog), if configuration variable MS_DWG_FEETUNIT_AS_ARCHENG is set, the resulting units are Engineering. If not set, the resulting units are Decimal. |
Feet | Inches | Decimal | Sub Units | Engineering |
Feet | Inches | Decimal | Inches | Engineering |
Feet | Inches | Decimal | Feet | Decimal |
Feet | Inches | Decimal | Any other | Decimal |
Feet | Inches | Fractional | Master Units | Architectural/Fractional When using MU for the Format (Design File Settings dialog), if configuration variable MS_DWG_FEETUNIT_AS_ARCHENG is set, the resulting units are Architectural. If not set, the resulting units are Fractional. |
