Common Workflows
DWG → GDSII
Convert mechanical AutoCAD drawings to IC mask layout format.
DWG → DXF
Convert native binary DWG to the open DXF interchange format.
DWG → Gerber
Generate photoplotter data from AutoCAD mechanical designs.
GDSII → DWG
Export IC mask layout directly to native DWG format. Requires LinkCAD 11.
CLI / Command-File Options
DWG import shares the same option keys as DXF import. The following keys apply to DWG export (LinkCAD 11+):
| Key | Type | Description |
|---|---|---|
DwgOutUnitsUnit | int | Output units enum (see Units) |
DwgOutUnitsValue | int | Output units scaling value |
