DWG

DWG is Autodesk's native binary file format for AutoCAD. LinkCAD supports DWG import using the same engine as DXF, providing access to all geometry and layer data.

Format Summary

Property Value
Extensions .dwg
Encoding Binary
Import
Export
License Basic
Hierarchy Blocks with INSERT references
Layers Named layers with colors and properties

Note

DWG is import-only. To produce DWG-compatible output, export as DXF (which AutoCAD can open natively).

Import Options

DWG import shares the same options as DXF import:

  • Units & Scaling — physical units per DXF unit, scaling multiplier
  • Arc Resolution — precision for arc-to-polyline conversion
  • Entity Handling — text, HATCH processing, point import modes
  • Layer Options — BYBLOCK/BYLAYER attribute resolution

Supported Versions

  • AutoCAD R12 through AutoCAD 2018+

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.

CLI / Command-File Options

DWG import shares the same option keys as DXF import. Additionally, the following export keys apply when converting to DWG-compatible output via DXF:

Key Type Description
DwgOutUnitsUnit int Output units enum (see Units)
DwgOutUnitsValue int Output units scaling value
