DWG Converter

Overview

DWG_Reader can read files compliant with the DWG formats AutoCAD 2013 - AutoCAD 2017 (AC1027) and AutoCAD 2018 (AC1032).

Mapping

Import Mapping

Table below shows how DWG entities are mapped into CAD Exchanger entities after import.

DWG Entity CAD Exchanger Entity
Block Header ModelData_Assembly
Insert ModelData_Instance
3DSolid, 3DFace, Polyline Mesh, SubDMesh, Polyline PFace ModelData_Part

DWG file may contain multiple geometries inside one "Block Header" entity, in that case all entities will be mapped to single ModelData_Part.

Scope

  • polygonal representations
  • B-Rep representations (stored in ACIS sections)
  • colors and materials
  • assembly structure
  • names

Known Limitations

DWG file may contain only BRep geometry, only mesh geometry, or both. When mixed geometry is used, CAD Exchanger converts it all to BRep, since mixed part definitions can't be represented in ModelData_Model.
