DWG and DXF Files
NavisWorks's .dwg and .dxf file reader uses Autodesk's ObjectDBX technology and so is guaranteed to
read all object geometry and information for those third party applications that utilize the ObjectDBX
Framework.
The reader currently supports all surface (shaded) entities (3D faces, rectangular meshes, polyface
meshes, circles, extruded lines and so on), including Proxy Graphics and custom objects such as ACIS
based entities (3D Solid, Region), lines, points and snap points. Complex entities (shapes, dimensions,
text) are not supported. The structure of the drawing is preserved including xrefs, blocks, inserts,
AutoCAD color index, layers, views and active viewpoint. Entities are colored using the AutoCAD Color
Index (ACI), so will match those in an AutoCAD "shaded" view.
There is also an .nwc file exporter for AutoCAD - see AutoCAD .nwc Exporter for more details.
Note:
The reader supports files from all products based on AutoCAD 2009 and earlier.
