DXF Export for SpaceClaim is an AutoCAD DXF file export add-in for SpaceClaimÃ??Ã?Â®. This add-in gives SpaceClaim the ability to export 3D solid data from a SpaceClaim part and assembly document to 3d solids in an AutoCAD DXF file. SpaceClaim already has the ability to export AutoCAD DXF files. However the DXF export feature ignores solids and surfaces and only exports curves, thus making the DXF file practically useless for 3D modeling in AutoCAD or other programs that can read solids from DXF files. DXF Export for SpaceClaim removes this limitation by giving SpaceClaim the ability to export solids to AutoCAD DXF files.
