Inport Options
Insert polyface mesh, 3DFace and Solid entities into 3D as Select how you want to import these entities as 3D into SpaceClaim.
Insert polyface mesh, 3DFace and Solid entities onto drawing sheets as Select how you want to import these entities onto drawings sheets.
Insert hatch entities as Select the behavior for hatch identities.
Center imported data This is useful for AutoCAD files that have models positioned outside of the SpaceClaim modeling range (+/- 1km). The center of the bounding box for the imported data is moved to world origin coordinates (0, 0, 0). This option is ON by default.
Allow default code page conversion This setting must be on in order to support text entities and table names that require a code page conversion. The latest version of Teigha has removed the need for this but the current version of RealDWG still needs it.

Substitute font Select a font to use when the original font in the DXF file is missing.
Teigha (Associated Dimensions) to use Teigha 2021.7 libraries.
Autodesk RealDWG to use Autodesk RealDWG libraries (up to 2021). Import supports associated dimensions in your design. Use this option to import DWG files with 3D bodies. For export it will disconnect dimensions from the geometry in your design.
