I am trying to convert Archicad to a format that can be used to make heavy timber structural elements. when I use dwg files, they can read the file but the objects are not recognized as solids in Autocad for conversion to ACIS. I tried creating the 3D model in both open GL and with the internal 3D engine.</T></DIV> Thu, 05 Aug 2004 19:42:57 GMT https://community.graphisoft.com/t5/Collaboration-with-other/Converting-3D-files-to-ACIS-format/m-p/94242#M9286 Anonymous 2004-08-05T19:42:57Z https://community.graphisoft.com/t5/Collaboration-with-other/Converting-3D-files-to-ACIS-format/m-p/94243#M9287 ACIS Solids are in no way related to the geometry that is generated in ArchiCAD.
