Summary0000151: support 3DFACES in dxf import & export
DescriptionDXF format, althought it is "open", is very closed inrelation with 3D. There are basically 2 possible types of 3D data in a dxf file: 3DFACE entities, which are simple triangles, and ACIS data, which comes as one big block of binary code inside the file. ACIS format is proprietary and undocumented, so its a no-go for us... But it supports solids and all the stuff.

Supporting 3DFACE entities is actually not too useful, but it will at least allow to export something.
TagsNo tags attached.

added in r4330. 3DFACE entities, 3D polyline meshes and 3D polyface meshes (both special kinds of polylines) are imported respectively as Part faces and meshes.
I also added an option in the Draft preferences to allow exporting 3D objects as polyfaces, therefore allowing for more or less decent dxf 3d export.
