Hi all, Does anyone know the best way to import dwg of r13? I used ACAD r13 to export drawing to 3d studio4c1. However, some of the surface of solid were missing. for example, a box would only show 4 faces. Please help! Thank you

In short, you will have much more control with DXF export and import. 3DSOUT is required to export ACIS/Region models and light, cmaera, & material setups. For the complete answer, check out chapter 11 of "Inside 3DS R4" – Phil

Thank you for the suggestions. I have tried to export with DXF, but all the drawing created with solid modeling disappeared. I wonder DXF doesn't support the solid modeling yet. Ken

By solid modelling I assume you mean R13 ACIS entities correct? These are encrypted within the DXF format and not capable of being read without a liscence agreement. Thus 3DSOUT is your only method. If you're exporting AME/Designer/AutoSurf models, then you have to create a mesh representation prior to DXF export. – Phil

Ken Using the 3DSOUT command from AutoCAD, you need to adjust the FACETRES variable before exporting the file. That will generate smoother curves. However make sure you are using C3 of AutoCAD. I was having all kinds of problems with 3DSOUT until I got to C3 of AutoCAD Hope this helps Steve

>> a box would only show 4 faces. << This pertains to "normals" — the direction that the face is pointing. A quick fix is to apply a 2-sided material. Otherwise, you can Surface/Normals/(4 options) to flip or unify your normals manually. – Dave
