I'm trying to take models created in a cad program (Unigraphics) and then import them into Blender for further editing. The common file format is DXF which Unigraphics can export. However, when I try to import a dxf file into Blender, there are a lot of holes in the model where faces should be.
There is a very simple dxf file at http://www.washucsc.org/~jha/test.dxf that demonstrates this problem. This model is a simple block with a hole in it. The faces that attach from the sides to the hole are missing. The interesting part is that not all the faces are missing, just some of them.
Any ideas why this might be happening?

When you import, change to edit mode and select all verts. The remove doubles. DXF format has a tendancy to make a lot of double verts. THis should fix most of your problem.
You will still have to clean up the mesh a fair bit though after you do this.

It's propably a bug.
Try changing a 1 into a 0 somewhere in the sourcecode.
It's usaly a sluggy bug like that in blender.
"It works on my cube" is a know programmers "test" case.
I find importing dxf in 2.25 works alot better.

i imported it in cinema4d 6 ce+ and it looks like it should. so it seems to be a blender bug. but i exported this file in cinema4d as dfx again. this new dxf file made by cinema4d looks in blender like it should without the missing faces!!! after this i compared the two dxf files with an editor and they looked completely different. so it seems that there are two different versions of dxf files.
