blender types
Being a CAD guy, I don't know what some of these types are. Obviously, I'm familiar w/ dxf and stl, but these others are foriegn to me.
I find it odd that Alibre can export a stl, but can't import one.
Blender can export:
VRML 1.0
DXF
Videoscape
STL
AC3D (.ac)
Cal3D v0.9
DEC (.off)
DirectX (.x)
DirectX8 (.x)
LightWave (.Iwo)
Motion Capture (.bvh)
Nendo (.ndo)
Radiosity (.radio)
Raw Triangle (.raw)
Truespace (.cob)
Wavefront (.obj)
Wings3d (.wings)
X3d Extensible 3D (.x3d)
