Hi!
I was wondering if MOI3D has a better exporter for .dxf file?
I have nurb models but when I export them fro Rhino in .dxf file meshes all get messed up.
Any hope with MoI3d?

Hi Kreten, MoI's DXF exporter (which is new for MoI version 3) is focused on 2D drawing output, generating stuff like lines, arcs, circles, etc... - not mesh output.

But Moi does do mesh output to several other polygon mesh file formats, one of the most commonly used is OBJ format.

What program are you trying to import your mesh into - why is it that you're using DXF format for the mesh transfer? DXF format is not generally very good for mesh transfer since it has limitations on the number of faces that can be in a single mesh.

its an old rendering program called lightscape.
you can import .dxf .dwg. .3ds files

Hi Kreten,

> you can import .dxf .dwg. .3ds files

None of these are very good formats for polygon mesh data transfer, they all have limits on the number of polygons in an individual mesh object, and furthermore 3ds can only contain triangles in it.

Also none of these formats allow for the vertex normals smoothing information to be transferred with the mesh, the lack of which can easily result in shading glitches inside the rendering program.

Probably your best bet is to use a different rendering program that can consume a better file format such as OBJ format, getting the vertex normals to come through to the renderer will solve a lot of shading problems.

If you want to see if MoI's mesh generator can help you out though, what you would probably want to do is to export out from MoI using OBJ format (use the "Output: Quads & Triangles" option when saving), then bring that OBJ file into Rhino and save it out from Rhino as a DXF or DWG file.

But it's not good to be forced to use only dxf / dwg / 3ds for polygon mesh data transfer because the lack of vertex normals coming through will usually make for some messy shading results in the rendering.

Will try what you said.
Thanx!

p.s. Michael how long is MOI running now, 7 years?
DO you have any new feature list for V3?

Hi Kreten,

> p.s. Michael how long is MOI running now, 7 years?

It's been about 10 years now since I first started the initial work on it... Time flies! First public release was about 7.5 years ago.

All the release notes for new stuff in V3 is gathered here:
