I'm exporting files to OBJ and they are coming out in the 500 Meg range. As you can imagine these files are choking the programs I am attempting to bring them into. Is there anyway to control the size or settings for OBJ files?

Thanks,

Joe

I like when I answer my own question! :)

Set the display to a lower setting. I went from Super Fine to Fine and that greatly reduced the file size. An option like the Rhino export would be nice -- Rhino gives you a slider to set the amount of polys when exporting to OBJ.

You can control the number facets going to OBJ by:

1. Select the object and do a Edit:Change Object type.
2. Select mesh.
3. Adjust parameters to your liking, hit update to find out how many facets your parameters create.
4. When you get the desired facets. Hit CANCEL!

Yup, hit Cancel. This will abort the model from being converted to a mesh, but leaves the facet display list attached to the model. When you export to OBJ it uses the facet display list currently attached to the model.

OBJ is a nice format as it includes normal per vertex. You don't need as many facets to make an object look smooth. Plus the normals are calculated directly from the underlying NURBS so they are precise (Not an average of adjacent normals).

Thanks for the tip Tim! I'll be using it this weekend!

On this subject, is there a way to quadrify flat surfaces? Over at Turbosquid and Renderosity, they like models with quads, and as few triangles as possible. And don't even mention n-gons.:mad:

I'd like to build stuff and render it in Carrara.

MOI can export with quads and triangles, but I don't want to fork over $300 just for the export feature.

In other words, if I have a cube with a hole, and convert to mesh, the flat surfaces are triangulated. Is there a way to specify that the flat surfaces be quads?

By the way, I am using ViaCAD 2d/3d. Does Shark have this ability?

CANCEL? Why not "apply new mesh settings" or something like that? Cancel suggests not going forward with the work you just did. Could this change sooner than later?

>>CANCEL?

Otherwise it will convert your surface or solid to a mesh object.

I see. So, is there a way to separate the process ( an additional button or something similar) to make either a mesh or attach the facet display to the model for export only?
I think this would help to improve exporting of mesh models/surfaces from NURBS. It would be a good feature to add.
