3D Modeling, Object Type, File Size

[MattG]

So doing more and more 3d modeling if you will. I am reworking some of my symbol libraries. I have a few files that were in other formats an are very nice shapes, but are meshes. I do not typically use meshes very much. I typically building solids using the tools in the 3d modeling tool set. Is having a 3d mesh a good thing? How will this effect me if I have a large number of these symbols made of these meshes in my drawing. Is it better if they are polys or solids? Just looking for a little insight here.

Thanks,

Matt

In my mind Mesh equals larger files and longer Renders (Even in OpenGL). If you're working with a few small mesh items at a time you may not even notice, but if you're, say designing an auditorium and are using a chair symbol that includes mesh, then good luck... I speak from experience.

I agree with C W.

Mesh objects seem to be a Group containing 3D polys. Maybe someone knows what they would be useful for. I've often found them in objects after importing something created in sketch up or autocad.

The rendering time is brutal.

Yes, meshes are generally to be avoided. Difficult, sometimes nearly impossible to edit; moreover, resource-devouring, depending on number of vertices.

That being said, lots of objects import as meshes (read:Sketchup), so they are hard to avoid. Vectorbits offers an Optimize Drawing plug-in which can be used (with caution) to reduce vertices.

Otherwise, NURBS are your friend, and use symbols and nested symbols whenever possible to reduce redundant calculations.
