polygon meshing

proces2 · June 5th, 2006

I have a polygon mesh from Rhino that i need to simplify. Is there a software out there or a plug-in for something like Rhino or MAX that can take a large polygon mesh and cleanly simplify the model - ie - reduce the poly count?

This is for a model that is being built on an SLA machine. Because of the current high poly count, the machine will not accept the file.

i looked at something like PolyTrans, but it was hard to determine if that was a function inside the software.

any suggestions would be great.

thanks,
sean

Optimize doesn't doesn't do it well enough?

Have a look at Deep exploration - their CAD tools have a good poly reduction tool, not sure about price, but it's a handy bit of kit for viewing heaps of different files.

downloard rhino 4.
"QuadrangulateMesh"
this may reduce your mesh count 1/3

Are you meshing a nurb?

To do so do the following:

reduce it to the size of the part 1:1 scale.
make sure your units are in inches.
then mesh using these settings.

maximum angle: 0
maximum aspect ratio 6
minimum edge length .0001
maximum edge length 0
maximum distance, edge to surface .001

Check:
Refine Mesh

all else unchecked

export.
