I was recently asked to split a model for a client and the part had such a high face count that solidworks couldn't work with it (it could be a mesh but would not turn into a surface or solid) and meshlab would crash when I would try and reduce the face count. According to meshlab the part had 1.7 million faces. Would it be possible to have a face reduction feature in as a tool for clients or even the hubs themselves?
So I found out the issue that I was having with MeshLabs. When I was simplifying I was not using the planar simplification option. When that is selected it significantly increases stability and it takes about 2 seconds to complete even on a laptop. I have uploaded a picture outlining the Important parameter.
