I’ve been using Rhino 3D for over 4 years now, and I’ve never had this issue come up before. I spread my workload over my office desktop and home office desktop… both are similar machines and run current copies of V5.
I started building a model of a trade show booth a few days ago on my home PC, worked on it at my office and then went to work on it again at home. I found a portion of the components seemed to be “missing” in rendered, shaded and pen views. I thought that I had accidently deleted something, but I found the pieces… but they were invisible. I could highlight the pieces, I could modify them (scale), but they had no fill, or lines. All layers were visible, no objects were hidden, I didn’t have any transparency applied to the pieces, and there was no texture mapping. When I opened the file back up at my office, everything was normal again.
I build a large portion of my models with closed polylines extruded to a required size. Just trying to troubleshoot, I exploded every surface in the model… which made everything visible again, but I couldn’t create solids at this point.
Rhino has always been a stable program for me, but I can’t think of anything else to look at right now to make sure that I don’t have this happen again. Does anyone have any suggestions for things to look for?
