Most of the meshes visible in the image below (meshes were imported from sketchup) display as translucent in Rhino 8 in Pen mode. I updated my Nvidia display driver yesterday (the display yesterday was correct after that) so I don’t suppose that’s this issue. I’ve tried RebuildMesh on some of these objects to no avail. I will upload the file to tech support. Yesterday these objects displayed properly in a previous version of the project, and those objects in that version still display correctly today. I’ve attached exports of two versions of the same tile. Today’s is translucent, yesterday’s is opaque.
Thankyou User454. That did it. I wonder what flipped them in the last 24 hours. They didn’t come in that way from Sketchup so I expect it happened in Rhino.
Japhy I’m assuming uploading the skp file isn’t a fruitful direction, but please let me know if it’ll be useful.
As work has progressed, I had another of those objects flip after a relatively straightforward operation. (Scale, rotate, perhaps bend, I have forgotten. No flip command.) Flip restored proper display. It seems like something’s not quite right for that to happen.
