I'm using WF3 I've two layers hidden, one contains surfaces & the other one contains curves, if I have the model in "hidden line" or "no hidden" modes they don't show, as they sup suppose to, but if I switch to "wirefrane" & "shading" mode, the surfaces and curves in the hidden layers are shown. What to do? Or this is another one from PTC, when they take something that had been working forever and stop working with a new version.
