Whatever I’m modelling, Rhino becomes unusable after about three hours. The colour wheel keeps appearing every ten seconds and it’s just impossible to work with it. Have done a ClearUndo, no effect. The files are only small, less than 1Mb. No Plugins are being used. Geometry and models are very simple. Just making planar Solids, no fancy stuff.
It might be related to executing MAKE2D and having a number of dimensioned line drawings and Panning the view. But again, they are very simple primary shapes and should be a problem. Simply panning appears to take CPU usage up to 100%
Am using iMAC 3.4GHz, 8GB Memory.
Any thoughts anybody?! Simon
