Hi, is it intentional that redrawing selected objects are 3 times slower than unselected objects?
If you want to test it for your self then just make an array of 50 x 50 spheres in wire frame mode and Zoom Extent them and run a testmaxspeed, then select them and re run testmaxspeed.
This makes a huge impact on moving large amount of data, something that is of interest for architects.
I see that unselected objects uses a simplified proxy (jagged polylines) when redrawing, while selected are smooth. Is the reason that the curves has to be accurate for snapping to work properly?
