Why is Rhino Redraw speed on selected objects 3 times slower?

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?

Thanks.

Thanks for reporting this. We’ll try to improve this speed for V6.
