For us, the last setting made all the difference.



Great stuff!

We recently had some issues with this. Couple things we did that helped.

1. Spaceball - If you are using one try stopping the driver and see if it improves the redraw rate. Had to buy all new spaceballs and update drivers for many here.

2. Cross-Hatching - Any section views were coming in with a cross hatch spacing of .001 mm or something tiny. The result was cross section drawings that had hundreds of thousands of tiny lines, which was essentially a solid block of cross hatches. Wrote a macro to set all spacing to '1' and it greatly reduced redraw times.

3. Work-Around - try moving the view you are working on to a second sheet, editing it there, and then moving it back.

Hope you fid the culprit
