Rhino files become lag all of a sudden

I have been using rhino for quite some time and this never happens to me. The file has suddenly become lag when I was trying to switch from wireframe to shaded mode. After some time the file appears normal again on these commands. However, trimming, contour, offset etc. have suddenly takes ages to happen when it usually just take a second.

Any guidance how to solve this? Any kind help will be very appreciated!

Well, the video driver is a little out of date, you need to keep video drivers AND Windows AND Rhino up-to-date. That would be the first thing to make sure of.

Hello - can you please run Audit3dmFile on this file and post the results?


Hi, sorry for the late reply. It’s okay. I have deleted one of the object that I have newly generated and the file is back to normal again. Thanks for the reply
