Is there sth wrong with my laptop? and is there a way to make my file smaller?

Hi Alisa -

I’m not seeing any crash reports from you. Does the crash reporter window pop up after the crash?

The autosave doesn’t save display meshes in the file. You could use the SaveSmall command to save without those display meshes.

Other than that, does changing the advanced setting Rhino.Options.Advanced.UseCompressionWhenSaving make a difference?
-wim

There was no crash reporter, it just takes very long time to load and freezed, “not responding” for a long time.
How do I change the advanced setting?

Hi Alisa -

That doesn’t sound like a crash. You could check in the Windows Task Manager to see if there is still any CPU activity for Rhino.

Go to Rhino Options -> Advanced:

-wim
