Hello.

I have a quick question as the title.

When I import the cad or any file to Rhino 8, all the line or surface too bold in all view as image below.

I use draw line or surface in rhino 8, there is no problem.
Only import any file to Rhino 8, It happens.
I can’t do any work right now…

Do you guys have any idea of this?

I tried to restore defaults in view or any rhino options, but It never changed.

Hello @조혜정
Could you send a sample file you try to import? Most likely there is a line width setting that needs to be addressed.

Also, pls run _SystemInfo in Rhino and post back the results
