Curves incomplete display

Parts of the curves are not shown completely, depending on the zoom size.

I see this in V6-V8, but V5 is good.
The curves were imported from a DXF file.

Hi, @Charles. I can confirm this is an issue related to OpenGL 3+. You can downgrade to OpenGL 2.1 in Rhino 8 to solve the problem as a workaround.

Tools > Options > View > OpenGL > Level > OpenGL 2.1, then Restart Rhino.

Let us know if that helps.

@stevefuchs it is best to make YT issues for this. Lowering OpenGL levels is not a good solution as this will reduce capabilities of Rhino in other ways.

Is it really related to OpenGL?
I thought it is an import issue.

The offending curves are weird:

When importing the DXF in Rhino V5, the result are 3 lines.
Unfortunately, I can’t send the DXF to here, but as PM.

Hi, @Charles. It’s in our system for developer investigation, now. You can follow the progress via the YouTrack link above. If you PM or email me, I’ll add the DXF to the report. steve.fuchs@mcneel.com

NOTE: DXF sent and added to YouTrack
