Moire Issue VW 2020

[kiddkolor]

I am in working in VW2020 SP2.1 on Windows 10. I recently began having issues with a moire effect on all or some model surfaces. I had assumed this might be an OpenGL issue, however even with OpenGL settings on High the issue persists... Both in model space and view port space. Hoping someone out there has idea what the heck is going on, as I have a pending deadline in the next 24 hours to deliver drawings to an HOA. Ugh...

2 things to check:

 

1.  Two objects occupying the exact same space.

2.  Geometry that is very far from the drawing origin.

Hello kiddkolor:

If you are using Draw Edges in the OpenGL Options, stripes can happen when multiple surfaces are in the same location.

 

Usually a comb or striped effect is from multiple overlapping surfaces.

 

Another way to get this is when multiple layers or classes with the same objects in them are set to visible.

In addition to the points above, check that the "Crease Angle" under OpenGL Options isn't set too low. Should be around 70 or so.
