Graphical issue_Rhino 8

Rhino Rhino for Windows

Hi,

I noticed strange model appearance in both shaded and wireframe mode (attached pictures 1 and 2). It started after installing last update but I’m not sure this is connected. This is happening on two different computers, both with an older graphic card. I saved the model back to version 7 and in Rhino 7 it looks normal (picture 3).

@gorles_82 pls run _SystemInfo in Rhino and post back the results

These are results…

the first thing to try is to see if installing the latest drivers resolves this.
Best always to do a clean install

Thank you. When i reopened the file I got notification that model base point is far from origin. Now when I have set model basepoint to origin it works fine. I think that model BP was displaced because I copied everything to a new file and also copied construction plane with base point on large coordinated from original file. But basepoint of original file, where the issue appeared is on origin, so I don’t know… The problem was actually not present all the time but it appeared after working for a while and after software restart it was ok for some time. I noticed before that something similar happens it there is a part of the model very far from origin, so I was checking about this and it was not the cause. So far both files seem to work ok. I will update the drivers and see if the problem comes back…

okay, yes in that case these display artifacts can happen. A driver update won’t help with that.

Yes, I guess it was most probably just my mistake associated with large coordinates. I’m sorry about that…

I think I have found the cause. I made a CPlane for exporting to Autocad, which is far away from origin. When I set up this CP in plan view as current, the symbol is shown in perspectice view and it messes up the graphic display…

Hi GorLes -

I’m not seeing that behavior in a quick test here with a custom CPlane that is at 2.5M,3.5M,300 from the world origin. Please post or upload the 3dm file so that we can take a closer look.

Hi,

this is the file. I noticed same behaviour with other files too. On coworkers computer with newer graphic card this doesn’t happen though. I updated graphic drivers and it doesn’t help.
