Screen Jitter While 3D Rotating

[cadPNYBN]

This behavior just started yesterday in Plant 3D and apparently I can't find the correct keywords to describe it. Video attached.

3D rotation via Shift+middle mouse button is now "jumpy" whereas yesterday it was much smoother. It is making my eyes bonkers.

Does anyone know what could be causing ths?

Hi,

have you tried to restart your workstation?

If you have multiple monitors then try to run AutoCAD on the other display and try the same again.

Not that easy with Plant 3D, I know, but does the same happen if you copy the objects into a new drawing?

At least please send us two screenshots, one of command _GRAPHICSCONFIG and a second of command _ABOUT.

I had a brainwave and typed 'autocad scroll broken' in Google and found https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/Zoom-d...

Simply unplugging and replugging the USB mouse corrected the problem.

D'oh.

Thanks.

Well, restarting the workstation would then have solved it too 😉

A restart should always be the first thing to try when something happens strange or not expected ...

Anyway,it's working and this is the most important thing 😉

Yesterday I did restart Plant 3D and when that didn't work, restarted the computer - no fix. This morning after the machine had been off all night the problem persisted.

I have two mice attached, wired and wireless, and the behavior stopped when I replugged the wired one. The computer had been working properly with the 2 mice attached for weeks. Just one of the joys of working with software, I guess.

Thanks.

Hi,

>> I have two mice attached

Well, if two devices are installed to control one item (two mice for one cursor) it has a potential for conflicts.

You will have seen this sometimes that a mouse moves the curser even without moving the mouse ... this can happen e.g. if  there is a hair in the optic part of the mouse, but also for some other reasons. That's interesting that you were able to do this without any issue yet, but I would not recommend to do this (besides of 3d-mouse parallel to normal mouse, but they behave different).
