Hidden lines visible only when panning model?

Seems like video card issue to me. Can you post your computer spec including video card and its driver

Hi Tyler, clearly that part is contributing to this as per the second video the issue didn't exist until it was inserted- it may therefore have some graphical corruption. Are you able to provide that part model to this post? Also may be worth disconnecting and disabling your 3Dmouse add in just to rule that out. reboot SolidWorks and work exclusively with the normal mouse, but as said what you have shown in the video points to the part itself being the cause.

Hi Tyler,

Are you running the latest supported graphics card for your version?

Start>> SOLIDWORKS RX>>Diagnostics.

If out of date it will give you the option to do so.

hopefully that resolves the issue but if not let me know.

Assuming it is an issue with that particular part rather than your graphics card/driver

and assuming the file is proprietary and therefore you cannot attach it here -

and assuming the geometry is complete...

Try saving as STEP and/or Parasolid and read back in and run Import Diagnostics.

Does it pass quality check?

Also, you might try dragging the rollup bar up the feature tree and see if the issue suddenly disappears.
