Hidden lines visible only when panning model?

I just started experiencing a problem with a model where hidden lines become visible only when I am panning around the model. When the view is stationary the model displays correctly. I am using shaded with edges display style.

Additionally, when I insert this particular part into an assembly the assembly then becomes infected with the same problem. This only started happening yesterday and I never experienced problems with this model or this particular phenomena before.

Attached are .mp4 videos of this problem.

I'm using SW2017 and just updated to SP4 this morning.

Correct Answer

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.

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

You got very good video card and I can't think any issue from that card

So this problem only happened to this assembly or to others assemblies?

I saw something similar when I have some overlap parts in assembly, but not like happened to all as you showed in the video

Your VAR might provide a better help !

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If out of date it will give you the option to do so.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

So far no good. Also restarted SW without the 3D mouse add-ins. But wait there's more...

Can you post this individual part which might cause the issue?

Rolling back over the last plane rid the model of the problem. See video. Why the part just started this error is still in question. Otherwise thanks everyone!

Furthermore, as I look at the part file and this particular feature (Plane 7) I notice that the plane is extremely far out in space. So much that zoom extents makes the part not visible (fitting both the part body and Plane 7 in the same view (isometric)). I'm not sure how this happened due to the fact that Plane 7 feature is based off of a midplane reference between two existing planes located on the sides of the part.
