Sketchup glitching

Hey guys, I’m not sure what happened but all of a sudden my model started glitching hard. I’m not sure how to resolve this issue. Please see attached screen recording. Any advice for a remedy would be greatly appreciated.

Looks typical of when the model is located at a great distance from the origin? How far away is it from (0,0,0)?

I’m not sure. How can I check?

If you still have that box you drew in the video, use the Text tool to place a label at one of the corners. It will give you the coordinates of that point.

Doing this did not show the coordinates. Is there any I also checked in the components options and that window was completely blank.

Sorry I was using the 3d text tool. I used the normal text tool and it this is what it displayed

In your video the axes do show up, which would suggest you’re not far from the origin, but were you inside a component at the time you did the recording? If you were, come out of editing the component, then with the tape measure tool point at any corner or line ending. Something like this will show up, see if you can get a screenshot.


OK. So that’s not that far away. What happens if you click on Zoom Extents?

It zoom extends to fit the model in the whole screen.

Can you share the model file?

It’s a camera distance issue. Switch the camera to Perspective and then hit Zoom Extents to get back to the model.

Best to work in Perspective while modeling anyway and reserve Parallel Projection for output display.

Wouldn’t hurt to purge unused stuff once in awhile.

@DaveR is, as usual, spot on. This is an example of the perils of editing a model in parallel projection. Zoom doesn’t work the way one would guess when in parallel, and it is possible to get the camera a vast distance from the model without altering the view. In this case the camera was about 4million feet from the origin!


Thanks so much!! I wasn’t aware that I should be purging unused stuff. I’ll look into doing that as well.

It’s funny to come across yet another variation of the issue.

Not the first time we’ve seen it, though.

I was only remembering the far away geometry variation.

I think something has been done recently to the parallel projection camera. Previously problems were mainly with clipping, caused by the camera moving to inside the model.

It has always been the case that in parallel projection zoom works by changing the scaling of the model onto the view, not by moving the camera. Because the projection rays are parallel, camera distance has no visible effect. It’s possible that a change intended to reduce clipping in 2020 also affected camera positioning. But I’ve seen the camera go astray in earlier versions too.
