      It might be a graphics-card issue...
      Have you go the latest drivers ?
      Have you tried editing the Sketchup > Preferences > OpenGL settings to see which combo of them doesn't result in this issue etc...

      Adjusting the preferences did not do anything. In fact, when I toggled them all off the results were bizarre.
      I have an IMac btw

        Is the model or component geometry far away from their origin?

        No it doesn't seem to matter. The component can be small or large and near the origin.

          If you send me the SKP file, I'll take a look at it on my Mac.

            Wow
            I was going to send the file and realized it is 5.6MB (2 MB max) although there is hardly anything in it. What gives?

              Probably a bunch of components you'd made but deleted? Or some large imported image? Go to Window>Model Info>Statistics and click on the Purge Unused button.

                  I saw it too. I think it is something related to clipping. The camera is set to Parallel Projection and is also set to be at a long distance from the model. If you switch to Perspective it looks like the model disappears. Zoom back in on the corner of the model and then switch back to Parallel Projection. It doesn't happen then.

                    What is "clipping"?

                      It's basically when some of the model is behind the image plane of the camera. There are several things that cause it. It is more common when the camera is set to Parallel Projection and it commonly happens when the model is very large (geographically), when the model is located at a substantial distance from the origin and/or when you zoom in on a small part of the model.

                          Any time.

                          TBH, I don't know if this qualifies as a bug or it's just the way it is.

                            I guess though I'm curious why it never happened before a few months ago. In fact , the last time you you helped me one on one I mentioned it to you. It had just started shortly before that time.

                              I guess I don't know. I almost never see it but I don't tend to use Parallel Projection while I'm drawing except for once in awhile to make selections easier. It doesn't tend to show in Perspective view.

                                I generally find that parallel view often produce clipping glitches.

                                  It's good to know it's not a problem inherent to my machine.
