Not sure if this is a bug in Sketchup or my model.
I have a fairly complicated model that I created in a previous version and now I have 2022. I need to make some changes and as soon as I make a change my scenes literally disappear.
While looking at my “site plan”, I turn off the visibility of a single group and the viewport is empty. I turn the visibility on again and the scene is still empty.
I notice that, when in the scene and viewing it, if I tilt teh model (it is in parallel projection) and the scene also goes blank. But if change it to perspective view, it comes back.
Either I am missing something or there is a bug. Very frustrating as I need to modify this scene to produce a delta for an ongoing project, under construction.
Just changing the camera back and forth makes the scene larger and moves it in the window slightly. THen in Layout when you import the scene it changes the location in Layout. Not the scale (if I have a scale that is set which is almost always the case). I then have to relocate the scene in layout, which may be multiple layers that have to be relocated.
I went into my original file and ONLY did the TIG fault Geometry and I lost all my scenes. If I do like you did and go through each scene and change the camera from Parallel to perspective and back, it returns.
I think the main problem is incorrect tag usage from the beginning. If you had been using tags correctly–ALL edges and faces untagged–you wouldn’t have had the problems at all.
