If this was in SketchUp (as opposed to LayOut), then perhaps manually fix it, with the normal SketchUp tools? Can you determine what geometry was changed by the verification operation (e.g., by using the Solid Inspector2 extension)? For what it’s worth I never ask SketchUp to attempt to fix geometry changes caused by the verification operation, because I don’t know what it’s going to do. If there is no clear “damage” to the model, and the Save function succeeds to save the model to a file, maybe you could ignore the issue (though it may represent some type of software problem that the developers would want to know). ---

The issue has been around for a while, for me it often is the result of the pipe-along-path script which creates a bad intersection somehow. I will attempt to reproduce it. ---

It is not a virus, but a bug that somehow corrupts the model’s geometry database. Some reports suggest it happens when an imported component has the same internal name as the file that contains it. ---

I managed to fix it by making my 3d model a group and then exploding it, I then changed the name of the model (added a number) and was then able to save as and export/take screenshots hope this works for everyone else. Let me know how you get on… ---

I got the same issue. I tried select-all and delete so there was no geometry left in the model at all, and it still did the same thing, so it wasn’t a geometry problem. Next I tried select-all, copy, new file, paste and then the problem went away. I’m guessing there was something weird like it hadn’t deleted a line properly, so it wasn’t available to the user, but it wasn’t fully gone either. Anyway - hoping this might work as a solution for others. ---

Changing the colour of one component allowed me to save with no error. I then changed the component’s colour back to what it was before and the model saved normally. Thanks! ---

I opened another instance of Sketchup, and copy/pasted my work into it. That instance saved just fine. Still, nasty error.
