This is a 2D drawing. If I just look at something I have done I can see most things…
…but when I zoom in or out just one time on the mouse many things disappear:
And some things might almost never be shown. Not necessarily components, but parts of a line for example:
I assume the drawing is not completely flat, maybe some surfaces are on top of other or ended up a tiny bit above some somehow… Is there a way to let’s say mark the whole drawing and choose to make everything in it completely flat?
(I have had thins problem pretty much ever since I started with SketchUp many years ago.)
