This is my first upload. It is a 2' x 1' box with left and right side with square holes. It is a seriously simple object and fits within the bounds of most if not all materials. Wall thickness is 1" and 0.5" Sketchup DAE export.
After it uploads, every single material says "Loading" in the autochecks. column.
If I go to my models and check "show unprintable models", it becomes available for view, edit, 3d tools and delete. If I click on 3D tools, I see a material overview pane where "wall thickness" and "machine space" show a spinning symbol.
And absolutely nothing else happens.
No errors, no messages, just perpetual wait state.
So, what am I doing wrong?
