I have been using Sketchup for several years and never had this problem. I export an stl file, and it gets rotated. No matter what I do, the same thing happens again and again.
When I am done editing my model, and I’m ready to export an stl, it looks like this:
I export the stl, then re-import it, and it looks like this:
It remains like that when I open it in Meshcam to create my g-code.
I’ve tried everything, including rebooting my computer. I cut and paste the model into a new Sketchup window, I import the stl, edit again to straighten it, nothing works.
Its always about 2.4 degrees off on the Z axis, and .3 degrees off on Y.
