UPDATE !
Goodness me! Somewhere around 3-4 hours later, the file was indeed imported. The virtual bust of me is rendered huge – my head must be about 15 feet tall. Hilarious. That’s too much me!!
And fair enough, SketchUp is having trouble working with the file. And even if i shrink it, it’ll still be the same amount of geometry. What I need is a lower-res version of my imopressively huge .stl file.
So then the obvious route would be to find a utility / application that would reduce the size of the .stl file to something much smaller before trying to import it. Any ideas for such a program?
