So I've been using Google's rather cool sketchup v8 to design my own, more G1-inspired weaponry for my classics autobots. I've gotten pretty good too I dare say, especially considering the free version of sketchup is fairly tool-limited. My problem? Apparently a scaling issue! I always select product design- mm in sketchup, draw to the final scale I want the piece to be, and export as an .stl file (read A1's post about them being better than .dae files) for uploading. But both designs I've thus far tried to upload have returned with a scaling issue. Now customer services fixed it first time, but didn't explain at all what he'd done (so I also don't know if he preserved the dimensions I wanted, as I can't reopen the fixed file in sketchup). I was wondering if anyone experience in sketchup and accutrans/meshlab could provide a short guide/tutorial for correctly scaling a design for uploading? Thanks!
