when you select the file tyoe *.stl for open/import, bottom right "options",
you will be able to select "units"- millimeters, centimetres, metres, inches or feet
if this is not what you're after maybe post the stl you're haveing problems with,
I'm sure someone could resolve the problem,
hope this helps- have a good'n kelef
That's it! I was thinking of the Tools-Options menu, not any settings in the Open dialog box. Thanks!
glad to have helped, dude, re: "so it's ~100 feet long"
that should not be the problem as 1640.4' is the max dimmension,
from origin the model needs to stay within this boundary- kelef
