When I import a STL file to Luban it appears distorted and out of proportion.  
Any ideas?

Can you post the file or a link to the file? Is this an STL you created, or one you downloaded? If you created it, which tool did you use.

Some of the modeling tools use units of inches, and Luban uses units of millimeters. So some objects created in imperial need to be scaled up by 2540% to be the intended size.

It will be helpful if you can share the STL file that have that issue. You can share a link to it.
