Hello,

I am using your software with Mars pro.

I am making mechanical parts.

All parts are printing undersized.

I am using sketchup to create the part.

I am using millimeters to dimension the parts.

I have created 30 plus parts and all are underside.

example

    a 20mm wheel is under by .3 of a millimeter on interior bearing surface and exterior circumference.

    a 60mm wheel is under size by 1.3mm

    This is a under size ratio of 97.5 to 98.0

This is not usable for me.

How is this error corrected?
