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.
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?
