I use the software to slice and print objects wich are suppose to fit together. I can do that with for example slic3r but with simplify3d the holes are to small and the outlines are to big. I'm talking about 0.5mm in a 19mm hole (it's 18.5 actally). That is not a big difference but it causes that the parts not fit together.
I could rework the CAD but in my opinion the error has to be eliminatet on the origin.
Perhaps someone has a similar problem, eventually it is possible to tweak the extrusion with. I have this parameter on auto and it calculates 0.6 for a 0.5 nozzle.
