Cura Parts Fit Perfectly! (the Diameter Dilemma)

[LesHall 95]

Correct me if I'm wrong, IIRC slicers have always "straddled the line" when drawing outside shapes, so I had to add a "nozzleDiameter = 0.4;" parameter to my OpenSCAD files so that I could add or subtract it or half of it as required to make parts fit together. This was really annoying and led to many a failed print where a precision fit - or any fit at all - mattered.

So it is with more than a little joy that I notice this seems to be no longer necessary with the latest Cura (2.3 at this time and forevermore I hope). One imagines that Cura is now smart enough to recognize the curvature or "outside vs inside" of a part and adjusts the print head to draw such that the edge of the part is reached and not exceeded.

Thank you Cura developers - you made a (not quite yet) old man happy!
