I have two issues I would like help with. First, when I print a cylindrical item the print has very clearly defined stepped sides. The item in the TCW file is round, but when it is saved as a STL file it becomes a regular polygon.
The second question may well be a printer setting rather than a TurboCAD one, but I will toss it out anyway. I want to print some parts with holes that I will thread once they are finished. But to get enough material to cut threads into I ether have to define the part as a solid without using infill or set the wall thickness for the whole part much thicker than most of it requires.
