Smooth Printing - DISPSILH & HIDEPRECISION

#1
I am coming from AutoCAD and used DISPSILH and HIDEPRECISION to print circles and holes in 3D to look smooth. These commands are in CMS Intellicad but even when set they do not smooth out the 3d Object. This is about to drive me crazy.

How do I smooth this out for cleaner prints?

Thanks.
