Generate a circle or square starter shape with a loop tab or hanging hole - sized to your spec and ready to bring into your design.
Place holes sized for common bolts, screws, standoffs, and magnets, with the right clearance so the hardware seats without forcing. Set the size and position and add them to your cut file.
Standard bolt and screw sizes, standoffs, and common magnet diameters, with a clearance fit.
Holes can be sized so that, after kerf, the hardware fits as intended.
