Generate a circle or square starter shape with a loop tab, one or two hanging holes, or a keyhole - 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.
Yes. Pick Two Holes, then set the hole diameter, the center-to-center spacing, and the margin from the edge. On a circle the pair follows the rim, so both holes keep the same gap to the edge at any spacing.
Pick Keyhole, switch to Two keyholes, and set the spacing. Both slots are cut at the same height and inset from the curving rim, and the tool tells you exactly how far apart to drill the two wall screws.
Holes can be sized so that, after kerf, the hardware fits as intended.
