I’ve spent 35 years at the drafting board — surveys, land development, Civil 3D — as a CAD specialist in Ontario. Acheck came out of that: I got tired of checking parcel closures the slow way, so I built the check I wanted, right inside AutoCAD and Civil 3D. Segmented Bowl Designer came off my own lathe — I turn segmented bowls, and I wanted the ring counts, miter angles and cut list right before I glued anything up.
These are the tools I use myself. If they save you a re-check or a wasted blank, that’s the whole point.
