Geometry Check

About

Geometry Check is a Fusion 360 add-in that finds slightly wrong sketch geometry: lines within 0.5 degrees of square, hairline gaps between endpoints, open endpoints and tiny sliver segments. It explains each finding, selects the entities and zooms the camera to them. It only detects by default, and an opt-in mode adds a Fix button that applies a constraint and undoes it automatically if a re-check fails.
