Rectangle
A rectangle in one gesture: plates, pockets, bosses and the outline most parts start from. The tool writes four lines and the constraints that keep them a rectangle, so every side and corner stays editable afterwards.
Polygon
A regular polygon in one gesture: hex bosses, nut pockets, octagonal bodies. The tool writes one line per side around a guide circle, plus the constraints that keep the sides equal and the shape regular — and one dimension, the circle's diameter, resizes the whole polygon.
Slot
A stadium — two parallel lines closed by two semicircular caps — in one gesture: adjustment slots, keyways, open notches. The tool writes two lines and two arcs with the constraints of a slot, so the length, the width and the position all stay editable.
Text
Text turns a string into outline geometry: each letter becomes a closed profile, counters included, that extrudes, cuts or wraps like any other sketch shape.
