Snap function used by the Draft tools
Currently has two modes: passive and active. Pressing CTRL while
clicking puts you in active mode:
- In passive mode (an open circle appears), your point is
snapped to the nearest point on any underlying geometry.
- In active mode (ctrl pressed, a filled circle appears), your point
can currently be snapped to the following points:
- Nodes and midpoints of all Part shapes
- Nodes and midpoints of lines/wires
- Centers and quadrant points of circles
- Endpoints of arcs
- Intersection between line, wires segments, arcs and circles
- When constrained (SHIFT pressed), Intersections between
constraining axis and lines/wires
