< Previous: Construct | Next: Line: Parallel >

A line through a point, at a right angle to another line's direction.

Menu: Construct > Line: Perpendicular Through Point | Node: Perpendicular | In depth: Lines, rays & segments

Pick the reference line (or segment/ray), then the point the perpendicular runs through. The result stays live - move either input and it re-orients.

The tool stays armed on the same base line after each one, so you can drop several perpendiculars off the one reference in a row without re-picking it. Press Esc to release the base.

• In the node graph: Perpendicular - build the same perpendicular as a node.
