Perpendicular Snap tool

Use the Perpendicular Snap tool to snap to the perpendicular point of another entity. You can snap to an arc, circle, ellipse, line, polyline, infinite line, ray, spline, hatch pattern, or edge of a plane to form a perpendicular alignment with that entity or with an imaginary extension of that entity.

To set the Perpendicular Snap

Do one of the following:

  • Choose Settings > Entity Snap > Perpendicular Snap.
  • On the Entity Snaps toolbar, click the Set Perpendicular Snap tool ().
  • Type perpendicular and then press Enter.


To form a perpendicular angle (A) to an entity (B), select anywhere on the entity.
