The geometric constraint commands constrain the orientation of a segment parallel or perpendicular to other features, or to the vertical axis in 3D scenes. They are available when you draw line or polygon feature geometry.
Constrain the current segment parallel to an another feature.
Constrain the current segment perpendicular to an another feature.
Constrain the current z-aware segment to the vertical axis in a 3D scene.
This command is only available with 3D scenes.
