UCSDETECT (System Variable)

Controls whether dynamic UCS acquisition is active when creating objects involving 3D planar surfaces.

Type:	Integer
Saved in:	Registry
Initial value:	1

You can align the UCS dynamically when your cursor hovers over a planar face on a 3D solid, a planar mesh element, or a planar point cloud segment while as you create an object.

Note: Dynamic UCS alignment does not detect planar surface objects or 2D geometry.
