A flat, closed Profile outlined by one or more curves joined end to end, in the order of the rows; each curve is turned to run on from the one before it, so curves picked in either direction join. When the curves close a loop, the Profile lies in that loop's own plane; otherwise Normal sets the plane.
The outline curves in order around the loop, as rows or a wired Curve List; each may run either way.
Plane direction, from a wire; replaces the typed value.
Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.
The flat region as a zero-thickness Solid, the zero set of its distance field.
The axis-aligned extent of the profile.
Distance to the region extruded without end along the plane normal (an infinite prism).
Distance to the flat region itself, with no extrusion.
The plane the profile is drawn on, with its origin, normal and frame.
The closed loops that bound the region.
