A flat, closed Profile whose corners are the listed points, in order. The last point is joined back to the first.
The corners, in order (at least three). They should lie on one plane; points off it are projected onto the best-fit plane.
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.
