ArchiForma 2 - 3D Surfaces
The first one is the Ruled Surface, which generates the surface resulting from the connection between two polylines in the 3D space.
The second one, the Translational Surface, extrudes a 3D Polyline along a 3D Path (defined by another 3D Polyline).
Of course, the two polylines must have a common endpoint in order to let you create the resulting surface.
For last, the powerful Coons Surface, which needs four 3D Polylines, defining a closed polygon, and which lets you create very complex free shapes.
