The CW tool is pretty powerful, but it works only in the vertical plane as a 'wall'. The panelisation that the CW tool is useful as a lot of construction objects are based on panels and grids. Eg Cladding panels and frames, tiles and joints, celing panels and support grids, tunnel linings, internal paneling etc etc. A lot of construction products come as panels or sheets that have to be assembled into arrays.

The parameters used in the CW tool seems to be based on the global coordinate system. It would be great to replace this with calculations based on a CS based on the individual local transformation of the CW object. This should allow the CW object to be rotated and maintain coherent, more reliable parametric control.
