A basic method of applying parametric variation is tested.  Starting from a control model as a straight wall, variations of the flat wall were generated in CAD. Each variation constrained the flat nature of each panel. After each model was adjusted to a finished position it was developed to a 2D drawing, laser cut and assembled by hand with glue.  These models demonstrated a lack of consistency between the parametric models and the physical artifacts. There were many gaps between panels represented in blue.
