The initial Rhino + Grasshopper design essentially dealt with distances from a starting Wall and the interaction between points on the wall and points moved away from the wall. The points moved away from the wall formed the Ballet Barre and the points on the wall became where the supports hit. The lines connecting the two sets of points were used to form arched supports.
The annotated image shows how the Grasshopper inputs are affecting the proportions of the Barre in Elevation. This familiarization allows for a reinterpretation in AutoCAD.
The AutoCAD iterations use the same geometric relationships as the Grasshopper model. AutoCAD however has different tools to construct and parametrize geometry. Where Grasshopper assumes the information needed to create parametric curves, AutoCAD requires the information required to create the curve be parametrized first. Once the “construction lines” for the model are set, then one can attach curves to that geometry.
