Gaudi-like columns are generated as part of the “boolean” classes of Design Computing. The most inspiring, beautiful, and ugly variations are often done by boolean intersection, as this operation is the surprising one of the three brothers. While the class deals with the concept of emergence once again via solid and void relationships, constructive solid modeling techniques are introduced. Although it is widely used as a spatial analysis approach in architecture, there are some examples of using boolean algebra in actual design processes. CSG trees are one of the interesting techniques that utilize boolean operations with a diagram language. The so-called Gaudi columns exercise uses macro explication instead.

This macro we have studied in the classroom draws three profiles, and lofts and boolean intersect them to generate column designs.
