This document contains summaries of three assignments for an introductory computational fabrication course: 1. The first assignment involves developing panelization strategies for a facade surface using parametric modeling and analyzing solar irradiation with DIVA. 2. The second assignment compares different CNC toolpath strategies for machining an image-based surface including parallel finishing paths with varying ball sizes and stepovers. 3. The third assignment experiments with using control point density on a lollipop surface to generate different patterns for CNC toolpaths.
