Comparing Fabrication Workflows in CAD to Support Design Reasoning

Figure 1: We study the value of comparison in CAD to assist reasoning around fabrication workflows. To this end, we implement an exemplary tool, CAMeleon, that enables learners to explore and compare fabrication workflows when initial design assumptions no longer align with their goals. (a) A learner imports a Stanford bunny model into CAMeleon. (b) The model displays with side-by-side previews of alternative workflows (e.g., wire forming), highlighting differences in assembly processes, materials, and machine constraints. (c) Learners examine detailed technical information through the workflow information panel for deeper comparison. (d) The final physical outcome (e.g., a bunny lantern) is fabricated using the selected workflow.
