ReparamCAD: Zero-shot CAD Re-Parameterization for Interactive Manipulation
SessionNavigating Shape Spaces
DescriptionParametric CAD models encode entire families of shapes that should, in principle, be easy for designers to explore, but are in practice difficult to manipulate due to implicit semantic constraints between parameter values. Finding and enforcing these semantic constraints purely from geometry or programmatic shape representations is not possible because these constraints are ultimately a form of design intent, and are informed by the designer's experience and semantic in the real world. While individual pieces of geometry cannot encode this contextual knowledge, is it encoded in large foundation models. We use large language and image models to understand what the meaningful space of variation is for a shape, and synthesize a new parametric CAD program that captures these variations, allowing for easy design space exploration along meaningful design axes.
