Onshape FeatureScript is a new programming language designed by Onshape for building and working with 3D parametric models. The language is built into Onshape from the ground up, providing the foundation of Part Studio modeling, including robust geometric references, powerful parametric tools, and a type system with types built for math in three dimensions. I got an opportunity to explore Onshape FeatureScript and see what we can do and how it can help us accelerate the design process. This blog is about my experience with FeatureScript and what I have achieved in just 3 days including learning and implementation.
