Purpose: Let users import a CAD model with a full (through) crack and automatically detect the crack, convert it into a repairable patch surface, and apply direct-modeling operations (heal, fill, blend) to produce a manufacturable solid while preserving intent where possible.

Direct Modeling is a CAD approach that allows users to create and modify 3D models directly, without the need for complex parametric histories. This method contrasts with traditional parametric modeling, where designs are constructed through a tree-like structure of features that define the model. Direct Modeling offers a more intuitive and flexible way to work with 3D models, making it easier to make changes and explore different design alternatives.
