Organic Shape Feature-Based CAD

Overview

Organic Shape Feature-Based CAD

Extracting features from organic shapes is a challenging task. In an existing NURBS Model, we can add or edit the features based on the client’s requirements. The process of creating and manipulating NURBS surfaces and solids is supported by feature-based operations. Organic shape feature-based modeling with T-Splines(a combination of NURBS and Subdivision modeling) is different. It most often involves starting with an initial mesh shape, subdividing it into areas that need more detail and refinement, and pushing or pulling on its surface to deform it into the shape you need. Manufacturable products with organic surface features likely include both Subdivision modeling for aesthetics with NURBS modeling for precision. The best example for organic feature-based CAD is a haptic device with reverse engineering software. This organic Feature-based modeling software allows analysis of drafts, creation of inserts, and parting lines for both CAD and scanned models.
