Parametric CAD

Before we talk about scan to parametric CAD, Let's explore what is parametric CAD and how they are typically made?

Parametric cad consists of a history-based feature modeling tree that can be edited to make design changes during any engineering design or product development. They are typically designed in CAD software such as CATIA, UG, Creo, Solidworks, by selecting an XYZ coordinate system reference plane. The user draws 2D sketches and then uses modeling features such as extrude revolve, sweep, etc.

3D Scan To Parametric CAD

is the reverse modeling process done in dedicated reverse engineering software, In which we import 3D Scan mesh as a reference and create a cross-section plane on the 3D mesh file in different angles and dimensions, using a reference cross-section profile we extract 2D sketch or draw 3D sketch directly on mesh file or use few more exclusive modeling technique to make the parametric model from the 3D Scan, the final design will be exported as CAD natural files for direct manufacturing, CAE and any other post design applications.
