The two concepts could however easily coexist in FreeCAD. Watch an introduction to direct modeling on Direct modeling, often presented as the opposite of parametric modeling, allows to graphically move vertices, push or pull faces and edges to modify the geometry of an object. This mix of operation and object is called a feature. Each step is at the same time a tool/operation, and a geometrical object, resulting from that operation. ![]() ![]() FreeCADs is a feature-based parametric modeling system, hence different modeling steps depend on one or multiple previous steps.
