ProSurf is a NURB surface modeler with functions like trimming, sweeping, lofting, extruding, 2D shapes, and 3D solids. Hydrostatics, stability, and resistance calculations are available. There is a set of import and export file options, like DXF, IGES and TXT formats. You can also read and write hull offsets formats, like SHCP, GHS, and NWS.

PTC Creo is a scalable, interoperable suite of product design software utilizing 2D CAD, 3D CAD, parametric and direct modeling.

Rhino can create, edit, analyze, document, render, animate, and translate NURBS curves, surfaces, and solids, point clouds, and polygon meshes. There are no limits on complexity, degree, or size. No special hardware is needed. No maintenance fees.

SolidThinking Evolve uses NURBS geometry definition methods with direct modeling approach. It provides organic surface modeling and parametric control on surfaces and solids with history feature.
