GW3Dfeatures includes the ability to create blended surfaces and curves with 3rd order continuity (G3). This makes it possible to blend surfaces and curves so that the rate of change of curvature is maintained from one surface to the next.
GW3Dfeatures can create spine-driven entities. Spines allow additional control over the creation of sweep surfaces, blend surfaces, and the offset curves.
The GW3Dfeatures user interface is identical to menus in SOLIDWORKS in their look and user interaction. This makes it easy to learn GW3D and gives it a familiar look and feel.
