New to Strata 3D CX is an all new modeling system called PolySpline modeling.
PolySpline modeling consists of two different tools that can be used together, or in conjunction, to produce complex organic and mechanical shapes in Strata 3D. The first addition is a powerful new polygonal editor that lets you extrude, bevel, rotate and scale each face, edge, or vertice of a 3D object. Once you have a rough approximation of the shape, you then apply the second tool: subdivide.

Subdividing a polygonal shape in Strata smooths out all the rough edges into a flowing, seamless shape. You can go back to the rough cage and continue to model while whatching the smoothed version update in real time.
