Create 2D sketches, surfaces and solids, and PolyNURBS.
Global References
Global references are the global origin, axes, and planes shown in the modeling window. They can be helpful when creating and defining your model.
Sketching
Create and edit 2D parametric sketch geometry.
Geometry
Create and modify parametric surfaces and solids.
PolyNURBS
Create free-form solid geometry that is smooth and continuous.
