With this AutoCAD add-on you can create mathematical curves.
Curves can be defined as explicit, parametric or polar functions.
Function's formula can also be changed dynamically by changing
parameter 'p' value(parametric modeling).
Use standard AutoCAD commands(revolve, extrude, ...) to create
solids and surfaces from these mathematical functions.

MathShapesPro2X is an useful tool for designers who need precise
analytical definition of curves(surfaces, solids) in their drawings.
