How to create a variable-pitch helical sweep in Designmodeler (v11.0)
 

Does anyone know whether it is possible to create a variable pitch helical-sweep in Designmodeler (Ansys v11.0)? And if so, is it possible to parameterize the pitch?

I know how to create a helical sweep, but have not been able to find out how to vary the pitch. I'm aware that Solidworks and other CAD platforms are readily capable of doing this, but would like to do the operation in Designmodeler.

Thanks in advance for your help!
