I think I'd use complex profiles, as described in this thread:

I think he/she means a spaceframe like the attached image, but curved instead of straight.

For a parametric solution, a GDL based library part will do what you want.

There isn't one included in ArchiCAD as standard, so you may need to code one yourself, or buy an existing one (if there is one available) from somewhere like Objects Online, or commission one of the GDL experts to make you a custom version.

There some examples in the GDL Cookbook 4.0 from page 149 onwards if you wanted to get into coding but be aware it gets quite complicated for the beginner! The PDF download is found here - http://www.archicad.ca/?p=84

For a non-parametric solution try building up individual components on the floor plan using complex profiled beams and walls , then saving them as an object. You may find Ralphs' OBJECTiVE tool useful for bending and rotating the individual members.

Good luck!
