Robert,

There are a few parametric modelers that are in common use, SolidWorks, Pro Engineer, Unigraphics (now Siemens). I only have SolidWorks myself, and it seems SolidWorks files are generally well accepted. I would hesitate to call any one application the standard though.

I really like that FormZ can work equally well with meshes and nurbs surfaces, and I miss that in SolidWorks.
