Uhh, parametric models are almost inevitably NOT going to be OpenSCAD. Basically no one uses OpenSCAD in industry. The Parasolid kernel is the most widely used, but Autodesk Inventor and Pro/E both have their own parametric model kernels as well.
Sorta depends on where you take your sample, doesn’t it? Go look around Thingiverse and see how many .x_t and .x_b files you find versus how many .scad.
