What formats of the files can Premium Parts accept?

We can accept most of the 3D file formats like SolidWorks (.sldprt)/ ProE(.prt) / IGES(.igs) / STEP (.stp) / Parasolid (.x_t)/.stl. We can also use 2D drawing (.pdf) for quote against the parts with simple structure. All the other files formats are not listed above but can be read in SolidWorks/ProE/UG will be also fine for us.
