This conversion basically represents conversion of 3D models saved in ISO STEP product data files (.stp, .step) to one of the formats used by Parasolid (.x_b). It should be doable in several CAD programs or even some of the dedicated 3D modeling / conversion programs, some good choices are listed below.

The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned step to x_b. However, it is not perfect and sometimes can show results which are not really usable because of how certain programs work with files and the possible conversion is thus actually not possible at all.
