The native CAD for Robot Studio is ACIS (.sat). You will need to convert the STEP (.stp) to .sat. You could also purchase through ABB a .stp to .sat CAD Converter. ---

Step can be imported directly if you have license for it. What happens when you try? ---

Same problem here. Sometimes ACIS also didn’t work. You can try to convert with CAD Exchanger Trial.
