SolidWorks accepts files saved in STEP product data files (.stp, .step) and can use them for making new Solidworks technical files, which include assemblies (.sldasm). Possibly may also be done using a CAD translation software or through some 3rd party CAD/3D modeling software.

Convert from stp file format
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 stp to sldasm. 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.
