sldprt to sldasm conversion describes the process of making new assembly files (.sldasm) from individual part files (.sldprt) using SolidWorks. This can be done with SolidWorks and making assembly files is a core function of the software, as these are containers that contain everything that is need to view and work with the individual parts.
The same should also be doable with any other 3D modeling solution that supports SolidWorks files.
