Conversion to Solidworks Part from OBJ

Hi CAD-ists,
I've got this quite large model in several formats except Solidworks.
I need it converted to a Solidworks part, but doing so keeps getting my Solidworks crashed, after a very long waiting time.
Can someone help me with this conversion, please?
I don't want STL format as I am not able to move files in that format to Solidworks Drawings.
I just need to hover the surfaces, at the least.
