Here is thelink to the NI Controller on 3Dcontentcentral.com
I don't know the electronics in the kit. Do you have part numbers and manufacturers? I might be able to call them on Monday if they are SolidWorks customers and ask for files on your behalf.
I used a new technology in SolidWorks to save the NI Controller. I took the step model file from NI and confirmed with First CAD Library and then saved the assembly as a SolidWorks part. It is a single part with all extracted faces - much lighter in file size.
