Can someone please help me, I have the 2013-2014 Educational version of Soliworks and I am working on a project that involves using the SPLIT command under TOOLS and FEATURES. When I try to change the names of the split parts after cutting them, it will not let me save the parts and it keeps saying "invalid file name". I was able to let the program give the parts their default names and save them as Body1, Body2, etc. But that is not what I need to do for the project and when I am trying to save the assemby as a custom name it gives me the same "invalid file name" and will not let me save it, so I am unable to bypass it using the default names anyway. Any help will be very graciously appreciated.
