I'm very new to Solidworks. Just started a class at UCSD.  I have a part that is essentially a wheel. I would like to split it in half, to export to print on a 3D printer. To then print 2 copies and glue them together. I know how to export the STL etc.

What is the best process, to make sure I'm spliting (deleting half) of the wheel. perfectly in the center. Can anyone walk me through?

Thanks

I attached the file incase it matters.
