I am new to solid works actually going to tstart classes next month.   I have been following you here in the mold section becuase I build molds and hope to be able to design them one day, I have done a few simple straight part lines, and followed the Tutorial here and in Matt Lombards assembly book,  I have also tried to follow you guys on the form disscusions.  But here is a part similar to one we mold and I have cut the parts on the cnc for this, But I have yet to figure out how I would design it.  This is just a mock up of the part not the real part. I would like to see how someone would do the splits and make the shutoff surfaces.. and the 4 holes have pins that will press in them.
