Hi all, I am new here and I am having some problems splitting a tool in Solidworks 2007. The part has seemingly no flat surfaces, but thankfully the company we are making it for gave us a plane with the direction of pull. The difficulty is because I am somewhat new at mold making in Solidworks I am not sure if there is something I am doing wrong, but it's not splitting. I get the error "Cannot knit sheets together." I put my own shutoff surfaces in where it was necessary and included those surfaces in the Core and Cavity folders. Also, because of the complex geometry I made my own parting surface which could also prove to be a problem. This part has been very difficult and frustrating any help would be very much appreciated! Thank you.
