Gated Pattern Making

Hello,

I have done some searching on the subject but have not found any good tutorials on creating/designing permanent patterns (gated, split etc). I am interested in learning how to create a permanent aluminum pattern to be used to create impressions in sand molds. My question is, using the 3D models of finished or cast components how then do I model a permanent pattern?

If anyone has any insight or helpful direction I would appreciate it.

Thank you
