I am currently trying to apply draft to the side faces where the boundary surface pierces the part. The pull direction is perpendicular to "plane 1". How would you go about applying draft to the part on the specified faces so that the split line can follow the boundary surface.
In general, I used the surface representing the parting line to 'split' feature the solid geometry into "a" and "b" halves, and then used the parting line type draft feature to add the draft relative to plane1. Had to move some of the filleting to "after" the split and draft work to get it to flow correctly, and suppressed a bunch of stuff that was making life difficult for the parting line drafts. Here's a screenshot of the draft check set at 1 degree, and I uploaded your file with my tweaks. Hope this gets you close to what your after!

It may take some rework to the split line to get rid of undercuts. And sometimes you just end up with slight steps in parting lines (non-undercut, rather, shutoff areas where the parting line takes a particularly big step and draft angles going in opposite directions inherently give you little triangular sliver like surfaces at the PL). I'd have to see what you're referring to specifically and get a little more into the design intent as it relates to the casting of this part to be much more help. Save as much filleting as you can for after splitting and drafting , in general.
I'm glad you're liking the split command. It's huge, along with all the other 'multi-body' design tools. I'm always hacking models apart into multi-bodies and recombining them later to get geometry to work out just so.
Ah i got it. The split command is amazing.
Thank you so much. I have spent days trying to get this right.I did not know about the split feature. I have changed the draft angle to 3 but i cannot create a smooth parting surface for a tooling split. Any advice to help?
I take it back i am getting undercut on my model. I'm not sure how to split the model on the split line where the draft goes from positive to negative?
