Adding draft to a curved surface

[PaulHalverson]

I'm trying to draft the highlighted surface in the picture below, puliing along the Z axis (blue arrow). The draft analyis shows that there is 0 desgrees of draft along the center of the highlighted surface (the red section). The draft command doesn't seem to handle curved surfaces too well so I'm sort of at a loss on how to accomplish this, ideas?

Hi! Drafting spline face could be tricky. If I were you, I would suppress (or delete) the curvy faces and then do the draft. After that, add the curvy faces back.

Thanks!

Hi Paul,

Are you allowed to move the parting line so that it splits the red section? If so, you might be able to add some material without having to rebuild the curvy face to make the part manufacturable, similar to what I've done on the right-hand-side of this simplified piece:

Paul,

I am a bit confused by the design intent. I am sorry if I misunderstood it. But, there is some inconsistency that I don't understand. The face of interest here is from Loft1, which is affected by FaceDraft2. But, the pulle direction used in FaceDraft2 is different from the one used in Draft Analysis 11. Why is that? Why do you need two perpendicular pull direcitons? Are you creating more than two mold pieces?

Thanks!

Thanks guys, I appreciate the input. The pull direction changed part way through the design and FaceDraft2 is a remanent of that.
I started over at the loft, got rid of FaceDraft2, and tinkered with the sketches used in the loft until I arrived at a parting line I liked so it's all good to go now.
Thanks again.
