HELP PLEASE !!!!!!!!!!!! with Draft/Taper NX9 - Gonna Put My Fist Through The Screen !!!!!!!!!!!!

HELP PLEASE !!!!!!!!!!!! with Draft/Taper NX9 - Gonna Put My Fist Through The Screen !!!!!!!!!!!!

(OP)
OMG - I'm on the verge of putting my fist through the monitor. I'm trying to place a simple draft along the edge in red below. Draft direction is shown via the vector. Preview shows up fine as you can see. But when click apply, I get the fail message. Even using draft from surfaces, preview shows up fine, but fails when I apply. Even if the angle is just 1 degree, same thing, preview is fine but fails after applying GGGGGRRRRRRRRRRRR!!!!!!!!!!!!!! I've been using NX since 1999 as an Automotive engineer, so this is not something new to me. I swear, since NX8 or NX7, the draft function has gotten so friggin volatile.

A thing I find odd is that on the top pic I see vertical lines on the face (in the preview?) but on the bottom pic they are gone.
Why would that be?

RE: HELP PLEASE !!!!!!!!!!!! with Draft/Taper NX9 - Gonna Put My Fist Through The Screen !!!!!!!!!!!!

(OP)
That's from a crap load of tweaking to the edge and the face trying to get it to taper. Like delete edge and a bunch of synchronous modeling operations. That likely made the edge un-smooth. Forgot to remove them. But the original face and edge did not produce any of those vertical lines during the preview and still failed when I clicked applied.

Did you try the Synchronous modeling Move Face? In there you can also put an angle.

Offest the surfaces and apply the draft from the bottom up? Delete the top fillet, try to draft, then re apply the fillet? Put the draft into the extrude,sweep or how ever you developed this feature. Could up load the local area of the part with the rest cut away? Many good people here may be able to apply their own magic.

RE: HELP PLEASE !!!!!!!!!!!! with Draft/Taper NX9 - Gonna Put My Fist Through The Screen !!!!!!!!!!!!

I agree that, in the last few releases, the draft command doesn't seem to be as robust as it used to be. Same goes for the edge blend and face blend commands.

When a "draft from edge" fails, the first thing I do is switch to single edge selection and apply the draft to one edge. If that works, pick another and update the draft feature. Repeat until it fails. Sometimes knowing which edge causes the failure will give a clue as to what went wrong. Other times, you can get the desired result by picking certain edges rather than the entire chain. If the face you want to draft is a B-surface and the edge is a "tolerant edge", it may help to simplify the geometry before attempting to apply the draft.

Occasionally, nothing seems to work and I end up creating my own draft surface, usually with the swept command. I hate doing that when it seems like a draft feature should work.

Is it possible to make a parasolid of your current part, cut away on it so only the about region is there, and then post it ?
Make sure the parameters are removed before posting it.

RE: HELP PLEASE !!!!!!!!!!!! with Draft/Taper NX9 - Gonna Put My Fist Through The Screen !!!!!!!!!!!!

you have tried both the Isocline and the true draft ? I have seen quite many cases where one of the two worked but not the other.
I think that the resulting geometry is quite the same in most cases.
