NX 5 sweep normal to a surafce

NX 5 sweep normal to a surafce

NX 5 sweep normal to a surafce

(OP)
I am sweeping an extruded section for an upper door molding used on a vehicle (not named).
I received a step file of the door created from sewn sheets to use as my reference data from my customer. When I extracted sheets to use as my normal orientation for sweeping my extruded section, I noticed a mis-match in two of the adjoining surfaces in the Header/B-pillar area. Both front and rear door have this condition causing a "gull wing" condition at the rear edge of the front door and the front edge of the rear door.  After highlighting this to the customer, it was explained to me these two surfaces are not tangent, nor are they intended to be. I used an edge of the original door data to create my guide line,after analyzing it, smoothed out the curve where the two adjoining surfaces met. Without having to rebuild the customers surface data to use as my normal orientation, is there something I can do to eliminate the undesirable highlight where the two surfaces meet when the section is met?

Any insight as how to solve this issue is appreciated.

It is really hard to understand without seeing something in terms of pictures of the problem.

RE: NX 5 sweep normal to a surafce

there are several ways to do this,
I think you should use law extension in that case.
hih

If I understand correctly, your guide strings look something like the attached jpg. If your customer knows it is not tangent and is not intended to be, I would show them what the result is going to be based on their geometry. They may change their geometry or allow you to deviate from it a certain amount.

Yes, that is the idea, however it is a bit crisper of a transistion than what is shown in the jpeg (a sharp edge, kink if you will). It is in two directions, X,Y and X,Z. I made some screen shots of the area in question and passed that along to the customer. You're right, the customer was unaware of the severity of this condition and are in the midst of changing it.  I also used a law curve as suggested deviating from the surface to create a much smoother continuous surface in that area. I requested the Body Side aperture to confirm design intent.
This is the first time I used this forum and thankful for all your valuable input.
