conical extrusion help.
(OP)
hi everybody,
i need some help or some tips. i'm just starting with NX3.
i'm trying to make a conical extrusion of a sketch that is quite complicated. i'm able to do it if the angle is less than 4 degrees but if i put more the feature is not possible any more.
is there another way of doing it?
If somebody could help me i'd appreciate.
thanks.

RE: conical extrusion help.
How much taper are you looking to add?
A few (untested) ideas:
If the taper makes the part larger, you may have features running into each other at angles greater than 4. If the taper makes the part smaller, some features may be disappearing before the end of the extrude. I'm not 100% sure that either of these conditions would cause an error, but I would not be surprised if they did.
You may want to save a copy of your file to experiment with and simplify your sketch until it will extrude. My guess is there is 1 or 2 features of your sketch that are causing the problem. I would try to simplify the sketch and see if I could add those features later.
RE: conical extrusion help.
I'm not sure what you mean by a conic extrusion, but if there is a conic in your sketch & it fails during the extrusion, again try removing the conic from the sketch & extruding. If it extrudes without the conic, then either blunt the conic by making the rho value smaller (rounder) or apply a conic face blend after the extrusion. You can create variable radius conic face blends, but that's a little more challenging than a variable radius circular blend in NX.
Hope this helps a little.

RE: conical extrusion help.
for info the taper make my part larger
I will try to remove radius from my sketch then extrude with an angle and then add a radius...
i will tell you what happen.
