Simple section sweep issues
Simple section sweep issues
(OP)
Platform: NX4
I am trying to create a simple sweep from a .18" circle to a .10" circle using a curve between the two center points as a guide. (i.e. I am making a converging duct)
Issue 1: The resulting shape is not linear
The little guide arrows point different directions, which means the shape is being twisted, but I am not sure why this matters but it does.
Would someone please explain the correct way to use the NX4 sweep command. I have gone through several tutorials on the net and am convinced that no one understands how this command works.
Any help would be appreciated.

RE: Simple section sweep issues
I think this perception comes from the fact that it is a very powerful command with lots of options to choose from. The tutorials you saw probably all used different options from each other and none were precisely the options you needed for your application. There are multiple ways to get the desired effect within this one command. The classic example is sweeping a shape along a helical path; using 1 guide and the default options will result in the shape 'twisting' along the path. This can be fixed by using multiple guides or using the 'vector direction' alignment method.
Spend some time in the help files while you play with the options and post questions as needed. You will find that swept is a powerful and useful command to have in your bag of tricks.

Using cubic interpolation you may be able to achieve simple tangency with adjacent geometry which supplies a pretty good reason for having the two methods.
