ugly twisted sweep
ugly twisted sweep
(OP)
Whenever I try to do a sweep from a rectangular shape into a round shape it always twists the result.
What's the easiest way to get a smooth result? I'm using UG NX4.

match the lines of the rectangle.

What is the advantage of a through curve feature over a swept feature in this case?

RE: ugly twisted sweep
I'm working on something similar so the .prt you posted was especially helpful. I have a couple of questions though:
1.Breaking the arc ahead of time is how I used to do it in lesser systems where you couldn't manipulate alignment on the fly. Why do prefer this. It seems to lock you in.(Not quarreling with results, it looks nice.)
2. How did you construct dashed lines that determined break points on arcs?
Thanks

I'm happy to help but I'm a bit concerned about the nature of what you've posted here. It may be appropriate to take any further assistance on this one out of the public domain. It can be done in more or less similar fashion to the previous example with some refinements. Perhaps you should contact me directly through my website.

RE: ugly twisted sweep
Thanks for the response. I generally think of the through curve feature in terms of generating sheet bodies, I often forget it can do solids as well (as the swept command can).
RE: ugly twisted sweep
Not quite sure what I posted that was inappropriate. I'm not looking for a level of help that would require a contractor / consultant. My understanding of the forum is that it's a place
to ask questions and pose problems.
Thanks just the same.

Because I cropped the title block I thought it might be ok.
I'll be more careful next time.
Thanks for tip.

RE: ugly twisted sweep
I found Through Curve on the NX menu, but the resulting dialog box is very confusing. So I searched the help library for "Through Curve" & got 50 results, none of which seem to be related to through curves.
I'm admittedly biased, coming from a SolidWorks background, but it seems simple tasks are much more complicated in UG NX4. We're getting NX6 at the end of next year. Is that interface any cleaner or more intuitive?
RE: ugly twisted sweep
I moved from NX2 to NX6 and the dialog boxes were much improved. I imagine there will be improvement from NX4 to NX6, but probably not as big a leap. I especially like trying out different options in the freeform commands before hitting OK. Previously, editing such parameters was much more cumbersome (sometimes involving deleting the feature and starting over).
RE: ugly twisted sweep
I have attached a copy of the example in NX-3. That ought to cover most users on the forum.
Ray,
I didn't want to mention your error for your sake. I can see that the example in question is not much more complex than the earlier ones described within this topic. I was merely going to suggest that you construct a file and send into to me NOT in the public domain, whereupon if I can assist quickly then I will and if I couldn't then I'd let you know why.
You are of course welcome to offer projects for quotation since I'm certain we'd be more than competitive, but the assumption that you were offered anything OTHER than help and discretion is incorrect.

You're right. I apologize, and thanks for bringing it to my attention.

RE: ugly twisted sweep
Thanks for posting the sample. It looks like you created 2 solids then connected them with 4 lines, then used the "Through Curve" feature to create the transition shape, and finally united the 3 solids. Is this correct?
