Swept in NX6

Swept in NX6

Swept in NX6

(OP)
Hello everyone!


I'm having a little trouble with the Swept tool in NX6. Ok, there's the problem: I try to make a swept between two diferent sections (i.e. circle & hexagon) and then it makes the swept but it comes to be twisted. Is there a way to not to get the swept twisted?

I fix this using "alignment method" by points, but when it comes to be more complex sections is really annoying.

Can anyone help me?

Thanks

I upload an image of my "twisted swept"

 

RE: Swept in NX6

Attached is an NX 6.0 example of a model similar to your image using the Surface -> Through Curves method of construction.  Perhaps this might prove to be easier to use.

Thanks John, "through curves" is easier, I'll use it instead of "swept" when I could. But it keeps getting twisted. In your file an hexagon vertex is oriented "right" while mine is "up"

JCBcad, unfortunately I couldn't open your file because I have NX6, but I understand, due to the default start point of the circle is in the right, and my hexagon doesn't have any coincident start point, my swept get twisted. So I need to "create" a start point in the upper cuadrant of my circle.

Both of you, thanks a lot

RE: Swept in NX6

Use the "Specify Origin Curve Option" to select a different origin curve for the hex end.  It should be the one closest to the direction arrow shown for the circular end.  Double click the direction arrow on the hex end if it running in the opposite direction on the circular end direction curve.

 

RE: Swept in NX6

Looks like I misread your twist problem when following John's example.

Another option to fix the twist would be to change the horizontal reference of you circular sketch by 90 degrees.  This will put the start point of the circle in line with one of the hex points, then you can use the select origin curve on the hex end to make things line up properly.

RE: Swept in NX6

Change the 'Alignment' option to 'By Points' and you can literally drag arbitrary alignment points around the profiles until you get the desired transition.  Note that while the 'By Points' option will provide you the ability to align the profiles, it's still best if the respective starting points of the profiles are initially aligned as close as possible.
