I can generate the transition, but the problem is when I try to create its flat pattern to manufacturate.

I can create flat patterns of flanges or pipe elbows, but not with this transition.

Is there any way or tutorial to do it?

Thanks in advance!

What version of NX are you running?

Hi,

I am interested on how to create the square to round and flatten it as well.

Many thanks for any tips!

John

I can't get it to work in NX 8.5 but I was able to do it using NX 9.0, as shown below. Even then, it's a non-trivial solution, however I've attached the part file (along with a copy of the image) in case anyone with NX 9.0 would like to look at my approach.

JonhRBarker, can you write every step to get to this result??

Maybe I am not modeling this patter properly. I use through curves.

Also what function do you use to unbend it? And the following.

Thanks in advance!

Mine is made completely using Sheet Metal Features, basically Contour Flanges and Base Pads. If all you wanted was the solid body, there are much easier ways to go, but if you want to be able to flatten it, then you have to really go the Sheet Metal route. The big difference between NX 8.5 and NX 9.0, in this example, is that I had to create the portions of the transition as separate bodies, albeit Sheet Metal features. Unfortuantely, in NX 8.5 there is no way to unite these together and still have the Sheet Metal module consider the model to be 'flattenable'. In NX 9.0 we added a specific 'Unite' function to the Sheet Metal set of functions so that you can now use a piece-wise approach to creating a Sheet Metal part that can still be 'flattened' after the pieces have been United together.

JonhRBaker, so apparently there is no way to do it with NX 8.5??

Thanks!

Would it be possible/easier with the "aerospace sheet metal" module?

aerospace sheet metal is a module in NX available at added cost
but it is possible that you have it in your NX bundle and don't realize it

I would check ir, but, do you know if there is any way to do it with the basic license?

Thanks!

My expectation is that with a BASIC license, you should be able to accomplish something as BASIC as this square-to-round flat pattern.

This is Sheet Metal 101, y'all.

Are my expectations too high?

[green]To the Toolmaker, your nice little cartoon drawing of your glass looks cool, but your solid model sucks. Do you want me to fix it, or are you going to take all week to get it back to me so I can get some work done?[/green]

You can, starting with NX 9.0, which has been available for well over a year now.

I need to apologize as I made this problem way more complicated than it needed to be. After going back and looking at the options available to me I realized that the NX Sheet Metal software was a lot more powerful and accommodating then even I was aware of, including NX 8.5. What I discovered was that I actually was able to create the round-to-square transition 'duct' using NX 8.5 and I did it using only EIGHT features (two of which are Datums and two of which are Sketches). I've attached the NX 8.5 part model. Note that the only real issue is that I had to leave the duct in two halves, flatten each one and then Unite these bodies to form the final flat solid.

Note that in NX 9.0 I can actually get a single model of the 'duct' that can be flattened, and I can do it with ONE LESS feature, seven in total (again, two of which are Datums and two of which are Sketches).

Hi John,

Could you give some insight on how you created the square to round shape? A video perhaps?

Sorry for being behind in my design capabilities.

Thank you

John

Attached is a video showing how to create this transition 'duct' using the NX 8.5 basic Sheet Metal application.
