NX10 sheet metal puzzle

[Karlis]

Hi all,
I have attached a parasolid file. It was created with SolidWorks 2016 using complex side route to sheet metal because the SW sheet metal features were not advanced enough to perform this in a way that it could be flat patterned. Can anyone please try and recreate this using NX sheet metal? Please note that the part is slightly tapered.
Thanks in advance!

Have I really stumbled upon something the all mighty NX is unable to do?

Hi Karlis

I posted a part using nx85
its not exactly but is very close to your parasolid

using sheet metal loft on 2 arcs

I have attached a picture with a very obvious problem to your example. This is also the reason why SolidWorks failed to create this.
The middle section of the loft feature is skewed inwards. It is not tapered anymore.

 

[Ehaviv]

Yes the skewed inwards is big if the openings points of the circles
are far from the aliged state and small if are close to the aligned state

If you need it not aligned I guess it is impossible.

The part I need to design has this twist angle close to 180 degrees. So I guess that makes me proud, to have discovered something that I have made with my own hands with very little effort, but it is impossible to model it with Siemens PLM NX10!

This posted part is a version of the previous one but
with convert solid to sheet metal visualy I do not see
a skewed shape

What is the catch? This parasolid model is easy to model... So what I am missing?
extrude with draft, make line with neded angle, project it, make profile for cut-out, swept it with orientation set to face normals, subtract it... this is like 2 minutes... so what I am missing here.

 

[Karlis]

IvanNX, well you are missing the sheet metal part. It has to be sheet metal in order to pull a valid flat pattern out of it. When I tried converting the solid to sheet, I was told it is impossible because there are no linear edges to show.

Here is a older previous thread that may help you.

Ok, now I understand. I am not daily sheet metal user so I am "leaving" the conversation.
