Flat pattern tube
Flat pattern tube
(OP)
Hy to all,
I have problem with one part, NX doesn't allow command "FLAT PATTERN".
Pipe starts with one diameter and ends with bigger and I make it with extrude + draft feature. Then I add a thickness of 1.5mm, and I use command CONVERT TO SHEET METAL.
But when I try to flatten the part, NX popup with "UNABLE TO CREATE BODY"
Can someone help me with this issue/part?
Thanks

RE: Flat pattern tube
It seems to me, that it happens because you're trying to unfold a cone. I can offer you to unfold inner or outer surface using Fabric flat pattern, create an bounding surface and thicken it by 1.5 millimeters then. Looks a bit weird, but supposed to deliver a result.
Unwrap a section curves would also give good results.
RE: Flat pattern tube
thanks on answer. I try it with FABRIC FT, but doesn't give me correct dimension. Exactly, I need to draw this model, and flat pattern dimension should be same as on attachment PDF (see it).
Second, I have to made this cutout and holes, which is possible only if I draw 3D, make FT and draw a cutouts on FLAT SOLID.
RE: Flat pattern tube
Are the flat dimensions correct?

I made it finally, difference in flat patter shape is only 0.6 mm according to original drawing, which is good for me.
Thanks for your help
RE: Flat pattern tube
See attached file for solution.
The method:
- Create sketches at each end of tube
- Create ruled surface between them
- Thicken to desired material thickness
- Change to Sheet Metal application
- Convert to Sheet Metal
- Create flat pattern.
