Create Flat Patter from a Lofted Flange (Transition)

[matt.hansen]

Good Afternoon All,

I have a large lofted flange made up from 3/8" Plate steel, set to be formed with a pressbrake, however I need to get flat patterns made so the object can be cut out on a CNC plasma table. I cannot get a flat pattern to generate, even though I have created a cut in the lofted object so its not continuous. I would appreciate if someone could look at my file and correct it or get me .dxf flat patterns. Please see attached F3D file. Thanks!

I have not looked at the file, but did you use the sheet metal Lofted Flange or did you use solid or surface Loft?

Does your rip go all the way through the flange?

Why does Sketch 3 repeat the hole diameter dimension 7 times?

Is the sketch fully defined?

Why does Transition component Sketch1 repeat circle diameter 7 times?  

Would a Rectangular Pattern or Equal (=) constraints be more efficient for editing?

@matt.hansen 

I think I would trim Sketch1 and 2 such that the Rip is created in the process of creating the Lofted Flange.

You are going to have to make some changes to your design.

See Attached file...

Im impressed you were able to get it flat? do you have a design recommendation?

[matt.hansen]

@TheCADWhisperer could you send me that flat pattern with the issues? I still can't even get mine to unfold LOL
