The other thing i did was to create a flange wall in every sheet metal wall.
Ptc sheet metal flat vs flange.
In the primary corner this happens once.
Constant flat length ensures that the length of the unfolded wall is not changed.
Changing a bend with the constant flange length option selected.
A ptc technical support account manager tsam is your company s personal advocate for leveraging the.
That s what forms the gap is a rip is added the subtraction of.
Constant flange length keeps the distance between the apex and the end of the wall fixed.
Edge treatment is improved when defining a flange feature.
Here is the basic explanation for the two sheet metal options.
Changing a bend with the constant flat length option selected.

Hi everyone i m trying to model a sheet metal part with a complex flange around its perimeter.
Flat wall gives you control over the profile of the wall.

Flange wall gives you control over the cross section of the wall.
72 1 8 is slight short 5 72 may not be exact.
This tutorial is part of a course.
I already have the flat pattern geometry including the flange.
Paul sobejko s suggestion is correct and to work through the reason each bend in sheet metal stretches the metal.
Then you can show that axis in the drawing.
Flat patterns deformation allowance bend tables working in both flat and as designed states and full associativity between part drawing and flat state.
Information regarding the difference of flange and flat wall features for sheet metal.
In the formed section this happens three times so creo would have to remove two extra bend allowances to make the part flat.
The picture shows the part and the tool that is is formed on.
Flange is improved in sheetmetal design.
Specifically topics covered include.
When modeling sheet metal you always have to be aware of the process used to fabricate the part.
The results should be similar.
It purely depends upon the shape of the part that decides which one to use.
In creo if you use a form tool feature it will not account for the additional material in the flat pattern.
The perimeter is curved and there are a lot of relief cuts in the part.
Pro e showed to be very inconsistent here with this.
Sorry to say but i thought this was a cool feature but it came totally useless to me as i cannot show the bending axis as in a regular flange wall.
Below is the basic example of the flat and flanged walls.
Challenge modeling complex curved sheet metal flange also note that this is certainly not the highest level of integration.
This part is either coined or rolled with a hem tool.
