The other thing i did was to create a flange wall in every sheet metal wall.
Ptc sheet metal flat vs flange.
Then you can show that axis in the drawing.
Information regarding the difference of flange and flat wall features for sheet metal.

This part is either coined or rolled with a hem tool.
Here is the basic explanation for the two sheet metal options.
The picture shows the part and the tool that is is formed on.
Information regarding the difference of flange and flat wall features for sheet metal.
That s what forms the gap is a rip is added the subtraction of.
The results should be similar.
This tutorial is part of a course.
In the formed section this happens three times so creo would have to remove two extra bend allowances to make the part flat.
In the primary corner this happens once.
Flange is improved in sheetmetal design.
I already have the flat pattern geometry including the flange.
It purely depends upon the shape of the part that decides which one to use.
Changing a bend with the constant flat length option selected.
Paul sobejko s suggestion is correct and to work through the reason each bend in sheet metal stretches the metal.
When modeling sheet metal you always have to be aware of the process used to fabricate the part.
The perimeter is curved and there are a lot of relief cuts in the part.
Flange wall gives you control over the cross section of the wall.
Edge treatment is improved when defining a flange feature.
Pro e showed to be very inconsistent here with this.
In creo if you use a form tool feature it will not account for the additional material in the flat pattern.
Constant flange length keeps the distance between the apex and the end of the wall fixed.
I did some iterations to get the numbers to match ie.
Below is the basic example of the flat and flanged walls.

Constant flat length ensures that the length of the unfolded wall is not changed.
Challenge modeling complex curved sheet metal flange also note that this is certainly not the highest level of integration.
