The picture shows the part and the tool that is is formed on. Edge treatment is improved when defining a flange feature. 72 1 8 is slight short 5 72 may not be exact. I already have the flat pattern geometry including the flange.

Then you can show that axis in the drawing. In the formed section this happens three times so creo would have to remove two extra bend allowances to make the part flat. In creo if you use a form tool feature it will not account for the additional material in the flat pattern. Below is the basic example of the flat and flanged walls.

Constant flange length keeps the distance between the apex and the end of the wall fixed. Specifically topics covered include. Constant flat length ensures that the length of the unfolded wall is not changed. Hi everyone i m trying to model a sheet metal part with a complex flange around its perimeter.

Flange is improved in sheetmetal design. The results should be similar. Views 671 views difficulty level introductory jim barrett smith ptc. Flat wall gives you control over the profile of the wall.

It purely depends upon the shape of the part that decides which one to use. Flat patterns deformation allowance bend tables working in both flat and as designed states and full associativity between part drawing and flat state. The other thing i did was to create a flange wall in every sheet metal wall. 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.

Here is the basic explanation for the two sheet metal options. Changing a bend with the constant flange length option selected. Information regarding the difference of flange and flat wall features for sheet metal. The perimeter is curved and there are a lot of relief cuts in the part.

This part is either coined or rolled with a hem tool. Paul sobejko s suggestion is correct and to work through the reason each bend in sheet metal stretches the metal. A ptc technical support account manager tsam is your company s personal advocate for leveraging the. I did some iterations to get the numbers to match ie.

Pro e showed to be very inconsistent here with this. That s what forms the gap is a rip is added the subtraction of. Challenge modeling complex curved sheet metal flange also note that this is certainly not the highest level of integration.
