Miter Flange Corner Joining Issue

Hi guys

I am dealing with one job, not a big one but there is a flange feature that I am struggling with.

I need to make the same flange on 3 edges and they have to have all 45 ° ending and joining. ( Miter 1 is the right flange profile. )

I can manage the ends but I am struggling with the joint in the top left corner. Its a bit messy now and not what I need to have. I need 45 ° joining each flange.

the same like I have got on the first flange at the bottom.

I was gonna do the miter flange on all 3 edges at once but it says it can not be done on the top edge and I do not know why.

If I want to do that, It shows a little icon ,,Propagate,,.

Would you mind taking look at my part and see what you can do?

Good night and thank you to all of you

hei'ya Fred, see if this is of use for some ideas,

I think the issue is the two flanges are not geometrically true
to each other- one is perpendicular and the other tilted by the 25deg
I'ver modelled from a mold situation rather than a base flange
and used rips to control the surfaces
hope this helps dude- have a good'n kelef

  Hi Kelef,
  It looks perfect. I have to go tru your steps in detail to see what you have done.
  Your way is very different. Is this one of the ways that we can do when we do sheet metal work?
  Do we get the same flat sheet pattern size with all the bend lines as we normally get with standard sheet metal design?
  Again, thank you for showing me this way!!!!
  I am going to go tru it now to see what you have done....
  Thank you!!!

  Hi again Kelef,
  just a question, do I have to do the Rip Sketch on inside face of the flange only? I have noticed that if I do it on the outside edge, it never works right.
  Also, Created rip Sketches must be selected first is that correct? I was trying to select the bend edges first but SW was automatically selecting whatever ok by SW which was not what I needed.
  Thank you again

    g'day Fred, in this situation you need to remember SW always needs to know boundaries first,
    or you have to interupt the work flow by back editing/trim etc.
    the rip is active only on the surface drawn- as far as I know- I always treated that way
    I like to have all the rips as a single sketch/3d sketch and then select in the tree at that option
    the model I sent is an inverted mold so I can control surfaces, as you select the next flange you
    have to have the boundaries set/active or SW will select to major extents
    the bug here for the flange corner you are haveiing problems with is they are 2 different conditions
    1 at 90deg and going into 1 at 115deg
    you could of course do many different ways to get the result I did as an inverse mold
    a surfacer would produce the individual surfaces, and then convert to sheet metal
    you could possibley do a corner treatment by doing the flange ing in 3 steps
    and editing other ways that produce the same result-
    hope this helps dude- have a good'n kelef
