Calculating length of a wire product

Discussion in 'Pro/Engineer & Creo Elements/Pro' started by Bertil Rogmark, Dec 12, 2009.

  1. Take a U-shaped wire, bent from 10 mm O.D. stainless steel.
    You model it as a swept extrusion or a pipe (solid) and when finished,
    you calculate the required length to cut from your stock material, either
    by doing the geometry math yourself or by creating an evalute feature.
    Either way you end up with the same answer, 3 straight lengths and 2 quarter

    If you model the same part but now as a square (10x10 mm) section and then
    declare it as
    a sheetmetal part you can get the required length by using a flat pattern
    When a sheet metal part is bent, it stretches and therefore, which ProE
    recognizes, the total
    length required is less than the "geometrical answer" above.
    Its obvious that in reality, the wire stretches when bent just like a strip
    of sheeet metal and that
    therefore the second smaller answer is correct.

    Now, does anybody know a way of getting a "flat pattern" answer without
    having to redo the part
    in square form. This redo can get complicated if there are more bends to the
    wire that are not all in the same

    How does one "killfile" a poster (I assume this results in you not
    being forwarded anything by them any more?) ?
    I am poking around the google group site here and not seeing a switch
    that looks like that...

    So tired of sifting through all this yelling John Banquer chaff to get
    the good bits of advice out

  4. Killfile is a generic term meaning use whatever filter your newsreader
    has to delete the garbage posts. JB is very easy because he posts under
    the same user name (newsreader softwares still aren't sharp enough to
    filter based on the stupidity of the content)

    I'm using Mozilla Thunderbird and it's pretty easy to set up a Filter to
    delete particular messages. I poked around google groups and found no
    such features. However, I did flag all of JB's threads as spam, so if
    others do the same maybe we can collectively vote the threads into
    oblivion or something. :)
