how to convert a decimal numeric dimension to a fraction in an ebom drawing table

I am trying to convert a decimal numeric dimension to a fraction in an ebom drawing table. I have already added a parameter to the dimension and I am able to reference the parameter in the table. I don't want to convert the dimension in the model, only on the drawing table. How would I do that?

    Hi all,

    John,

    You can add a relation block to implement a 'repeated multiplication by 2' algorithm.

    It is kind of ugly code, but with the limited pro/relations syntax we have to use what we could.

    Something like this:

    test =7/64 /* replace 7/64 with dimension symbol, works for positive numbers

    test0=floor(test)

    test2 = mod(test,1) *2

    if floor(test2) > 0
    first=1
    denomiator = 2
    numerator = 1
    else
    first = 0
    endif

    test4 = mod( test2, 1) * 2
    if floor(test4) > 0
    second=1
    denomiator = 4
    numerator = 1*second + 2*first
    else
    second = 0
    endif

    test8 = mod( test4, 1) * 2
    if floor(test8) > 0
    third=1
    denomiator = 8
    numerator = 1*third + 2*second + 4*first
    else
    third = 0
    endif

    test16 = mod( test8, 1) * 2
    if floor(test16) > 0
    fourth=1
    denomiator = 16
    numerator = 1 * fourth + 2*third + 4*second + 8*first
    else
    fourth = 0
    endif

    test32 = mod( test16, 1) * 2
    if floor(test32) > 0
    fifth=1
    denomiator = 32
    numerator = 1*fifth + 2*fourth + 4*third + 8*second + 16*first
    else
    fifth = 0
    endif

    test64 = mod( test32, 1) * 2
    if floor(test64) > 0
    sixth=1
    denomiator = 64
    numerator = 1*sixth + 2*fifth + 4*fourth + 8*third + 16*second + 32*first
    else
    sixth = 0
    endif

    result = itos( test0) + "-" + itos( numerator) + "/" + itos(denominator) /* string representation of fractional number

    HIH.

    Feliks.
