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

[jbennett]

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.
