populating design table values w/ macro

I have dimensional values that I will use in multiple models.Iwould like to know of any thoughts on populating a design tablebydriving a macro.

My  sample external table may look something like this:
(there will be 40-50 size listings)

size        dim1        dim2        dim3
1            1.00            .50            5.00
2            2.00            .75            10.00
3             3.00           1.00          20.00


My desire is to setup a design table in the model and calldim1,2,3from the size attribute.
What this allows me to do is establish a dimensional standardforsize 1 across multiple models. It avoids the possibility ofhavingdifferent dimensions in different models for aparticularsize.

any thoughts are appreciated
