Showing part families on assembly drawings

[201181]

Hi all, I hope I have posted this in the correct forum.

At my current place of work, I have been using part families more than ever before, and one of my main task is to produce models and drawings of components, where many of which are part family based (I am currently using NX 7.5). These parts are fairly simple (for example, a shaft with a common diameter, but comes in different lengths).

It is also common to create part family assemblies, where a product may come in variations, which each contain certain parts. All parts for all variations of a product are included into the parts list on the drawing, then a matrix system is used to show which parts belong to which assembly variation. I imagine this all sounds quite normal so far...

My question is, when adding balloons and working with position numbers, what do the rest of you out there do on your drawings? If the assembly drawing has all family members of the shaft example included on it, do they all have the same position number or different numbers?

I hope it's a simple question, and I am very interested to hear what is or isn't normal in these situations. Many thanks in advance

We generally only draw one version and just use the table to list the variations. The drawing has a item number balloon and the table shows the part number to be used in the assembly. Likewise for parts we only draw the generic and put the variable dimensions in a table.
