Part families - Same pos number in part list?
Part families - Same pos number in part list?
(OP)
Hi all, I was wondering if someone could help.
When adding part families to a parts list (lets say I add 5 parts of a family to an assembly), I would like to have that all part family parts share the same pos number. I achieve showing only one of these parts in the drawing views using arrangements.
Right now, I leave the template part family member in the parts list with it's $~C string to call out automatic part numbers, but to have the other family members with the same pos number, I have to manually delete this string, then add a number (which I hate doing). Then, as soon as a part is deleted from the assembly, the pos order can be lost, or a number is missed out, or similar problems...
So, is there a way to make sure that part family members share the same pos number as the template part when added to assemblies/shown in parts lists?
many thanks in advance.

RE: Part families - Same pos number in part list?
If it's multiple copies of the SAME Part Family Member then the Parts List should work as you want it to. However, if these are DIFFERENT Members of the same Family then they are in reality, DIFFERENT part files themselves and as such, will EACH be assigned their own unique ID/POS number.

RE: Part families - Same pos number in part list?
I'm curious about a couple of things, when considering that the drawing views only show one of the family members using arrangements.
1. What is the standard practice for adding balloons/pos numbers for parts that aren't actually shown in the drawing views?
2. How is the scenario described in my first post handled by teamcenter? I'm very curious about this, as the company is currently trying to implement teamcenter (currently I work without teamcenter).
Many thanks again.

But I am still very curious about common/other people's practices when it comes to position numbers for different part family members in a parts list. Is it normal to give each part family member a different position number (in my head, this makes more sense)? Then, when adding balloons to the drawing views, where only one of the part family members is shown (the template for example), what happens with the balloons for the other part family members that are not shown? Do they just not get added to the drawing views?
Thanks!

So a final question, what about balloons for the 'other' family members when shown on an assembly drawing with a matrix for assembly configurations. Does anyone add these to the drawing views, or do they just get left out of the views?
For example, imagine an assembly consisting of two parts (one common part and five part family members) and five different configurations, hence a drawing with a parts list containing six parts, and a drawing view showing only one configuration. On the assembly drawing view, I would first add a balloon for pos 1, but then what about the positions 2-6? Is it best/common practice to add a balloon for pos 2, then not add balloons for pos 3-6, or perhaps stack the pos 3-6 next to the pos 2 balloon (this is what I had done at a previous company I had worked for)?
Thanks again

RE: Part families - Same pos number in part list?
I totally agree with you, each part family member should be treated as if they are made from scratch, and that they are not special. But because the company wants all family members to share a common pos id, I was mainly wondering if this was done by anyone else, or how it was normally done in NX (or any other system).
I'll post a basic assembly drawing on Monday just to show how I have been told to create assembly drawings at the current company.
Have a great weekend.
RE: Part families - Same pos number in part list?
The second shows how NX does it automatically by giving each part a different pos number (coming in the next post, as it should be). However, I am just still curious how others out there in the engineering world deal with drawings like this. I would imagine everyone does it as NX does (the normal way) and gives each part a unique pos number, but then how are the other part numbers marked on the drawing, when they are not included in the views?
Thanks in advance
