Drawing Tree Standards

Drawing Tree Standards

Drawing Tree Standards

(OP)
Is anyone aware of any standards for creating drawing trees?  Currently the drawing tree structure is dictated by our project managers and they all end up being different.  I'd like to be able to standardize them somehow.

Thanks,
Bob

RE: Drawing Tree Standards

I've never heard the term "drawing tree", can you please educate me?

RE: Drawing Tree Standards

Well I was going to tell you to look in ASME Y14.24-1999 Types And Applications Of Engineering Drawings, but I took a quick look and couldn't see it listed as a type of drawing.  However, figure 1 is kind of an example of a typical family tree, even though it's just explaining drawing structure within a pack.

bashcraft,

   Is there any reason why your drawing tree data would be defined by anything other than the parts lists?  

   I have seen similar problems with assembly trees, but these are due to parts lists being nonexistant, or inaccurate.  There is also the issue what items are important enough to be on the assembly tree.

Well, the only answer I've found so far, is that there are no standards for family drawing trees.  Other than a couple generic examples, nothing else seems to exist.

Thanks everyone.

RE: Drawing Tree Standards

From Ctophers link:

4.4. Drawing Tree
A drawing tree is used to control the development of drawings and their place in
the overall scheme of the project. Although this type drawing is not a
requirement for each project, when used properly and kept up to date, it can be a
valuable management aid and can be contained in a configuration management
database. See Figure 19.

However, that is a NASA doc not ASME so I can see why bashcraft is hesitant to take it as gospel.

If you have the Genium or similar manual they might have examples too, still not an ASME spec though.

RE: Drawing Tree Standards

(OP)
I did.  I guess what I'm looking for concerns the basic structure of the tree.  For example, a manufacturing engineer here wants to see the tooling/fixture drawings being referenced by the assembly drawings where they're used, while the production department wants the tooling all listed together on a separate sheet.  I suppose the easiest solution would be to do it both ways, but I was hoping to find some kind of standard for this.

thanks.

RE: Drawing Tree Standards

That's a pretty specific issue, most 'industry' standards don't delve into that level of detail from what I've seen.  Even for the drawing types 14.24 covers it doesn't got into that kind of level of detail.

RE: Drawing Tree Standards

I agree w/KENAT.

You can use the NASA info as a basis and modify it to suit your needs.

RE: Drawing Tree Standards

The example given is little more than an indented BOM.  It should not be a problem to include tooling in the tree, just adding them as subassemblies of the resulting part.

RE: Drawing Tree Standards

You can also add tooling to your production BOM in an ERP system, just use QTY 0.
