Can NX populate overall part dimensions into the attribute table? 1

Hey guys, brand new to the group, not to NX. Thanks in advance for your help, I hope to contribute as well.

I'm learning a lot about how to modify a pax file to have it populate the BoM for the information we want. It's the typical info: number, quantity, material and size. Normally we create the finished size but the higher ups would like us to add the stocked-in size to the BoM as well. I have to edit the pax file to pull the "stock size" attribute. Our current method is typing in the finish size dimensions into the attribute table manually. When an assembly has 200 individual components, that's a LOT of time spent typing by hand. Of course, it opens up the opportunity for typos. Now, we will be doubling that amount of manual typing as we determine the stock material as well.

It just seems to me that there must be a way for NX to populate the dimensions to the attribute table. Can this be done? If so, would PMI work best? What about a drawing with just three dimensions for the X/Y/Z overalls that can then automatically be populated into the attributes table without manual keying - even if expressions were necessary.

Does anyone have a method that can do this? I did a lot of reading on this page before posting and some guys mentioned PDW has something that would help with the BoM and mass-editing the attributes but we don't have that module. It doesn't matter to me if this works at the component (part) level or the assembly level but we currently add it to the attributes at the part level because we need to see the PMI dimensions when keying.

To add another level, we determine our stock sizes based where we will get the material. For example, if we order steel from a vendor who can pre-square it we may only stock .010-.020/side. If we are ordering rough-sawn, that stock jumps to +.250. Now...IF it is possible to get the X/Y/Z overall finish dimensions to populate into the attribute table, is it then possible to create an expression for it to automatically calculate and populate the stocked-in size?

Thank you, WB!

I assume that you are discussing parts lists and not pax files.
The pax files can arrange a number of available parts lists and /or file templates but not the parameters.

Partslists reads attributes , not expressions .
You can create new attributes which reads an expression, i.e "pipe an expression into an attribute" which makes it available for the partslist.

If you are running NX w Teamcenter, the body extents are available in Teamcenter. ( Named references on the Model , - "UGPART-BBOX")
this however might not be the desired format.

In your case, you could create a model template in which you have a "bounding body" feature defined , its variables ( expressions) linked into attributes.
when finishing of a project, drag the bounding body to become the last feature, edit and include the workpiece.
then the partslist can report the size without further work.
