Why not use parts with datum curves rather than skeletons?

[daveykbelgium]

i have a lot of experience with top-down assemblies using skeletons, layouts etc.

however, using skeletons does not give the ability to use skeleton dimensions in parts because even using a skeleton directly in a part, i.e. even ignoring publish and copy geometry, you can't get the skeleton dimensions to appear in the part

if i use parts just containing datum curves as pseudo skeletons, i can put these in an assembly with the part, and model the part using 'create feature in assembly mode'.

i'm pro/e to the core, but what benefits other than filtering skeletons out of parts lists are there?

okay, i exclude the answer of using one 'master skeleton' to pass information to individual skeleton parts of my pseudo skeletons, keeping the bounding box of my part small, and only referencing the minimum amount of information - don't forget, using such functionality will drop the ability to use the dimensions!

i still think the price to pay is worth it, as the same dimension scheme can be easily recreated in the part drawing.

I've used datum curves as a pseudo skeleton part because my company didn't have the Advanced Assembly Extension (AAX). It worked really well.

Do you trust your intuition or go with the flow?

Ah, this is a historical problem. I have been using two solutions:
Inheritance features (limited to not having any optimization features in them, boo!) gives you access to the features in the source part.
Using relations the get back the dimensional values.

A third alternative that may work (I have not been able to use it robustly) is utilizing annotation features. These are basically the equivalent of "created" dimensions in the part (or assembly) mode.
