While we are still in V6R2013x, we have seen the same
thing.
We have chosen, for the most part, to ignore the CATIA
Materials, and instead focus on the ENOVIA Materials. I'm not
sure if DS has unified these objects yet, but at R2013x they have
not.
We have found that, in the CATIA World, Material has a different
meaning that it does in the ENOVIA/EBOM world. In CATIA, it
is primarily physical properties such as Mass and the Analysis
Domain properties. It can also represent the manufacturing domain
properties such as feeds and speeds, etc.
In the ENOVIA/EBOM World, it actually represents the purchased
raw material. This is an entirely different thing. For
example, in the CATIA World, there are only 3 or 4 Aluminum
materials that you need to worry about due to the Mass, FEA, and
Manufacturing Properties. If you are using Sheetmetal, then you
also need to understand Thickness and Temper. In the
EBOM, Raw Materials also include purchasing information such as
Flat stock vs. Rolled Stock, Arbor size on the rolled stock.
Heat Treat. Quality Spec. cladding, etc. So, in
the CATIA world, there are a few hundred Aluminum materials.
In the EBOM world, there are thousands of materials (and the MBOM
world multiplies this even higher, by adding information such as
Vendor and purchase amount).
