Multiple Materials Assigned to Bodies 1

[jmarkus]

If I delete a body in my model and I have other bodies present with materials defined I get the message:

"Multiple Materials are assigned to bodies, Please select the one to represent the part material."

Why do I get this message and can I control whether or not it shows up?

Thanks,
Jeff

Seems like you have one part with multiple bodies.
Why don't you use assemblies?

NX 7.5.5.4 with Teamcenter 8 on win7 64
Intel Xeon @3.2GHz

Nvidia Quadro 2000

The other bodies are used as construction geometry. At some point they may have been assigned materials in order to make some estimates about various properties.

The reason for the message is that an attribute is assigned to the Part file for the material assigned. Since NX allows multiple bodies, but also assumes that each part file represents a single detailed part (at least that is what is generally expected), this question is being asked simply so that the Attribute assigned to the PART file represents that Material that one would expect the part that the file represents is to be made from. It's just to help with the 'bookkeeping' as it were.

Thanks John, that answers the why. Is there any way I can prevent it from happening? Ultimately I'm trying to write a journal and because this happens sometimes, but not all the time (dependent on the part I am working with) it "confuses" my journal.

There's no way to stop you from doing this since there may be legitimate reasons for multiple material assignments which is why we ask you the question so that you can at least specify which is the 'official' material in terms of what the system should report when asked such as in a material column of a Parts List.
