Applying Material and DENSITY within Family of Parts?
Applying Material and DENSITY within Family of Parts?
(OP)
In NX6, (also in 7.5) I'm creating a Family of Parts. I can apply a material to the master part and then I create the family of parts to include the attribute, "material." The density attribute field from the variable pull-down list (while setting the columns for excel) doesn't give me any choices to select so it looks like no density is set, only "material." In Excel, I fill in all of the required columns with my dimension data and also type in different materials. The Part Family is saved and works fine, except, even when the material attribute looks fine, the density never changes from the material set on the master part. It doesn't look like the material pushes back into the newly created components. So, How do I get the density to be set correctly for my components created with the Family of Parts tool? I hope I don't have to create a different family for each material. -thanks.





RE: Applying Material and DENSITY within Family of Parts?
Note that tying the Density to a 'NAMED' body allows you to have Part Family models with more than one body, each of which could be a different material and you would still be able to assign densities to any or all of them.

RE: Applying Material and DENSITY within Family of Parts?
I created the spreadsheet as per your instruction and assigned Aluminum-2014 with 2794 kg/cu m, but in spread sheet it is showing 0.30379 value (I am using NX5). Even if I assign different material it shows the same value 0.30379. Need help. Thanks in advance.

Using Tools - material Properties - then selected the solid body and assign the material by choosing the Library material.

Could you create a simple example where you see this behavior and attach it to a reply?

Here is the family part file contains the field NAME1 under density. I, just now realize that only this file is misbehaving. I tried to create a new family part file using your options, are working fine. Please check what is wrong with this file.
Thanks

This file I used from the CAST parts directory of NX5. I have not run any FEA. Thanks again.

Thank you for the valuable information which affect the material property expressions.

RE: Applying Material and DENSITY within Family of Parts?
Today I opened your attached file and change the material to Steel, it is not updating inside Part family but it updates inside part attribute dialog.
I deleted the existing part family and recreated using the same thing, then it updates for the changes. Any reason?
Could you please let me know how you created the Part Attribute with MATERIAL which updates itself inside the part attribute dialog once I assign different material. Thanks

Now I have the correct picture of the family of parts.
How about my second question
"Could you please let me know how you created the Part Attribute with MATERIAL which updates itself inside the part attribute dialog once I assign different material."
How to link the MATERIAL value to the assigned material, as per your part.?
Thanks

Tools -> Materials -> Assign Materials...
This is will not along set the proper Specific Density for your model but will also properly tag the model's material ID for downstream applications such as FEM/FEA and assign both Part and Object Attributes with the name of the assigned material
