Something that has been confusing to students in my Weldments training classes is the proper way to create Sub-Weldments so that they retain all the work you have done creating properties for the cut-list items.
As of SolidWorks 2012 this is definitely possible but you have to do it in a specific way. The thing to remember with this is that the actual bodies do not store any properties, only the Cut-List Item folders do. So of course you have to do an “update” to your cut-list at least once before proceeding
Here are the steps for successfully creating a Sub-Weldment:
1. Create your weldment as normal.
2. Update the cut-list and add any additional properties to the folders.
3. Ctrl+Select the BODIES you want to make into a sub-weldment (either from tree or from screen with bodies filter).
4. Right+Click, CREATE SUB-WELDMENT.
This will even take the properties with the sub-weldment if you save it out to a separate part file (using right+click, "Insert into New Part" on the sub-weldment). They will also be tied/related back to the original weldment file for updating!
Of course, as an alternative to actual “sub-weldments” done this way you can always just make a weldment, make another weldment, and then stick them into an assembly together. The above method is nice because it keeps it all in one multi-body weldment part file rather than having to manage an assembly with multiple parts.
