@JamesMannFusion thanks for the feedback.
The problem with these tubes is that they are NOT configured components. They re "embedded" in the assembly design. The assembly has configurations that modify parameter values.
These tube designs use those parameters, so when I change the configurations, the parameters change and so do the tube designs.
I think what that leads to is that I have to create those tubes as external designs with their configurations, and use them as XREFs just as many of the other components. I've been trying to avoid that!
The parameters that drive the tube dimensions are part of that assembly design. Updating those dimensions, changes the tube designs, but also changes a number of other things in the assembly design. The update is limited to the assembly design and happens very quickly. However, to drive the fully modular and parametric nature of this design I also need to rely on an external master parameter list that that drives other things in the design and changes many of the individual external components in that design.
Now It seem that I have to move the parameters from the assembly design into that master parameter list. Unfortunately, due to lack of granularity control, any change to any parameter in the master parameter list will require an update to any component that uses any parameter in that list, even if the actual change doesn't even effect that component.
What a mess!
Also, "save as" obviously breaks the parametric nature of the design, so that isn't a solution, unless I delete the original and proceed as described above.
As can be seen in the screenshot I provided, one of the configured external designs is missing. The thing to note here is that this XREF is only missing on my Windows desktop at home. It is NOT missing when I open the design on my work notebook, or on my MacBook pro. This is another reason I am trying to avoid complex changes to this configured design. This happened while updating the design after changing one of the parameters in the Master Parameter List, hence my reluctance to put more parameters into that list!

I have the strong feeling to get my work done I will have to resort to yet another hack 😞
