Hi, I can get some of the layers but have all sorts of different wall build ups. Is there a node to get all layer references instead of just cores and outer edges.
Try this, I think this is what you are looking for
Thanks RevitRobot. Both the reference outputs of compound Edges give me overall dims.
Wall Layer References give me below. I’m not sure how to remove duplicate references @Alban_de_Chasteigner if you possibly know? 
Also getting some center refences on cores for some reason.
This is just a suggestion and it would be more of a bandaid, but perhaps you can do something with counting the layers and adding a formula that checks whether it needs to grab the exterior reference.
In other words, it seems the node just grabs all the layers you ask for. But perhaps filter the layers references you actually want afterwards.
Hi,
1- You can use the “Vector.PruneDuplicate” node in the clockwork package to solve this, you can really get a good result with the correct tolerance values.
2- If you still see “0” values, you can find the references to the “0” values and filter again(This requires a node in the genuisloci package). This will give you a clean reconstructed dimensions.
Curiously. Is it not possible to access references outside of core or ends for dimensioning?
