How can we create Hierarchies of models in ignition?

I am very new to Ignition so this may be a very simple question but i am stuck since last many days. I want to create hierarchies of UDT'S but im unable to do it ? Any idea how's that done exactly ?

Basically i want to create asset model hierarchy on sitewise using cyrrus link's iot bridge. The model hierarchy i want is as below

Model1 (UDT) has two models in it W1(UDT) and W2(UDT) . W1 has two assets in it WT1 and WT2 (UDT Instances) and these assets have multiple measurements (TAGS eg. Temperature etc)

Now i am not sure how i can create this hierarchy, so any kind of help would be highly appreciated.
Thank you

Create all your UDTs.

Then you can add UDT instances in a UDT, just like you would add tags:

Here I created UDTs Foo and Bar, then nested an instance of Foo named foo in Bar

Perhaps the misunderstanding is that you can't edit the structure of a udt instance; you can only edit them in the UDT definition itself. That is to say, you can't add or remove tags, including udt instances, into/from a udt instance

Thanks it helped

yeahhh right. Thanks for responding
