Hi All,

I am developing a Custom UI Node which I want to put few selection model element button together. Currently I am able to select elements from Revit (tested by using Zero Touch), but I am stuck at how to convert these elements to AssociativeNode so can be output by dynamo custom UI. Is Dynamo even allow developers to do custom selection in such way ?

**Script to Select elements from Revit:**

**Zero Touch Test**

**Custom UI Test Connection**  
For this code , i just want to make sure the elements is being selected and stored in the system.

Hi @Clover  
There are a couple resources for this. There are instruction for "Custom UI " nodes:

> **[DynamoDS/Dynamo](https://github.com/DynamoDS/Dynamo/wiki/How-To-Create-Your-Own-Nodes)**
>
> Open Source Graphical Programming for Design. Contribute to DynamoDS/Dynamo development by creating an account on GitHub.

And a more in depth discussion of these more advanced nodes here:  
[https://github.com/teocomi/dug-dynamo-unchained/tree/master/dynamo-unchained-2-learn-how-to-develop-explicit-nodes-in-c%23](https://github.com/teocomi/dug-dynamo-unchained/tree/master/dynamo-unchained-2-learn-how-to-develop-explicit-nodes-in-c%23)

And you can look at the specific code used to create selection in Revit in Select Model Element here:

> **[DynamoDS/DynamoRevit](https://github.com/DynamoDS/DynamoRevit/tree/Revit2018/src/Libraries/RevitNodesUI)**
>
> Dynamo Libraries for Revit. Contribute to DynamoDS/DynamoRevit development by creating an account on GitHub.

Hope that helps!

DynamoSamples repo may be the simplest to use.

I am able to get the Curve from Revit now but it brings out other issues.
