[Dynamo] Trying to place wall finishing on RC wall, column etc

[Ben39000]

Hello everyone,

I’m hoping to get some assistance with a Dynamo script. I’m trying to place a family type into my Revit model at specific coordinates that I’ve pulled from an Excel file.

I’m using Dynamo 3.03 and Revit 2025.

The script is running, but the last nodes are returning a null value and not placing any elements. I’ve no idea how to overcome this.

Here is a screenshot of my current graph: [Insert link to a screenshot here]

I’ve also uploaded my Dynamo script and a sample Excel file here if anyone wants to take a look: https://drive.google.com/file/d/1OcD4UjVfXRM5Reqm41VvcjhF-4q6toRP/view?usp=sharing

Any advice or guidance on what I’m doing wrong would be greatly appreciated. You can access the .dyn file from the link below:

Create Finish Walls Around Structural Verticals..dyn

Thank you so much in advance for your time!

Screenshot and Excel file are missing?

What are you selecting in your Dynamo here ?

Also in your script there is nothing which points to an Excel? So i don’t understand this .

EDIT

After bit of fiddling with your .dyn. i get (to) this.

"Int32" error using RVT24

Hi all, I’ve been using the graph below succesfully for Revit 23-models, but it stopped working in Revit 24. The Element.IntersectsElement-node returns the error ‘Int32’ method not found. I have no idea what this means. I was a great fan of this node and wouldn’t want to eliminate it in favor of the variant using bounding boxes. Anyone knows what is going on and how to resolve it?

This one works though . So my guess the issue is in the node(s) from the WombatDynamo package.
