Introduction

In this episode, we use Python in Dynamo to read the names of all walls. Let's start. Hello! In episode 16, we use a Python script in Dynamo.

Step 1: Open Dynamo from the Manage tab in Revit

Open Dynamo from the Manage tab in Revit, then click Launch Dynamo. Wait until the window opens.

Step 2: Create a new workspace with the New button

On the initial page, click New to create an empty workspace.

Step 3: Select the wall and prepare the Python Script node

Select all walls using Categories and All Elements of Category. Then right-click on the canvas, find the Python script node, and press Enter. This node has an input in 0 and an output out. Connect the wall list into its input.

Step 4: Open the editor - right-click then Edit

Right-click the Python script node and select Edit. The editor opens. Delete the default code, then type one line: out equals a list containing the name of each element in in 0. Data entering from in is read, and the result is sent through out. Click Save and Run, then close the editor.

Step 5: Save and run then view the result in Watch

Add a watch and connect the Python output. You can see the list of names of all wall types.

Done! Python reads the name of all walls

Done. You can now use Python in Dynamo. In the next episode, we will import data from a CSV file. Goodbye. Want to master Dynamo and Revit?
