Introduction

In this episode, Dynamo writes the krefit data, column comments for 31 walls are filled at once, without clicking one by one. Let's get started. Hello. In this fifth episode, we write element parameters with Dynamo. Use a project copy, because Dynamo directly modifies the model.

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. At the start page, click New to create an empty workspace.

Step 3: Select all project walls

Select all walls with category S, then choose Wals, and then All Elements of Category.

Step 4: Prepare the parameter name and its value with Code Block

Create two code blobs. The first one contains the parameter name, which is comments in quotes. The second one contains the text to be written, which is the DL004 house wall.

Step 5: Write to Revit with Element.SetParameterByName

Add the element.set parameter node by name. Connect the wall list to the element, comments to the parameter name, and text to the value. Since Dynamo runs automatically, all walls are automatically populated.

Step 6: Check the result in Revit - Comments column in Properties

Let's check in Revit. Shrink Dynamo, click on one of the walls, then scroll the properties panel to Identity Data. The comment column is already filled by Dynamo.

Done! 31 walls filled at once

Done. One node writes 31 walls at once. In the next episode, we'll learn about lists in more depth. Goodbye. Want to master Dynamo and Revit?
