Introduction

In this episode, we learn the first step of almost all Dynamo grabs, selecting elements from the Revit model. From walls, doors, windows, all the way to levels, everything can be selected in an instant. Let's get started. Hello! In this third episode, we learn how to select Revit elements with Dynamo. This is the first step for all automation that comes next.

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

Step 3: Select category - Categories and All Elements of Category

Select the category. Right-click on the canvas, search for the Categories node, then select wals from the list. Next, find the All Elements of Category node and connect the cable from Categories. This node takes all the walls in the project. Also connect to Watch, and you'll see the list of selected walls.

Step 4: Count the number of elements with List.Count

Add the List.count node and connect the wall list input. Then display the result with Watch. This house has 31 walls.

Step 5: Replace category - Doors then Windows

Now change the category. Select Doors, and the number count directly changes to the number of doors. Select Windows, and you'll see the number of windows. Just change one selection, and the entire grab adjusts accordingly.

Step 6: View the element names with Element.Name

We can also see the element name. Select the Levels category, then add the Elements.name node and connect the element list to it. The watch displays the project level names, which are floor 1 and floor 2.

Done! You can now select any Revit element

Done! You can now select any Revit element. In the next episode, we'll read element parameters. Goodbye! Want to master Dynamo and Revit?
