How to Select Project Components Using Dynamo

How to Select Components in a Project Using Dynamo

When working with Dynamo and Revit together, it’s often necessary to first select and link relevant components within Revit. So, how can we efficiently use Dynamo to quickly select the components needed in a project?

Depending on whether you know the component type, category, or family name, here are some effective methods:

If you know the component type or category:

Method 1:

• Categories: Access all built-in categories.
• All Elements of Category: Retrieve all elements from the model that belong to a specified category.

Method 2:

• Code Block: Write Design Script code directly.
• Class.ByName: Obtain Revit categories by their built-in category names.
• All Elements of Category: Retrieve all elements in the model for the selected category.

If you know the family name or component type:

Method 1:

• Code Block: Write Design Script code directly.
• FamilyType.ByName: Select a FamilyType by its name. If multiple FamilyTypes share the same name, this method returns the first one found.
• All Elements of Family Type: Retrieve all elements in the model of the specified family type.

Method 2:

• Family Types: Access all available family types in the document.
• All Elements of Family Type: Retrieve all elements in the model matching the selected family type.

If you want to select all components visible in the current view:

• All Elements In Active View: Retrieve all visible elements in the active view.

By applying these methods, you can quickly and easily select the components you need in your project.
