How to Use Geometry in Dynamo for Revit — Cuboids, Surfaces & More

Geometry is the foundation of advanced Dynamo automation. This complete beginner's guide shows you how to create geometry inside Dynamo, import it into Revit, extract geometry from Revit elements, and analyse surfaces — including finding the face with the largest surface area automatically. ✅ What You'll Learn: ✅ The two types of geometry in Dynamo — created inside Dynamo & extracted from Revit ✅ How to create a cuboid using Cuboid.ByLength and set its origin point ✅ How to retrieve the width, length, and height back from any cuboid ✅ How to import a single geometry into Revit using ImportInstance.ByGeometry ✅ How to import multiple geometries at once using ImportInstance.ByGeometries + L1 lacing ✅ How to draw a wall in Revit and select it with Select Model Element ✅ The difference between Element.Geometry (all geometry) and Element.Solid (solid only) ✅ How to get the top surface of any geometry using Geometry.TopSurface ✅ How to explode geometry into all its surfaces with Geometry.Explode ✅ How to calculate surface areas and find the largest surface using List.MaximumItem ✅ How to get the volume and area of any solid in Dynamo ━━━━━━━━━━━━━━━━━━━━━━━━━━ ⏱️ TIMESTAMPS / CHAPTERS 00:00:00 - Introduction: Geometry in Dynamo 00:00:11 - Two Types of Geometry in Dynamo 00:00:35 - Cuboid.ByLength Node: Creating a Cuboid 00:01:18 - Setting Width, Length & Height 00:01:43 - Zooming to Geometry with Control+B 00:02:03 - Changing the Origin Point with Point.ByCoordinates 00:02:35 - Cuboid.ByCorners Node 00:02:47 - Getting Width, Length & Height Back from a Cuboid 00:03:26 - Importing Dynamo Geometry into Revit: ImportInstance.ByGeometry 00:04:53 - Importing a Single Geometry 00:05:14 - ImportInstance.ByGeometries: Importing Multiple at Once 00:05:47 - Using L1 Level to Separate Imported Geometries 00:06:39 - Drawing a Wall in Revit & Selecting with Select Model Element 00:07:28 - Element.Geometry vs Element.Solid: Key Difference 00:08:36 - Extracting Wall Geometry with Element.Geometry 00:09:08 - Geometry.TopSurface: Getting the Top Surface 00:09:37 - Geometry.Explode: Breaking Geometry into All Surfaces 00:10:16 - Surface.Area: Getting the Area of Each Surface 00:10:50 - List.MaximumItem Index: Finding the Largest Surface 00:11:32 - List.GetItemAtIndex + L2 Lacing to Extract That Surface 00:12:10 - Getting Volume & Area of a Solid 00:12:41 - Recap & Closing ━━━━━━━━━━━━━━━━━━━━━━━━━━ 🚀 Want to go further?
