Introduction

Welcome to the expert level. So far, Dynamo has been reading and modifying elements. In this episode, Dynamo creates a new wall from 4 points. Let's get started. Use a project copy, please. Hello. In this episode 14, we create a Revit wall from a line using Dynamo. Use a project copy.

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

Click New to create an empty workspace.

Step 3: Define four corner points with a Code Block

Define 4 corner points with CodeBlock, Pan.by Chordinates for each corner, forming a 4 m x 3 m rectangle next to the house. Collect them in a list named PTS.

Step 4: Connect the points to form four lines

Connect the points into lines with line.by StartPan and Pan. The starting point is PTS, the ending point is PTS shifted one position with list.shiftindexes, so that 4 lines are formed to close the shape.

Step 5: Select a level and wall type

We need a level and a wall type. Add the Levels node and select Floor 1, then the Wall Type S node and select the exterior wall 215BWK. Create a CodeBlock containing the height 3000.

Step 6: Create the wall with Wall,ByCurveAndHeight

Add the Wall.by Churvey and Hack node. Connect the lines to Churvey, height to Heik, Level, and wall type. In an instant, 4 walls are formed in Revit.

Step 7: Check in Revit - four new walls on the Floor 1 plan

Let's check in Revit. Open the first floor plan, and you'll see 4 new walls next to the house.

Done! The walls are automatically created from the lines

Done. Walls are automatically created from lines. In the next episode, we will place families. Goodbye. Want to master Dynamo and Revit?
