Copy Paste Room Number Value to Another Column in Same Room Schedule

Revit
1

I am trying to copy all the room numbers from one column to another in the same schedule and then replace a letter in the room number with a hyphen. I’m new to Dynamo and was wondering if anyone could help.

  1. Categories node > All Elements of Category node to get all rooms.
  2. Element.GetParameterValueByName node to get the parameter value which you want to swap a letter for.
  3. String.Replace to change the letter into a hyphen.
  4. Element.SetParameterValueByName node to set the new parameter value from the modified string. Note that your element input comes from step 1, and the value comes from step 3.
  5. Verify the results in your schedule.

If you get stuck, post an image of your attempt with all data previews expanded, which is created via the export canvas as image tool after you zoom in so the node names, inputs, and data previews are all legible (Camera icon or Export button in the top right, or Export in the file menu).
