Randomized trees by area in Revit

Today I'm going to show you a workflow for generating a number of randomly placed trees inside an area in Revit.

Once again I utilize the topo to surface conversions which I've shown you before.

The workflow:

1. Draw a closed area with model lines. (Must be higher than the topo)

2. Select the model lines in Dynamo

3. Select the topo in Dynamo

4. Set the number slider according to your taste for tree quantities..

5. Run!

The definition looks like this:
