Examples for PyScript

PyScript is simple Zero Touch Node to run python scripts in a dynamo player (http://dynamobim.org).

• The Script.Execute node finds a python file with the same name as the dynamo file and launches it.
• Prints and errors are available for viewing from the dynamo player.
• The current folder is added to the search paths.
• To create a new script, you do not need to open dynamo: just copy any pair of <script name>.dyn / <script name>.py

Installation

1. Find and install PyScript package.
2. Connect Script.Execute to Watch node.
3. Rename and set as output Watch node.
