Using Dynamo with Python

Developers

Hello everyone, My name is Emmanuel Katto. Can someone explain how to effectively use Python scripts within Dynamo? I’m looking to perform more complex calculations and data manipulations than what is feasible with standard nodes.

Looking forward to your help.

Thanks in advance!

Best,
Emmanuel Katto

Im usually using python script for all my Dynamo tool. The main reason I do that because

  1. Enhanced Control: Python scripting allows for better control of the workflow by organizing logic through well-defined methods and functions.
  2. Code Efficiency: It enables you to write more concise and maintainable code…
  3. Revit API Access: You can leverage the full power of the Revit API, allowing deeper customization and interaction with Revit documents.
  4. Node Independence: Python scripts remove the dependency on nodes in Dynamo, offering more flexibility and fewer limitations.
  5. and so on.

@hoangthanh7897 pretty much summed it up with a special emphasis on item #2 Code Efficiency. Packages are written for general public use. You can customize your code for your specific needs. Example: If you need to get a specific element in the model. With nodes, you have to designate the category. Get all elements by that category and then filter that list either by the element name or by a parameter value. This could take anywhere from 5 to 10 nodes to accomplish. All of that could be put into one python script.

Now with that being said, there is a caveat to @hoangthanh7897 item #4 Node Independence. OOTB nodes are and third party packages primarily are maintained by someone else and updated as/when the Revit API changes from version to version. By using your own code, that responsibility falls onto you to make sure your code works for the next version of Revit.
