A recent post on the r/BIM subreddit sparked an interesting discussion: should you learn Dynamo or the Revit API for automating tasks in Revit? As a BIM professional, you’re likely no stranger to the quest for efficiency and automation in your workflows. But with multiple tools at your disposal, it can be daunting to decide which one to invest your time in. In this post, we’ll break down the key differences, benefits, and considerations to help you make an informed decision.
Understanding Your Options
When it comes to automating tasks in Revit, two popular tools come to mind: Dynamo and the Revit API. But what are the key differences between them, and which one is right for you?
- Dynamo: Ideal for those seeking a visual, user-friendly interface to automate tasks without deep programming knowledge. It’s particularly useful for quick prototyping and repetitive tasks. With Dynamo, you can create custom workflows and automate tasks without writing a single line of code.
- Revit API: Offers deeper control and flexibility but requires proficiency in programming languages like C#. It’s suited for developing robust, scalable solutions and integrating with other systems. If you’re looking to create complex custom tools or integrate Revit with other software, the Revit API is the way to go.
The Middle Ground – Python & PyRevit
But what if you’re looking for a balance between ease of use and control? That’s where Python and pyRevit come in.
- Python: Learning Python can be beneficial as it’s versatile and widely used in various applications beyond Revit. Python is a popular language that can be used for automating tasks, data analysis, and more.
- pyRevit: Combines Python scripting with Revit, offering a balance between ease of use and control. However, be aware that pyRevit currently relies on IronPython 2, which has known security vulnerabilities. This reliance may pose risks, especially in environments where security is a priority.
Security Considerations
When it comes to pyRevit, security is a concern due to the use of IronPython 2, which has unpatched security vulnerabilities. Notably, Jacob Small from Autodesk raised this concern in the thread, emphasising the need for caution when using pyRevit, especially in production environments. Given his expertise, it’s wise to heed this warning: if security is a top priority for your organization, you may want to exercise caution when using pyRevit.
Practical Advice for Your BIM Automation Journey
So, where do you start? Here are some practical tips to help you on your BIM automation journey:
- Start with Dynamo. For beginners, Dynamo provides an accessible entry point into automation within Revit. With its visual interface and user-friendly workflow, Dynamo is perfect for those new to automation.
- Advance to Revit API. As you become more comfortable and if your projects demand more complex solutions, transitioning to the Revit API can be advantageous. The Revit API offers deeper control and flexibility, making it ideal for complex custom tools and integrations.
- Stay Informed. Keep abreast of updates to tools like pyRevit, especially concerning security enhancements and support for newer Python versions. Staying informed will help you make the most of your automation tools and ensure you’re using the best solutions for your needs.
Choose Your Path
In conclusion, the choice between Dynamo, Revit API, and pyRevit depends on your goals, comfort level with programming, and project requirements. By understanding the strengths and weaknesses of each tool, you can make an informed decision and start automating your Revit workflows with confidence.
