Episode Description
In this episode, Michael Kilkelly interviews structural engineer Bob Barnett about his programming journey from early computing with punch cards and FORTRAN to creating sophisticated Revit add-ins that automate structural calculations. Bob shares how he uses code to eliminate errors in his work, his experiences learning the Revit API, and his approach to building custom tools that make his structural engineering practice more accurate and efficient.

Key Takeaways

Bob focuses on automating calculations to eliminate transcription errors rather than just saving time.
Working on one structural element at a time gives engineers better control and understanding than running large models.
The Revit API provides access to all model data, allowing for direct calculation without manual data entry.
Learning programming fundamentals enables building powerful custom tools specific to your workflow.
AI tools can significantly accelerate the coding process, but you still need to understand programming basics.
