I have a series of repetitive structural-modeling tasks inside Revit that need to be converted into a Dynamo-based workflow. The goal is to press one button and have the script automatically create the required geometry, apply fully parametric controls, and run a quick self-check that flags or fixes obvious clashes or input mistakes before the model is saved. Scope • Build a Dynamo graph (or Python nodes inside Dynamo if necessary) that generates key structural elements—columns, beams, floors, and their joins—based on a small set of user inputs. • Expose parameters so engineers can later tweak sizes, offsets, and materials without touching the code. • Integrate an error-detection routine that warns about duplicate elements, misaligned levels, or values outside predefined ranges and, where possible, corrects them automatically. • Package the solution with a brief PDF or Markdown guide: installation steps, required Revit version, and a quick tutorial on extending the script. Acceptance criteria 1. Running the graph in an empty project populates all requested elements at the correct levels and coordinates. 2. Changing any exposed parameter instantly updates the created elements without manual refreshing. 3. Intentional bad input (e.g., out-of-range beam length) triggers a clear on-screen message and prevents corrupt geometry. 4. All nodes remain readable—grouped, named, and commented for future maintenance. If you have prior examples of Dynamo scripts that automate structural modeling, a short screen capture or screenshots will help me see your style.
