Dynamo Python — Dictionaries from Python to Graph
Why a Python dict cannot be consumed by Dynamo nodes downstream, and how to use System.Collections.Generic.Dictionary from Python to produce a native Dynamo Dictionary output.
Dynamo Python — Distribute Lines Along Curve
A Dynamo Python script that places perpendicular lines at parameter positions along a polycurve, interpolating their lengths across multiple input target lengths.
Dynamo Python Tips
Essential IronPython tips for Dynamo: creating Revit geometry with Autodesk.Revit.DB, modifying the model via TransactionManager, and retrieving elements by ElementId.
Geometry Conversions in Dynamo with Python
Using RevitNodes.dll geometry conversion extension methods in IronPython to convert between DesignScript types and Revit DB types — Point, Vector, Solid, Curve, and Transform.
Element Design Option
A Dynamo Python script to retrieve the Design Option name for a set of Revit elements, enabling filtering by design option in your graphs.
Parametric equation of circle and ellipse
Applying the parametric equations of a circle and ellipse in Dynamo to generate computational geometry, including spirals, 3D forms, and heart shapes.
Sagitta
A computational design approach to the sagitta — the perpendicular height from a chord's midpoint to an arc — implemented as a reusable Dynamo custom node.
SepparateCurvesByDistance
A Dynamo Python node that groups imported curves from Revit into connected sets based on proximity, using a configurable maximum distance threshold.
Getting rooms with python in Dynamo
How to get all rooms in Revit using Python inside Dynamo, filtering by SpatialElement with the FilteredElementCollector.
