Why Insertion Sort Of Property Sorting in Dynamo involves many unnecessary visual nodes which complicates the script. Insertion sort of property is similar in output with Double Sort node but instead of pre-extracting the values to be sorted you just pass as a string the name of the proeperty Description Let’s say you have a setRead more
Description To get the design option of a set of elements (for filtering purposes) you first need to check if the design option is set or not and then access it. For most elements in Dynamo you first need to get the DB element and then access the required property. Solution

Description A computational design approach to sagiita. The sagitta is the height of an arc. It is the perpendicular from the midpoint of the arc’s chord to the arc itself. First step is to define the circle and the equation in a code block Second step is to project the point determined by sagitta heightRead more
Description This computational design algorithm is based on parametric equation of a circle: x = h + r cosθ y = k + r sinθ where h and k are the center point coordinates, r is the radius and θ is the angle between 0 and 360. In dynamo by defining the x and yRead more
Description A point can be defined in relation to it’s position towards a light. How to determine if it’s on the line, on the left or right side? This computational algorithm which is basically just applying a simple mathematical equation will determine on which side a particular point is in reference to a line. TheRead more
Why? In Dynamo you get to deal a lot with lists. In many situations the core nodes are enough and you can build most of the need functionality with them. However this in some cases turns out to be extremely tedios and it removes the focus in the script from it’s actual value to theRead more
Description If you want to rotate an element (but not passing a value to the rotate parameter) you can use the transform util provided by Revit. Just make sure that the passed line is an Autodesk.Revit.DB.Line Solution

Description Dynamo handles lacing on it’s own(provided that the python script is within a custom node), however sometimes you may have to handle multi-dimensional arrays by your self. The solution is simple, you use recursivity. Basically you iterate through each element in the list and if the item is a list, then apply the iterateRead more
Description To handle lists in Dynamo you may want to choose the python editor. It’s a very strong tool but taking the non-typed nature of python it’s not that easy determining what kind of input data you have. Even if IronPython is integrated in the .NET framework you cannot just test for IEnumerable interfaces asRead more
To write a library for dynamo in c# you need to add a reference to several libraries. The easiest way would be to use Visual Studio Package Manager, in there you type “Dynamo Visual Programming” and install the following: An important thing about writing your method in dynamo is provide functionality for multiple cases.
