One of the most useful built-in automations in Revit is the “Tag All Not Tagged” command. However it tags elements in the active view only. In larger projects we often have dozens of views where we have to repeat the procedure. Therefore I have tried to create a Dynamo/Python script that can work on a […]
Auto-dimensioning rooms with Dynamo and Python
In this post (series I hope) I want to share some thoughts on possibilities of adding dimensions to rooms in Revit automatically. It is not a trivial task in my opinion, especially that there is no single good solution! Today I want to present a script that, in most cases, is going to dimension rooms […]
Extracting data from OSM file with Dynamo and Python
While there are some great packages available, like Elk or DynaMaps, to do the task – sometimes we need some data that is not possible to obtain with them. In this post I am gonna show a method to extract necessary data using Python. For parsing a XML file I am gonna use a standard […]
Creating elevation views with API
Creating section views at given location and direction with Revit API is relatively easy. You just have to create a right Bounding Box (it’s dimensions and transformation) and pass it as a constructor function parameter. Unfortunately it is not so easy with elevation views. The elevation views in Revit are not independent – they have […]
Efficient auto-join using Dynamo
[Similar problem in C# has been presented in another post] Joining model elements in Revit can be a tedious task. Surely it is something that most of us would like to automate with Dynamo. Hopefully we can easily find some custom nodes that can join elements. We can also do it with Python using a […]
Finding element location by using Bounding Box in Dynamo
Most of the times Revit element location can be easily found in Dynamo with a help of some standard nodes – such as FamilyInstance.Location. There are some element categories however, that can cause a bit of a problem. For instance walls will return their location as a curve rather than a point. Elements that are […]
Room boundaries from linked documents
Generating room boundaries with Python is relatively easy. It can be done by using following API call: Options is a variable of SpatialElementBoundaryOptions type, which states desired boundary line location, eg. for walls it can be a finish line or centreline. As a result of the above we receive a list of loops, where each […]
Resetting MEP systems overrides
Revit MEP models allow overriding graphical display of entire MEP systems. It can be problematic when linking such models to eg. architecture. Often we would like to adjust visibility settings of MEP elements, but it cannot be done because of those overrides. Their priority is higher then view templates or filters. A solution for that […]
Dimensioning elements from linked files with Dynamo
In one of the previous posts I have shown how to dimension curtain walls with Dynamo and Python. A thread on the Dynamo Forum made me realize that it will not work in case of elements coming from linked documents. In order to create a new dimension line by script in Revit we have to […]
