Revit BuiltInCategory Enumeration (2018.3)
I searched and searched for hours and still have not found a list of all members of the BuiltInCategory enum along with their hashcodes. This is very helpful for working with shared parameters which need the DATACATEGORY value, as you cannot use the name of the built-in category (Revit looks for the hashcode in the…

Dynamo’s Security Vulnerability
Last week, I decided to see how far I could push Python nodes in Dynamo in terms of files external of Revit and I believe I have discovered a vulnerability in which an attacker can use a Python node within a Dynamo graph to gain access to your desktop. There have been some similar discussions…

Use Dynamo to Transfer Phase Data to Bound Revit Models
This workflow was created as a request from @PhilosophyBIM on Twitter To @DynamoBIM guru, any way to automate the phase mapping to revit elements? I have a linked model binded to another file & lost all Phases. — Philip Chan (@PhilosophyBIM) September 26, 2017 The issue arises when binding a linked model in Revit. If…

Dynamo Graph to push Space data into COBie.Component.Space including elements above the ceiling (MEP)
Here is a graph that I’ve thrown together that pushes the Revit Space number into the COBie parameter “COBie.Component.Space” for elements that are within the Space, including elements above the ceiling. Note that in order for this to include the elements in the area above ceilings (i.e., mechanical and electrical equipment), your spaces must use…

BIMxDB v0.0.2 Published – Store Revit Data in SQLite Database
To supplement the BIMxHTML Dynamo package, I published a second package called BIMxDB. This package will contain several custom nodes for exporting Revit data to different types of databases. For now, my focus is SQLite and the current node that is in the package is Export.SQLite.ParameterData.TimeStamped. This custom node creates a table in the SQLite…

BIMxHTML v0.0.8 – More Custom Nodes to Generate Google Charts
It looks like there has been some interest in the BIMxHTML Dynamo package and its encouraged me to develop some custom nodes to simplify the display of Google Charts using pure Dynamo. The Custom Nodes Download the sample files below to get a good example of how to use these nodes. Essentially, they output an…

BIMxHTML – A Dynamo Package to Generate Web Pages
All of the excitement revolving around generating dashboards using Power BI made me wonder: Can we leverage Dynamo to create web pages that display data directly from a Revit model? The goal would be to create a powerful, free alternative to generating web-based content using simple HTML code. Needless to say, the gears have been…

A new approach to developing and implementing standards.
This post was originally posted to OpenRFA.org on June 1st, 2017 and is shared here for posterity. At OpenRFA, we’re not only pushing for standardization, we are proposing a new approach to developing standards through open collaboration. So far, I have yet to see an industry standard (BIM or other) that has been developed through collaboration…

The Value of Standardized Shared Parameters
This post was originally posted to OpenRFA.org on May 8th, 2017 and is shared here for posterity. In Revit, shared parameters are unique – each shared parameter has its own Globally Unique Identifier (GUID) assigned at time of creation. This means that just like a person, parameters can have the same name but never the…

Hello Dynamo World!
In learning every new programming language, it is customary to start with a “Hello world!” application. Although visual, Dynamo is a scripting tool as well, so I thought this would be a great first step for folks who are new to Dynamo. In this post, we demonstrate how to display “Hello world!” in the Revit…
