Managing and Visualizing Your BIM Data

Overview of this book

Business intelligence software has rapidly spread its roots in the AEC industry during the last few years. This has happened due to the presence of rich digital data in BIM models whose datasets can be gathered, organized, and visualized through software such as Autodesk Dynamo BIM and Power BI. Managing and Visualizing Your BIM Data helps you understand and implement computer science fundamentals to better absorb the process of creating Dynamo scripts and visualizing the collected data on powerful dashboards. This book provides a hands-on approach and associated methodologies that will have you productive and up and running in no time. After understanding the theoretical aspects of computer science and related topics, you will focus on Autodesk Dynamo to develop scripts to manage data. Later, the book demonstrates four case studies from AEC experts across the world. In this section, you’ll learn how to get started with Autodesk Dynamo to gather data from a Revit model and create a simple C# plugin for Revit to stream data on Power BI directly. As you progress, you’ll explore how to create dynamic Power BI dashboards using Revit floor plans and make a Power BI dashboard to track model issues. By the end of this book, you’ll have learned how to develop a script to gather a model’s data and visualize datasets in Power BI easily.

Creating the first family placement script

Let's start by learning how to work with points and coordinates using Dynamo!

A point in Dynamo is an object made up of three numbers. Those numbers represent its X, Y, and Z coordinates. It's that simple.

Open Dynamo and follow these steps to understand the theory we are discussing here:

  1. Place an OOTB node inside the Point.ByCoordinates workspace environment, as shown in the following screenshot:

    Figure 9.1 – Point.ByCoordinates OOTB node

    Ensure that you place the node that requires three coordinates and not just two (just X and Y), as it will be placed on a two-dimensional surface. Here, we want to work with three-dimensional points.

  2. Next, place the Integer Slider node. This node allows us to use a slider to move through a range of integers. When you place one, please copy and paste it two more times as we want to connect it to the three available coordinates of the Point.ByCoordinates node.
  3. Now, let...
