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.

Concatenating strings

In this section, we will learn how to work with strings. Let's start by saying that strings are one of the most common data types used in every programming language, and Dynamo is no exception. Strings are sequences of one or more characters, including letters, numbers, and symbols. As a general standard in computer science, strings consist of whatever set of characters as long as they have single or double quotes at the start and end. Take a look at the following example:

  • "This is a string."
  • 'This is another string, a longer one.'

To computers, those two strings are the same thing. And by the same thing, I mean the same data type. They belong to the same category of objects. This means that with those, you can perform certain types of operations. To give you an example, let's say we have two numbers, 9 and 14. If you write a simple formula like 9 + 14, and execute it, the computer will output 23 because it recognizes...
