This course is for people who want to do more with the Autodesk Revit building information modeling software.
You can do a lot of great things with Revit as it ships "out of the box" from Autodesk, but there are still many tasks that are repetitive, boring, and error-prone. There are also many situations where you can be more effective and productive if you can add additional functionality to Revit.
This course will cover a wide range of topics in the Revit API. Each topic will be taught by walking through a set of C# code samples that progress from the basics to more advanced concepts.
More content will be added to this new course in the upcoming weeks. If you see a topic that you like added, just let me know and I will try to make that addition.
Prompt the user to select an element and retrieve data from that element.
The "Exception Handling" lecture is recommended to learn how to handle the user pushing the ESC key during a selection prompt.
Get the elements selected in the Revit UI and use the API to set which elements are selected.
Find elements in a Revit model using filters by Class (such as Wall or FamilyInstance) and Category (such as Door and Window)
Find elements that are visible in a specific view.
Find elements whose bounding box is inside a 3D space defined by two mouse-clicks
Use LINQ (Language-Integrated Query) syntax to develop more sophisticated queries of elements in the Revit model
Create an external command using Visual Studio Express
Create family types, family parameters, and set parameter values
Find the TEMP folder and the My Documents folder, combine folder and file names, and find all files in a folder.
Read data from Excel into a Revit API external command
How to write Revit data to an Excel file in a Revit API external command.
Includes using the Process.Start command to open a file in its default application.
How to handle exceptions (errors) that occur while running your Revit API code.
How to write and reuse functions that make your code easier to update and maintain with fewer bugs.
What it means when a member of the Revit API is marked "obsolete"
Create a Windows Form dialog to allow the user to enter information that will be used by an API command
How to modify the Revit Document and delete an element
Create a text note
How to check the type of a parameter (string, integer, double, element id) and set its value
Get data from a Revit element using Built In Parameters
How to create a Furniture family instance
Find the point or curve that defines the location of an element
Find area of faces of walls, floors, roofs, and other host objects.
Watch "Code Reuse" lecture to learn how to improve the code shown here.
Step Into a Macro to debug your macro code. Set breakpoints and create watches in SharpDevelop to see what is happening as your code executes.
How to prompt the user for a selection and only allow selection of specific categories
How to register an event to automatically run Revit API code when specific actions occur in the Revit session.
The DocumentSaving event is demonstrated in this lecture to show how to create and update a log file with the time of save and the user's name.
Create a ribbon tab, panels, and buttons with an external application
Store data in Revit elements that is accessible only via the Revit API
How to "see" in the Revit model by shooting imaginary arrows and finding out what they hit
How your API code can automatically react to user changes in the Revit model
This "lecture" will contain code samples to answer questions. This is being done because code formatting does not display properly in the Udemy Q&A interface.
Harry is the founder of Boost Your BIM, a software development and training company that collaborates with AEC firms to make Revit better. Boost Your BIM customers benefit from custom-built API applications that extend Revit’s capabilities and enable them to complete their work faster and with better results.
Boost Your BIM has built applications to automate routine tasks, enforce company standards, extract model data, use the Revit UI more efficiently, and solve other problems that would be difficult or impossible to do with Revit in its “out of the box” state.
Harry was an employee of Revit Technology Corporation and Autodesk from 1998 to 2012 and spent four of those years developing and testing new Revit APIs in areas such as the Family Editor, Massing, Analysis Visualization, Dynamic Model Update, and Views & Schedules.
