Recommendation: Take the CS50 Course from Harvard University, or the Free C# Course by BIMTeam on Stepik (by PIK), to build a solid foundation. True and False (true/false) In programs we often check conditions. For example: “if the pipe is longer than 10 m — make a joint.” A condition can only be either true or false. True and False (0 and 1) Computers don’t understand the words true/false — everything is stored as numbers. So true = 1, and false = 0. ...

This lesson delivers on the promise from Lesson 0 — we’ll build a real command that: Tries to create a sheet (with proper error handling) Counts existing sheets in the document Shows a friendly summary to the user ✅ Prereqs: Finish Lesson 0’s Application setup first. If your project has no title blocks loaded, the command will tell you and exit safely. Application vs. Command Application (starts with Revit): sets up your add‑in — e.g., creates ribbon panels and buttons. Think “wiring & menu.” Command (runs when you click a button): does the actual work — reads/modifies the model. Think “tool action.” In code, these map to different interfaces: ...

Why C#? Scalability Start with Install Visual Studio 2022 Community Install .NET SDKs (.NET4.8 & .NET8) Install Nice3Point Templates Project Solution Start a solution / project Create a new project Choose the Revit Addin (Nice3Point) Template Configure your new project Name of the project Location Solution Name - same as project name (it’s a folder name that holds many projects) Additional Information Add-in type -> Application User Interface -> None IoC -> Disabled Serilog support -> unchecked Keep it simple for now, you can change those settings later in the project. ...
