Built my first ever Rhino

Built my first ever Rhino plugin! Meet the ColumnCenterlinePlugin — it instantly creates structural centerlines, labels, and dimensions from your column geometry. Took me 7 days, 37 bugs, and a lot of coffee. This started as a fun experiment, I just wanted to understand how plugins in Rhino actually work. I had zero coding background in c#, literally none. So I decided to dive into C#, Visual Studio, and the RhinoCommon SDK… and things got interesting real fast The plugin works like this: 1. You run the command ColumnCenterlineCommand 2. Input your layer name (e.g. “COLUMN”) 3. Choose your settings , extension length, grouping tolerance, circle radius 4. Watch it auto-generate the full grid!
