About

I’m Le Duc Anh Tuan, a software engineer at Tiong Seng in Singapore. I work at the point where a building model stops being drawings and starts being data.

Four things take up most of my time. Revit add-ins in C#, for the parts of documentation nobody should be doing by hand. Autodesk Platform Services, to get model data out of the desktop and somewhere it can be used. A Revit AI agent, so the model can be operated by asking rather than by clicking through dialogs. And Agent Drawing, which reads drawings and project documents and pulls out what actually matters in them.

Before Singapore I spent nearly three years at Arent in Tokyo, building Revit add-ins in C# and WPF that automated MEP work people were doing by hand — routing, clash avoidance, the parts of a model that are rules rather than judgement. Before that, at THE BIM FACTORY in Ho Chi Minh City, it was Revit plugins, Dynamo, and project tooling on Autodesk Forge.

This site is where I write that down. Usually because I went looking for it and could not find it.
