Build-Ink

Imagine you could go to an empty spot - put on a VR headset, take Logitech Ink in hand and actually start drawing out 3D building model. Enhanced by AI suggestions. Export BIM to continue work.

Inspiration

I have a VR set and would have loved to prototype my house building with something like this. Now, with the modern AI LLM improvements this has been made easier to accomplish.

What it does

Build-Ink lets users put on a VR headset, use Logitech Ink to draw full-scale 3D building models in air/space, receive AI-powered design suggestions, and export directly to BIM (IFC) for professional workflows.

How we built it

We combined Unity-based VR interaction, real-time geometry processing, AI-assisted shape recognition and improvements suggestions, and a BIM export file. Freehand strokes are converted into structured architectural elements.

Challenges we ran into

The converting freehand movements into locked interactions they convert to. Then adding UI for AI suggestions in a non-distracting way.

Accomplishments that we're proud of

Workflow design for AI suggestions -> VR UI -> export to BIM.

What's next for Build-Ink

Collaborative multi-user VR, structural simulation, generative layouts, and deeper BIM integrations.
