T3CAD

T3CAD is an agent-driven electronics workspace, forked from T3 Code. It combines coding-agent conversations with KiCad PCB, schematic, Gerber, and 3D inspection across web, desktop, and mobile.

Open optional BOM, footprint, symbol, and EMerge / Analysis tabs inside the KiCad viewer. The BOM follows the project's saved KiCad settings. Antenna specifications can be prepared for the existing EMerge workflow; openEMS execution is not integrated yet. See the KiCad viewer guide.

Run from source

Install the repository's Node.js and Vite+ prerequisites, then:

git clone https://github.com/i2cjak/T3CAD.git
cd T3CAD
vp i
vp run dev

Use the pairing URL printed by the development server. vp run dev --share makes an isolated development environment available over your Tailnet. BOM, footprint, symbol, and 3D previews require kicad-cli on the server; Gerber previews require Python 3.

The fork retains upstream package names and connection protocols. Upstream T3 Code downloads and npx t3 do not contain these T3CAD additions. No T3CAD binary release is published yet.
