starts on a strip.
Type From → To in a grid. Ohmstead finds the fan-outs, builds the jumpered terminal strips, routes the schematic and prints the 11×17 set.
TB2 · Toolkit
Everything a wiring diagram needs
Color-coded signals
NFPA 79-style starter set, automotive types, and your own.
The Codex
A shared parts library. Add a part once, fork anyone's.
Connectors & cables
One row per cable, every pin mapped, bad mates flagged.
Automatic terminal strips
Fan-outs become jumpered TB strips in one click.
Nested subsystems
Collapse a cabinet to one block, or drill in.
Hard-edged routing
Orthogonal wires in their own lanes, crossings avoided.
11×17 PDF export
Zone grid, title block, sheet refs and a wire schedule.
