AI-first
An assistant in the app builds and changes the plant with the same tools you use, one undo step per answer. Claude Desktop, Claude Code and other MCP clients can drive LineRig too. The PLC program always stays yours.
LineRig documentation
The AI-first 3D plant simulator. Describe a line, drop in a drawing or lay it out yourself, then run it from your own PLC.
Find your way
Section titled “Find your way”Getting startedInstall the app, open a sample, Edit and Run, the camera.
Building a plantPlacing, snapping, attaching, stretching, the hall, undo and projects.
AI assistantLet Claude build and change the line with you, or connect your own MCP client.
PLC connectionSiemens S7-1200, S7-1500 and PLCSIM Advanced over PUT/GET, with TIA Portal settings.
Samples and exercisesFour ready plants from a first program to a whole end of line, with I/O lists.
CatalogEvery part with its PLC signals, parameters, units and limits.
What LineRig does
Section titled “What LineRig does”Real production physics
Belts never move: loads are driven only by friction, so they slip, queue, tip and jam like real ones. Cylinders have real force limits. Every effect has a measured test.
Your own PLC
S7 PUT/GET to PLCSIM Advanced, an S7-1200 or an S7-1500, from Windows or macOS. A signal mapping to %I/%Q/DB
addresses that exports as a TIA Portal tag table.
Fixed simulation clock
Physics steps at 1/120 s, independent of the frame rate, like a fixed I/O cycle. Plants with hundreds of parts stay smooth on a laptop.
See it move
Section titled “See it move”
The clips are recorded from the test line running with its demo logic in place of a PLC.
Edit, Run, Reset
Section titled “Edit, Run, Reset”| Mode | What you do | What runs |
|---|---|---|
| Edit | Place, move, rotate and configure parts; undo and redo; save projects | Nothing moves: display and selection only |
| Run | The plant is simulated; a PLC, the demo program or you (by forcing signals) control it | Simulation clock, physics, PLC exchange |
| Reset | Back to Edit: loads disappear, every device returns to its initial state | – |
The plant document is the only truth: Run builds the simulation from it and Reset throws the simulation away, so a run can never change what you built.
