Factory layout and simulation — Add-ons — Library

Overview

Factory layout and simulation is a planned add-on for ModelCraft, BimCraft and PartCraft (roadmap row XE.5). It is meant to lay out a factory, balance lines, run a discrete-event simulation of flow through it, and check ergonomics. It is not built as an add-on: no command or panel works today.

Who it’s for

Industrial and manufacturing engineers who plan layouts and line flow (intended).
Planners who want to test throughput before they build (intended).

What you can do

Nothing works today: the add-on is planned. What is intended for row XE.5: layout, line balancing, simulation and ergonomics, using a discrete-event engine and a motion engine.

Methods and standards

The planned add-on sits on two engines, engine.des and engine.motion, which are developer-space and are not added by people. The discrete-event library lib/des has sources, servers with queues and breakdowns and shift calendars, conveyors, AGVs on a guide path and a people egress model. The motion library lib/motion covers kinematics and dynamics. Ergonomics is not described in either log. No app mounts them.

Data and sources

Planned: no data ships. Times and rates would be typed in by the person.

Verification

Not yet checked as an add-on: planned, no add-on test exists. The engines have tests recorded in docs/0.8-sessions/xe-motion-sim_PART_3.md: tools/des-test/test.mjs 116 passed, 0 failed and tools/motion-test/test.mjs 134 passed, 0 failed, run 2026-10-29. Nothing was compared with a simulation product.

Limits

Planned and not built. No host mounts the engines and no help line exists. Line balancing and ergonomics checks are not built in the engines checked. A simulation is as good as the times typed in.

Files and formats

Planned: layouts as models. Nothing is read or written by an app yet.

Get started

This add-on is planned (roadmap row XE.5). Nothing is installed or switched on today.
Follow row XE.5 in /roadmap-issues for its status.
Until then the simulation and motion libraries are engines only, with no command or panel in an app.

Discrete-event and people 700 KB
Motion 600 KB

Adding it brings these too. Engines are shared: each downloads once for every add-on that uses it.

Needed by: Industrial engineering (factory layout, workflow, ergonomics).
