RatioLab documentation

Read the canonical RatioLab guides: installation, the desktop workflow, optional CAD integrations, local MCP and technical references.

First launch

1. Download RatioLab for your desktop platform.
2. Follow the installation guide for system requirements, signing limitations and first launch.
3. Choose a model, set dimensions, inspect the 3D preview and export your design.

Explore the guides

These English pages are built directly from the documentation in the same source checkout. Every build also refreshes the local full-content search index.

Installation

Installers, system requirements and first launch.

User guide

Workspace, parameters, gear and reducer families and CAD export.

MCP and agents

Local setup, tool contracts and MCP server limits.

Application updates

Update checks, release downloads and installation.

Autodesk Fusion

Optional Fusion integration, setup and transfer limits.

Development and builds

Source code, dependencies, native installers and verification.

Calculations and references

Conventions, nominal formulas and geometric analysis limits.

Hardware and assembly

Bearings, fits, standard hardware and dimensional references.

Input and output

Connections, member roles and mechanical limitations.

Kinematics

Motion represented in the preview and export behavior.

FDM printed shaft

Experimental eccentric shaft with two axial through bolts.

Variants and limitations

Generated variants, documented architectures and model limits.

Worm reference

ZA and ZI equations, generated geometry and verification limits.

Strain-wave reference

Prescribed deformation, generated ring and numerical checks.

Bevel differential reference

Independent inputs, configurations, geometry and kinematic limits.

Understanding the models

RatioLab includes ten gear and transmission families, including bevel differentials. The five interactive models on the homepage are illustrations of selected mechanisms. Refer to the user guide and technical references for supported configurations, equations and limitations. Nominal geometry and ideal motion do not certify strength, service life or manufacturing readiness.

SolidCraft, Autodesk Fusion and the local MCP server are optional integrations. The website and its documentation are static; searches run locally in your browser.
