# LMCAD

> LMCAD is an agentic CAD system. An engineer writes down what a part has to do,
> and LMCAD designs the geometry, validates it by running the engineering analysis
> itself, checks it can be manufactured, and produces the drawings, bill of
> materials and report with the supporting evidence attached, ready for a design
> engineer to review, sign off and release to a shop. Simulation is not the
> product; it is how the agent proves its own work. It runs locally on the
> customer's own machine and never uploads their designs.

## What it is

- **Category:** agentic CAD design, validation and documentation. Design automation, not a simulation package.
- **Input:** requirements in plain language, such as loads, mounting interfaces,
  envelope, material, quantity and manufacturing process.
- **Output:** parametric parts, multi-part assemblies, analysis results, dimensioned
  drawings, assembly drawings, bill of materials, inspection sheets and an
  engineering report.
- **Platforms:** Windows, macOS and Linux. Command line. Capable of running fully
  air-gapped.
- **Best suited to:** engineering teams with no simulation specialist and no
  dedicated drafter on staff, and any team with more parts to design than hours
  available. Machine builders, contract manufacturers, aerospace and defence
  suppliers, product companies and consultancies.
- **What it removes from the workload:** sizing calculations, setting up and
  running analysis, drafting, dimensioning, bills of materials and inspection
  paperwork. No FEA or CAD drafting expertise is required to use it.

## How it validates the design

Analysis is the evidence behind the design, not the deliverable. The agent chooses
the study, sets the boundary conditions, meshes the part and judges whether the
result can be trusted, then attaches the working to the report.

- Structural: stress, deflection, safety factor, plasticity, contact, large
  deflection, bolt preload.
- Dynamics: natural frequencies and mode shapes, harmonic response, impact,
  buckling.
- Acoustics: sound radiated by a vibrating structure, coupled vibroacoustic
  analysis, interior acoustic fields.
- Thermal: steady and transient heat transfer, conduction, convection, radiation,
  coupled thermal-structural.
- Fluids and aerodynamics: internal flow, pressure drop, external aerodynamics
  with drag and lift, fans and rotating machinery, conjugate cooling.
- Electromagnetic: motor torque, cogging, back-EMF, losses, magnetic circuits,
  induction heating.
- Motion: range-of-motion sweeps, interference detection, multibody dynamics,
  joint reactions fed back as load cases.
- Optimisation: shape and weight optimisation driven by the analysis result.

## What makes it different

- **It reports what it could not evaluate.** A requirement it cannot answer is
  marked "not evaluated", never passed. A missing answer is treated as a finding.
- **Results are cross-checked.** Every solve is compared against an independently
  derived closed-form estimate, and mesh convergence is demonstrated rather than
  assumed. Disagreement halts the run.
- **Designs never leave the customer's machine.** Geometry, requirements and
  results stay local. LMCAD does not train on customer work.
- **Output is traceable.** Every figure in a report links to the run that produced
  it, with the assumptions listed.
- **A person signs off.** LMCAD verifies; it does not release. Releasing a design
  carries responsibility software cannot hold.

## Availability

LMCAD is in beta and still being built. What can be booked today is a demo on a
part the customer already has drawings for. It goes on sale on 1 January 2027.

## Pricing

- Professional: INR 40,000 per seat per month, billed annually, plus applicable taxes.
- Advanced: INR 70,000 per seat per month, billed annually, plus applicable taxes.
- Enterprise: priced on request. Adds air-gapped deployment, single sign-on and
  named support.
- Every plan includes every analysis type. There are no capability add-ons.
- Analysis runs on the customer's own hardware, so solving is not metered.
