LAS CAD

A desktop parametric 3D CAD application. Not publicly available yet.

In development

By Lawal Ayo, founder of LAS G Concept · Updated October 31, 2026

LAS CAD is a desktop parametric 3D CAD application being built by Lawal Ayo at LAS G Concept. It is in development and is not publicly available yet. This page describes what it is designed to do, so that nobody has to guess, and it will be updated when a public release is ready.

What kind of program it is

LAS CAD is a cross-platform desktop application (it runs on Windows, Linux and macOS using Electron). Its modelling is based on a genuine boundary-representation (B-rep) geometry kernel, OpenCASCADE, compiled to WebAssembly and wrapped by the replicad library. In practice this means solids, boolean operations, fillets, shells and STEP files are real solid geometry rather than triangle meshes, which is the difference between a CAD program and a mesh modeller.

Workspaces

LAS CAD organises its tools into workspaces that you switch between from a dropdown at the left of the ribbon, in the style of other professional CAD tools. Each workspace shows only its own tools.

  • Design: sketches, features, parameters, a timeline and measurement.
  • Assemble: insert components, add joints with limits, animate a joint, run an interference or clearance check and export the posed assembly as STEP.
  • Sheet Metal: base and contour flanges, edge flanges, hems, tabs and reliefs, with thickness, bend radius and K-factor, a live flat pattern with a bend table, and a flat DXF export at 1:1.
  • Render: appearances, studio environments, lighting presets and PNG export, plus a built-in offline CPU renderer for high-quality images.
  • Animation: exploded views and keyframe tracks for joints, exported as WebM, animated GIF or a PNG sequence.
  • Drawing: drawings of a part, an assembly or a sheet-metal flat pattern, exported to PDF, SVG or DXF.
  • Script: a JavaScript editor with bundled examples, for generating geometry from code.
  • Simulate: linear static stress analysis with a material library, fixed faces, forces and pressures, and von Mises stress, displacement and safety-factor plots.
  • Manufacture: 2.5D milling CAM with a tool library, toolpath preview, material-removal simulation and G-code output, plus mould tools such as draft analysis and core and cavity split.
  • Electronics: a schematic editor, a two-layer PCB layout with routing and design-rule checks, a 3D board view and Gerber and Excellon drill exports.
  • Generative: topology optimisation of a design-space body, exported as an STL.

Project data tools include a library of recent files, version history snapshots of a saved file with restore, a zip share option and a git-friendly save.

Honest status

LAS CAD is a large project built by one person, and it is still being tested and refined. We do not publish download links for it yet, we do not accept orders for it, and nothing on this site should be read as a promise of a release date. Features described above come from the project's own documentation and may change before release.
