Python scripting in Salome allows us to automatically generate random particles or pores. With subsequent operations we are able to build composite or porous bodies for study in Code_Aster.

A verifiable engineering knowledge engine that turns technical documents, CAD models, and equipment data into structured knowledge for humans and AI agents.

Python scripting in Salome for auto-generating overflows and venting lines for die-casting and Thixomolding

Hardware resources for Kalmix GNSS products — datasheets, 3D models, pinout diagrams, compliance certificates, and drivers.

Analytical calculations (Mathcad), 3D CAD modeling (SolidWorks, STEP), and electromagnetic simulation (CST Studio Suite) of a microstrip transmission line operating at 1.015 GHz.

Python scripting in Salome for auto-generating runners for die-casting and Thixomolding

Split multi-gigabyte STEP/STP assemblies into smaller files without loading them into CAD or RAM

This project allows you to download CAD files in `.STEP` format. Currently, the app supports various types of gears, bearings, and fasteners.

Parse DIALux EVO project files (.dat/.evo) into type-safe Pydantic models with Python.

Single-file, in-browser STEP (ISO 10303) viewer — the example app for step-io

Your AI actually looks inside FreeCAD — diagnose red sketches, rebuild vendor STEP/STL parametrically, inspect holes and interference, make drawings, check printability, run FEM. 36 MCP tools.
