What it does and how it connects

Varen-AI-CAD, also called Varen CAD, is an AI CAD modeling agent for Windows. A one-line requirement goes in, the agent researches and calculates, asks structured questions, and produces a BOM plan for the user to approve before modeling each part and assembling it. The output is real parametric CAD with an assembled STEP export, built as boundary representation geometry through OpenCascade 7.9.3, not an image or a mesh.

Delivery is gated on checks: geometry and collision checks must pass before a result counts as delivered, and the production_ready flag in every delivery report stays false. The README states the product is for concept design and rapid prototyping, not a SolidWorks replacement, with no complete 2D engineering drawing workflow or general assembly mate solver, and every output needs human engineering review.

The README states the product is in closed beta and free during the beta, with a formal release coming. It also states that since October 2026 the repository is a release and portal repository only, holding product documentation, the landing page and releases, with the source code removed and development continuing in a private repository.

What engineers report

  • After launching VarenCAD.exe, the UI at http://127.0.0.1:8001 shows only a dark blue background with no interface elements. I cannot access Settings, Model because there is no UI.
  • cad-cae-copilot

    An MCP-capable CAD and CAE workbench that writes real build123d geometry and continues into simulation, rather than an agent that plans a BOM and builds an assembled STEP.

  • tau

    A browser-based, multi-kernel CAD platform with a natural-language interface, rather than a Windows desktop agent with a BOM approval step.

  • cad-studio

    A native macOS CAD studio where the user's own coding agent writes parametric build123d scripts, rather than a Windows agent with a BOM approval step.

  • kernelCAD-web

    Agent-native CAD that keeps the design as editable .kcad.ts source with hosted MCP access, rather than a Windows agent with a BOM approval step.

  • voice-to-3d-print

    AI-first parametric CAD from chat or voice through to 3D-print preparation, rather than a Windows agent with a BOM approval step and STEP assembly export.
