Built for CATIA V5 engineers

CATIA V5 is used by hundreds of thousands of engineers at aerospace and automotive companies around the world. Despite its power, the ecosystem of learning resources and automation tools has always been fragmented — scattered across vendor forums, outdated PDFs, and expensive training courses with weak practical content.

Arclara exists to fix that. We curate and publish high-quality AI macros for CATIA V5, written by practising engineers, and pair them with technical books and expert-led video courses so you can go from buying a macro to understanding exactly how it works — and extending it yourself.

Why no account?

We designed Arclara so that it stores nothing about you. Purchases are processed entirely by Lemon Squeezy, who acts as the merchant of record and handles all payment data and receipts. We never receive your email address, payment details, or any personal information.

This means Arclara has no GDPR obligations, no cookie banners, and no data breach risk — because there is no data to breach. We think that is the right way to build a technical marketplace in 2026.

CATIA V5 focus

Every macro, book, and course on Arclara is specific to CATIA V5. We do not cover 3DEXPERIENCE, CATIA V6, or other CAD platforms. This focus means you can trust that everything here is tested, versioned, and relevant to your daily work.

All macros specify the minimum CATIA V5 release required (e.g. R19, R20, R21) and the scripting language used (CATScript, VBA, or Python). The description tells you exactly which workbench the macro targets.
