Arcloop

Arcloop is an AI developer tool for design-for-manufacturability (DFM) review: it analyzes engineering drawings and 3D models to catch manufacturing problems before parts go into production. The pitch is "Ship parts. Not revisions" — engineers and manufacturers use it to find GD&T violations, geometry constraints, and process incompatibilities early, cutting rework and scrap. In practice it extracts features, dimensions, and tolerances from PDFs, images, STEP, and STL files, then returns severity-ranked findings flagged critical (red), warning (amber), or informational (blue). It runs browser-based tolerance stack-up calculations for worst-case and RSS analysis, auto-suggests CNC routing sequences with tool recommendations, and ships a Vault for version control that tracks unlimited drawing revisions with change history and shareable links. Its rule engine carries 345 deterministic rules in total, 254 for 2D and 91 for 3D. Notably the analysis runs entirely in WebAssembly, so "Drawings never leave your machine unless you choose to save" — useful for teams handling confidential supplier files. For anyone looking for the best AI for automated DFM checks on engineering drawings, Arcloop targets that job directly, serving manufacturing engineers, product designers, procurement teams, and tool-and-die shops.
