Bild (Meru Delta)
Meru Delta is an AI CAD diff that compares revisions, detects meaningful geometry changes, and writes plain-language change descriptions that roll up into ECO approval packets.
What it does and how it connects
Meru Delta is Bild's AI CAD diff. It automatically compares two versions of a CAD design, detects meaningful geometry changes, and explains what actually changed, visually and contextually, so reviewers do not have to flip between models to spot small geometry updates.
Each detected change is highlighted directly in 3D and documented in plain language, with dimensions, faces, and features, and no manual redlining. The page states Delta compares geometry, features, assemblies, and context, and shows added, removed, modified, or moved geometry with AI-generated explanations.
Delta plugs into the engineering workflow through APIs: upload two revisions and it identifies changed geometry, summarizes updates, and creates structured documentation. Detections bundle into a change order automatically, giving reviewers a complete picture before approval, which the page presents as one-click approval packets.
Alternatives
Compare side by side- CoLab (AutoReview)
A CAD review workspace with AI peer checks and tracked issues, rather than a revision diff that explains what changed between two CAD versions.
- LEO (Leo AI)
An AI Inspector that reviews assemblies for geometry, interface, tolerance, and GD&T issues, rather than diffing two revisions of a CAD design.
- Tandem
An AI-native platform that links requirements, CAD changes, and validation evidence across a program, rather than a diff of two CAD revisions.
- Werk24
A drawing-reading API that extracts dimensions, tolerances, GD&T, and materials from 2D drawings into JSON, rather than a 3D CAD revision diff.

- Pricing: a 600 USD figure appears in the page metadata with no plan, billing period, or context, so no price is stated.
- Real user voices: the only quote on the page is vendor-published and undated, so no voice is quoted.
- Related Error Index entries: no matching entry verified, since no CAD system is named on the page.
- SolidWorks and Creo as supported CAD systems: the Delta page describes uploading two CAD revisions without naming supported systems, so software is not stated.
