Delta · Design Change Intelligence

AI that understands CAD changes

Compare versions, visualize changes in 3D, and understand the intent behind every revision, without relying on meetings, screenshots, or manual notes.

— THE PROBLEM · 01

Engineering changes move faster than teams can understand them.

A single CAD revision can impact manufacturing, sourcing, tooling, timelines, and cost, but most teams are still reviewing changes manually.

Engineers flip between models trying to spot tiny geometry updates.
Review meetings become long walkthroughs instead of decisions.
Change notes are incomplete, inconsistent, or never written at all.
And critical downstream impacts get missed until it’s expensive.

Delta gives engineering teams instant visual intelligence for every design revision. It automatically compares CAD versions, detects meaningful geometry changes, and explains what actually changed, visually and contextually.

WHAT DELTA ELIMINATES The hidden cost of manual design reviews 01 Hours spent manually comparing revisions 02 Meetings centered around screenshots and guesswork 03 Missed geometry updates that impact manufacturing 04 Engineering changes buried in disconnected notes 05 Slower release cycles caused by unclear revisions

— FEATURES · 02

Delta doesn't just compare files, it understands engineering change.

Delta compares CAD revisions like an experienced engineer would, analyzing geometry, features, assemblies, and context automatically. Just upload two versions and Delta explains the difference instantly.

Visual Diffs

Delta highlights every geometric change directly in 3D, so reviewers see exactly what moved at a glance

----------------------
4.2x faster change reviews

Auto Annotations

Every detected change is documented in plain language - dimensions, faces, features - with no manual redlining required

----------------------
0 manual redlines

ECO Rollups

Bundle Delta's change detections into a change order automatically, giving reviewers a complete picture before they approve

----------------------
1-click approval packets

— WORKFLOW · 03

Every revision. Compared automatically.

Delta plugs directly into your engineering workflow through APIs. Upload two revisions, and Delta identifies changed geometry, summarizes updates, and creates structured documentation your entire team can understand.

Select two revisions

Delta automatically analyzes CAD geometry, assemblies, dimensions, and feature updates across versions.

Share changes across teams

Engineering, sourcing, manufacturing, and leadership all get a clear understanding of what changed without needing to interpret CAD manually.

The material that was removed is likely increasing the hole diameter from 3mm to 3.5mm. This change could have been a result of the y-vertical-rod.sldprt component increasing it's size. Screw-atta... Extended back wall and decreased hole diameters This change involves material that was added at center point (13.5mm, 7.00mm, 23.93mm). The material that was added likely increases the thickness of the back plate by 2.5mm. The 4 outer through-holes touching the back plate also decreased in diameter by 2mm. This... Screw-atta...

“When a revised design is shared, reviewers are often left piecing together what changed. Delta adds the missing context, giving our team hours back every week.
