Revision Comparison

Track Changes Between Drawing Sets

Compare drawing revisions to identify what changed between versions. Catch unclouded modifications and understand the scope of revisions quickly.

How It Works

  1. 1

    Upload Both Versions

    Upload your previous drawing set and the new revision. Match sheets automatically by sheet number.

  2. 2

    AI Comparison

    Our AI compares each sheet pair, identifying visual and textual differences.

  3. 3

    Change Classification

    Changes are classified by type: dimensional, material, layout, notes, and more.

  4. 4

    Difference Report

    Get a sheet-by-sheet breakdown of what changed, including unclouded modifications.

The Unclouded Change Problem

Design teams are supposed to cloud all changes between revisions. In reality, changes slip through unclouded. A dimension changes, a note gets modified, a door swings the other way, but there is no cloud to flag it.

This is dangerous. Contractors price based on one set, then build from another. If they miss an unclouded change, it becomes a field problem, a claim, or at minimum, a heated conversation about who should have caught it.

Articulate catches what humans miss. Our AI compares every element on every sheet, identifying changes whether they are clouded or not. You know exactly what changed between versions.
