Archicad Project Compare

Migrating your complex project to a new version? Or perhaps you’re having difficulties spotting small changes in your running project?

The new Archicad Project Compare is here to help. It checks and shows you what has changed between two project states by visually highlighting hard-to-notice differences.

Review whether your deliverables are a pixel-perfect match and ensure your project data hasn’t changed. Project Compare helps you continue working on your project with confidence that your outputs are consistent.

Archicad Project Compare is available for projects between any two versions (Archicad 25 and up).

To get started, you’ll need these two utilities:

  1. Archicad Project Compare add-on (for AC25 and up)
  2. Archicad Project Compare tool

Locate the desired OS version in the list below and download the package with both installers.
