# Compare sheets

> Compare two specific sheets.

Compare two specific sheets directly. Use this when sheet numbers don't match or you want to compare specific pages.

## What Happens Next

1. Blocks on both sheets are detected (if not already processed)
2. Blocks are matched by type and position
3. [Overlays](/cms-api/resources/overlays) are created for each block comparison
4. The job completes when all comparisons finish

Poll [`GET /jobs/{id}`](/cms-api/jobs/get) to track progress.

## Use Cases

### Mismatched Sheet Numbers

Compare sheets when numbering changed between revisions.

### Cross-Revision Comparison

Compare a sheet from revision 1 directly against revision 3.

### Selective Comparison

Compare only specific sheets instead of the entire drawing set.
