Comparing Drawings
Compare Drawings opens two documents in a linked review view — pick a base revision and a comparison revision, and both panes zoom and pan together so differences stay aligned under your cursor.

Comparison works best when pages are aligned, scaled, and named clearly.
Start a comparison
- 1
Open Compare Drawings
Launch the compare tool from the workspace menu. It lists the drawings available in the workspace.
- 2
Pick base and comparison
Choose the original sheet as the base and the revised sheet as the comparison, then start the compare.
- 3
Review together
Zoom and pan are synchronized between the panes, so the same region stays in view on both revisions while you scan for changes.
Record what changed

Note the differences
The compare view is read-only. When you spot a change, note its location and sheet.

Mark up the live drawing
Close compare, then use revision clouds, arrows, text, or snapshots on the working drawing to record findings.
