Compare every revision, side by side.
Overlay, side-by-side, and slider canvases for floor plan PDFs. Tint the old plan blue and the new plan green, blend smoothly, or compare directly. Share the comparison by URL.
Load two floor plan PDFs (Rev A and Rev B) into BuildWize and toggle between three comparison modes. In overlay, the old plan is tinted blue and the new plan green, so differences pop visually on the same canvas. In side-by-side, both plans render in parallel with synchronized pan and zoom. In slider, a draggable handle blends between revisions so you can sweep across the change.
Each layer has independent pan, zoom, rotation, and page selection. Important when Rev B reorders pages or rotates a sheet. Multipage plans are fully supported. Share the comparison by URL: both document IDs encode into the link, so the recipient lands on the exact same view you saw. Works on desktop and iPad.
