Compare revisions. Catch every bar. Pay once.

RevSight lays your old and new drawing revisions on top of each other. Removed work shows in red, new work in green and anything unchanged in black, so nothing slips through between revisions. Compare a single sheet, or a whole set of drawings in one pass.

RevSight overlay of two revisions of a slab placing drawing: removed bars in red, added bars in green
REAL OVERLAY · RED = ONLY IN OLD · GREEN = ONLY IN NEW · BLACK = NO CHANGE

A missed revision becomes a re-fabrication. When a bar is added, dropped, lengthened or moved between IFC and the latest issue, it is easy to miss on a busy sheet, and it reaches the shop as scrap and rework. RevSight makes every change impossible to miss.

  • Compare whole sets at oncePick the old and new issue. RevSight reads each sheet's drawing number and overlays every matching sheet automatically.
  • Nothing slips throughAfter a set compare it lists drawings found in only one set, and warns about scanned sheets it can't read.
  • Instant colour overlayOld in red, new in green, unchanged in black. One look shows what the engineer changed.
  • 3-point alignmentSheets plotted at a slightly different position or scale? Click three matching points and they snap together.
  • Swipe compareDrag a divider across the sheet to see the old drawing on one side and the new on the other.
  • Save & shareExport the overlay as a PDF to mark up, email to the checker or keep in the job file. A whole set saves into one PDF.
  • Fast and lightOpens and zooms instantly. Saved overlays are a few MB, not the 100+ MB other tools produce.
  • Your coloursPick any colours for old and new to match your house style. Your choice is remembered.
