ViewCompanion Pro

View, Annotate, Compare, Print, and Convert Technical Files

Digital Takeoff

ViewCompanion includes annotation tools for quick and accurate measurement of floorplans, drawings, and technical documents. Calibrate scale once and use snapping for precise length, area, and perimeter calculations. The counting tool lets you instantly tally items such as doors, windows, and symbols, and include all results in your Excel export.

Compare Revisions

ViewCompanion offers efficient file comparison using its overlay mode. Easily compare two revisions of the same drawing or document by placing them on top of each other with color-coded highlighting. Adjust colors and transparency to clearly visualize additions, removals, and modifications between revisions. When finished, you can export or print the comparison result with all highlighted differences included.

Merge Multiple Files into One PDF

ViewCompanion can merge multiple files of different formats into a single multi-page PDF file.
This makes it easy to combine drawings, scanned documents, and reports into one organized and easy-to-share PDF document.

Printing

ViewCompanion offers full printing support, including batch, n-up, and poster printing. Print your documents scaled or fit to page. Add custom watermark, banner, header and footer to the printed document. Print the whole document or only the displayed portion.
