Secure MaxReader is designed to open, view and print individual CAL or TIFF files, as well as through a MaxView maxfr file.  The Secure MaxTakeOff software application offers the added tools for screen-based counts and measuring. Count and measurement takeoff information is stored as a MaxView document with the extension maxTK, thereby offering takeoff persistence.  Secure MaxMarkUp includes features in MaxTakeOff, plus enhanced annotation and markup tools to create Layer Templates and secure locked layers, all of which are saved with the revised document extension of maxMU. MaxView products can be purchased directly online through the MaxView Registration dialog box in version 3.10e or higher.
