This is a Hot Fix to version, released 8/16/2019, to address issues identified post-release.

This version is being released to groups of clients, not everyone at one time. Check MyOnCenter.com to determine if your organization is ready to be upgraded.

Fixed in


  • Updated the address for the Auto Name servers to a Constructconnect.com URL (this may require additional configuration of your firewall, see Related Articles for details)
  • Removed the option to open the product when installation was complete - this caused issues when a user who was upgrading On-Screen Takeoff (OST) and Quick Bid (QB) launched OST before being able to upgrade QB.


  • License Keys and Server Codes that fail to activate are not removed from the historical list of codes in the Check Authorization dialog box.
  • Databases upgrade correctly from version 3.94 and allow users to add pages to existing and new bids. This addresses an issue where users upgrading to the original release of 3.96 from 3.94 experienced unexpected behavior when adding pages to an existing bid or creating a new bid. If you have previously upgraded a database to 3.96, installing this Hot Fix upgrades that database again and corrects the issue.

On-Screen Takeoff

New Features

  • You can now customize the appearance of the full-screen takeoff "crosshairs" by setting the thickness and color.
  • Added "Sheet No." field to Cover Sheet, Auto Naming dialog box, and Page Navigator.
  • Added option to show/hide the Page Number (the Page's position in the grid) and the Sheet No. (whatever you specify) in the Page Navigator.
  • Added ability to zoom in/out in the Auto Naming dialog box.
  • Added notification to the Image Tab advising the user when they are viewing a PDF that has not been converted to TIFF.


  • Added a button to Cover Sheet that opens the "Best Practices" article regarding Auto Naming.
  • Removed the option to convert PDFs to TIFFs on the Cover Sheet.
  • Add option to launch the application from the final screen of the installer.
  • Changed the "Enable Color PDFs" option to "Disable high resolution images" and disabled option by default (so all images will display, by default, in color at higher resolution).
  • Links in the MyOnCenter Tab now open in your default internet browser, not hard-coded to Internet Explorer.
  • Disable the "Change Folder" button when the Pages selected are not stored in the same folder (which prevents the function from working).


  • Index #'s that end in "0" could not be entered in the Cover Sheet Pages grid.
  • Adding a child bid on the Bids View tab in the Conditions Window caused all folders to expand on the main Bids Tab.
  • User could change the Style of a Condition that has been used to draw takeoff by typing in the Style box.
  • Auto Naming suggestions sometimes included invalid characters.
  • The Num Lock key toggles when user clicks to link a result to an Excel spreadsheet.
  • If Quick Bid has access levels enabled, users could not create interactive bids in OST.
  • Resizing a column in the Conditions list did not resize the header, just the column data. 
  • Numerous other minor bugs, never reported by users.

Known Issues

  • You cannot upgrade to 3.96 directly from version 3.94 or earlier. You must install OST 3.95 (available on the Product Information and Downloads Page, see Related Articles). Once installed, open any databases you use and upgrade to 3.95. Then, you can install the 3.96 upgrade. We are working to resolve this issue.
  • Licenses keys that fail to activate (no licenses available, invalid code, cannot connect), are removed from the historical list drop-down.
  • Area Backouts within a Zone are shown as "unassigned" negative values on the Takeoff Tab (Case # 02171995) ON-4441
