On-Screen Takeoff


  • Maintenance release, no new features in


    • Improvements to AutoNaming workflow and performance
    • Improvements to PDF performance and quality including improved conversion to TIFF times.


      • ON-2991/ON-3311 - some Count shapes were causing OST to "lock up" when they were moved around on the page.
      • ON-3078 - when OST and Quick Bid were on the same monitor, creating a Typical Group caused Quick Bid to pull into focus.
      • Improved how OST imports the Pages Grid when importing OSP Bid Packages and there are multiple image folder locations. 

      Known Issues

        • As part of the new Auto Naming workflow, we have temporarily disabled the Auto Naming Results dialog box, this will be reintroduced as the Plan Details Editor in the next update to On-Screen Takeoff with improved functionality. 
        • The MyOnCenter Tab is not compatible with Windows 8.1 and will generate an error. As Windows 8.1 is no longer supported by On Center Software, this will not be fixed. Windows 8.1 users may view the MyOnCenter Tab contents here: https://www.oncenter.com/getting-started-home . Be sure to review the System Requirements in Related Articles.
        • Sometimes, after duplicating a Condition, if the name is still in edit mode and you draw takeoff, the cursor will not follow your movements. Workaround: save changes to Condition name before drawing takeoff.
        • Rotating a linear takeoff object that is set to "3-point curve" causes it to recalculate with slightly different results. This will be fixed in an upcoming version of OST 3.98.
        • The Image Folder button on the Cover Sheet sometimes disappears when user hovers over the field, making it difficult or impossible to click on the button. (Bug# ON-4556)
        • Area Backouts within a Zone are shown as "unassigned" negative values on the Takeoff Tab (Case # 02171995) ON-4441
        • ON-4746 - navigating to the Takeoff or Worksheet Tab closes the View Window
