Quick answers to the most common questions.
The QuantX Takeoff web app runs at quantx.nomitech.com. For the Excel add-in, get it from Microsoft AppSource, or in Excel go to Home ▸ Add-ins ▸ Get Add-ins and search for “QuantX Takeoff”. It runs in Excel on Windows, Mac, and the web. Your Microsoft 365 admin can also deploy it centrally.
In the add-in, open the Takeoff tab in the ribbon and choose Sign in. A secure sign-in window opens for your QuantX Takeoff organization. Once signed in, the Views, Cells, and Actions commands become available.
Viewing and previewing shared workbooks is free — you can open a workbook exported from QuantX Takeoff and see live quantities and drawing overlays without an account. Creating and editing takeoffs, linking cells, and building bills of quantities require an active paid subscription. See the Get started guide for details.
The Excel add-in registers custom functions in the CELLBIM namespace — for example =CELLBIM.QTY, =CELLBIM.UNIT, and =CELLBIM.TITLE. They pull live values from your linked measurements and refresh automatically when the underlying data changes.
A #NAME? error usually means the add-in isn't loaded in that workbook, or the function name was typed differently from how it's registered. Make sure QuantX Takeoff is loaded (open the Takeoff tab once), and enter the function exactly as =CELLBIM.QTY — without any extra prefix.
The add-in couldn't reach the server. Check your internet connection and sign in again from the Takeoff tab. If you opened a shared workbook, the read-only share token may have been revoked — ask the workbook's owner to re-share it.
Most commands require you to be signed in, and some require an open project. Sign in first; then select a project from Projects to enable the measurement and action commands.
Live cells refresh automatically. You can also force a refresh from the Linked cells screen. If a value still looks wrong, confirm the measurement still exists in the project.
The add-in supports Excel on Windows and Mac (Microsoft 365), and Excel on the web. A modern, supported version of Office is recommended for full custom-function and shared-runtime support.
