Starting in TBC v4.10, the License Manager has a simplified interface to select a network server hosting your TBC license.  Here’s how:

If you are using a TBC license from a hosted server, such as one-seat from a ten-seat company license stored on a virtual or physical server within the network, TBC’s License Manager needs to be able to communicate and read the network server.  

Select the name of your TBC host server from the License server drop-down menu, click OK, and restart TBC for the changes to apply.

If you don’t see your TBC host server in the drop-down, use the License Support page on TBC’s website:

to review FAQs, Tech Tips, or the Sentinel HASAP License Introduction document.  If you’ve troubleshot as much as you can, contact your local Trimble Distribution Partner.

TBC v4.10 is released, have you heard?  Lots of new features like Projected Surfaces, Tunneling module, locking feature-coded geometry, post-processing SSF files, and more.  

Looking to upgrade your current version to v4.10?  With TBC’s perpetually licensed software model, your license warranty date governs what is the latest version of TBC that can be licensed.  For example, TBC v4.10 requires a warranty date of April 1, 2018 or later to license the new version and functionality.

To check your TBC warranty date, open the License Manager from either the Start Page or the Support tab:

TBC v4.10's Start Page - launch License Manager


TBC v4.10 Support tab - launch License Manager


In the License Manager, check the upper right entry called Warranty expiration.  This date is your warranty license date. You are eligible to license any TBC version with the editions and modules you’ve purchased with a warranty (or build) date equal to or before your warranty license date.

So in this example, I am eligible to license the editions and modules under Features Licensed for any TBC version with a warranty (or build, the terms are interchangeable) date equal to December 31, 2020 or earlier.

Ok, that’s easy enough to find, but how can I find the build dates of TBC versions?  Well, you’ll be prompted with the latest available version in the Check for Updates routine, also available in the Start Page or Support tab.

Or, you can check the version’s Release Notes.  The build date will always be listed among the first couple of pages:

Or, Trimble Geospatial Support maintains a Latest Versions list on the Support A-Z page with build dates for TBC and other Geospatial products:

Armed with this license warranty date knowledge, update to v4.10 today (download page here) or contact your local Trimble Partner to extend your warranty past April 1, 2018!

Have you checked out the TBC website lately?

We’ve added a lot of information to our site for both the prospective and current user and it’s all in one place… the TBC website!

For the curious surveyor looking for a survey CAD office software package, watch our two-minute overview video, learn about supported workflows, listen to colleagues describe and demonstrate their experiences, and download the latest version of the software.



To help get you started, download our workflow tutorials, review the feature matrix to learn more about each edition and module, or view or register for a TBC Power Hour, or link to our 193 (and counting!) YouTube channel tutorial, new feature, and update videos.

Check out our playlists of new features, workflows, and Customer Testimonial videos.

TBC - Field to Finish with Confidence.

Did you know that TBC v4.00 shipped with 44 pre-built reports (that the author could count) for you to confidently deliver survey coordinates, adjustment routines, volume quantities, and more?

Most of these reports are listed in the Reports > More Reports menu, as shown:

The reports not listed in More Reports are context-specific, such as the four REB reports, which are primarily used in Germany, and are located in their respective ribbons (REB reports are included in the Corridor tab, in case you are wondering).

Configuring reports, for example to toggle a report to display in the Reports menu drop-down or modifying the header or footer contents, is done in the Report Options menu:

In the Report Options menu, find all reports sorted alphabetically and editable settings below.  For example, the GNSS Loop Closure Results report, which is not included in the drop-down Reports list by default, can be toggled to show in the Reports menu:

In the Report Options for the GNSS Loop Closure Report options, header, footer, report settings, and report sections can also be modified.

If you are looking for more customized reports, check out the Customized Report templates available for you to modify in Microsoft Word *.docx format.  Templates available in TBC v4.00 are Alignment Geometry, As-Staked Points, Baseline Processing, Earthwork, Network Adjustment, Point Card, Point List, and Site Calibration Reports.

Use TBC’s reporting to deliver confident results to your clients!

TBC - Field to Finish with Confidence.


TBC works with raw survey data from your Trimble and third-party hardware, not just with *.CSV or X,Y,Z coordinates.  This means that TBC not only integrates data from different sources, like GNSS receivers, total stations, and levels, but also allows you to check, modify, and recompute the resulting coordinates from those different sources.

Let’s look at an example to illustrate TBC’s computation engine and the Point Derivation Report.  Check out Point 1000:

Zoomed in a bit more with some annotation detail, there are three measurements to Point 1000, a GNSS RTK shot from base station at Point 400, and two foresight total station measurements from Points 102 and RSCT_2.  

You can left-click on any of the colored vectors (blue for RTK, green for total station) and view the raw data properties, shown here:

Any of the text in BLUE color can be changed, for example changing the GNSS receiver measurement method or adjusting the observation’s prism type.  So many QA/QC options when working with the raw data, but I digress… on to the Point Derivation Report...

With Point 1000 selected in Plan View, right-click and select the Point Derivation Report from the context menu.  Alternatively, you can select, then right-click on Point 1000 within the Project Explorer and select the Point Derivation Report or with Point 1000 selected, click in the Reports drop-down from the ribbon and select Point Derivation Report.

An HTML-based report launches, which displays project, coordinate system, local site settings, and, alas, point derivation information!

All observations used to determine the resulting coordinate for Point 1000 show in the Point Derivation Report.  A closer look now shows the reported coordinate for Point 1000 and what observations TBC’s computation engine used to arrive at this coordinate, along with deltas, precisions, distance, and azimuth data.

For Point 1000, the Northing, Easting, and height values were computed using the RTK shot from Point 400 and the elevation is computed from the RSCT_2 resection station.  Armed with this information, you can now go back into the vector properties in TBC and enable or disable observations or toggle horizontal or vertical usage. Recompute the project using the F4 key and generate another Point Derivation Report to see how your manual edits or checks has modified the reported coordinate for Point 1000.  

The computation engine and its hierarchy and heuristics has an entire Power Hour session dedicated to it.  Check out the March 2016 Power Hour with Boris Skopljak and Troy Brown to learn how the computation engine calculates coordinates here:
