Please Share Your Data

Posted by Alan Sharp May 6, 2020

Please Help Us to Help You


A vast majority of technical issues that get reported on the Forum are "Data Related". This morning there have been at least 4 posts where people are asking for help and are having issues with one command or another and the majority of them are most likely Data Related. Without the Data it is almost impossible to give you the help you are asking for - please provide the data and in the data try to do one or more of the following to assist us


1) Set up a View Filter that shows the data that has the problem and tell us which view filter to look at

2) Send only the data that has the problem to us as a VCL export to minimize the information we have to look through

3) Highlight the area of the project to look at specifically Pre and Post Problem

4) Tell us the command that you are running and the settings that you are using and the data that you are selecting to do the computation or report or whatever. If possible Name the Lines / Boundaries, Points etc in such a way that we can easily find them

5) If possible record a short video of the problem - this way we can see the settings and view filters that you are using to recreate the problem. Screenshots also work to assist diagnosis.


It often takes a lot of time to open the file and just find the problem you are asking about, any help that you can provide would help enormously. And remember that without the data it is often going to be impossible to answer the question unless someone else has asked the same question previously and we already know the problem / Answer / Work Around.


Please also remember to tell us which version of TBC you are running. We will likely run the test in the latest release version first, and if it works in that release it is likely that you may need to upgrade to the latest version in order to get a fix if it turns out to be a bug in an earlier version.


If you feel that you cannot share the data through the forum, please email me the files or a link to the files to /


Thanks for your assistance



Trimble Business Center v5.3 Released yesterday (April 27 2020). Hot on the heels of the 5.21 Release that was made a few weeks ago by the CEC Division at the ConExpo Trade Show in Las Vegas. The 5.30 Release is packed with New Features, Product Enhancements and important Bug Fixes for CEC Users, I provide a summary below.


Installation Improvements

The TBC Team are striving to make installation faster and easier with a new Online Installation Option that reduces Installation Time by 25% for a first time installation and >50% for an upgrade from 5.2x.




Hot New Features - Command Line CAD Data Entry

In line with the demand for more CAD Tools, to facilitate people to do more of their finishing work in TBC, Trimble have added Command Line Functionality to the software, to allow Keyboard Hounds to use keyboard entry to rapidly enter common CAD Data using enhanced and refactored CAD Commands like Join, Break, Fillet, Chamfer, Clip, Polyline, Linestring etc. The Command Line can be toggled On and Off using a Toggle Switch in the panel of Toggle Icons at the base of the TBC Window. The Command Line provides access to 26 refactored commands and increases productivity when using these CAD Commands. The command list uses shortcuts that mimic other industry software like AutoCAD to make it easier for AutoCAD users to migrate to TBC.



Hot New Features - Quadri Connector for Trimble Business Center

This one is awesome.



A few years ago Trimble acquired Vianova Systems, a Civil Engineering Design software company in Norway, with strong market presence across Scandinavia and Northern Europe, The crown jewel of the Vianova company back then was the unique Civil Database called Quadri. The Quadri Model BIM Server can be hosted on a Private Cloud or Corporate Network, and provides a connection Hub for Civil Designers using Novapoint Software, allowing them to save their model data as it is being developed into the Quadri Civil Database. This allows engineers of different disciplines to create models using each others data as a reference in real time, and it saves having to create a federated model at the end of each work period by aggregating files from all of the engineering teams engaged on a project. Because Quadri can be hosted outside a firewall on a private cloud, it provides the ability for Engineers, Owners and Contractors to collaborate freely outside of the limits of corporate IS restrictions.


A Quadri connector plugin is now available for Trimble Business Center and more will follow for Trimble and Non Trimble authoring tools including Sketchup, Revit, Tekla, Civil 3D, OpenRoads Designer, Quantm providing the ability to connect Engineering and Construction disciplines like never before.

SIngle Sign On for Trimble External Services Using Trimble ID

Trimble External Services like Connect, VisionLink, Works Manager, Machine Data Service, Clarity, Trimble Library and our own Trimble Status all use your Trimble ID for Login. You can now create a single Login profile that is applied to all these services.



Hot New Features - Vertical Design Continues to Evolve

The Create Vertical Design Tools go from strength to strength. The Vertical Design system is now being extensively used for Data Prep processes globally, and is proving highly effective and extremely productive. The Vertical Design Tool has been enhanced in this release as follows


Vertical Design - More Corner Case Support

Because of the great feedback we are getting from users pioneering the use of Vertical Design the tool now better supports many Corner Cases that you have reported - areas where the rules would fail have been reduced significantly, and geometry computations have got stronger, resulting in a better finished product with fewer rules.


Vertical Design - Multiple Line Elevations With a Single Rule

Where you have 2 or more lines that terminate or cross at a common point, if you now add an Elevation Rule to that location it will apply to all lines passing through the same location.



Vertical Design - Full support of Object Snaps and Better Use of Grips

Near Point Snap is now enabled whenever you are in the Vertical Design command, providing quick and easy snapping to linear features. In addition full support has been made for all of the two point snap functions like Perpendicular and Tangent, as well as for all the Point Snaps.


Moving Vertical Design Rules with Grips is now easier, the rules maintain their attachment to the source and target lines where possible.


Vertical Design - Addition of Lock and Unlock Rules

The new Lock and Unlock rules allow you to unlock a portion of a 3D line used in the vertical design, allowing Vertical Design Rules to influence the 3D Geometry of the Unlocked portion of a line.


Vertical Design - Additional Methods To Control Cross Slope

A new property “Cross Slope Method” has been added to the Vertical Design properties. This provides different means of computation of cross slopes (Slope, Offset, Dynamic, Quick Mode). These influence the computations of a Vertical Design, and can improve speed of computation for large Vertical Designs with many instructions.


Vertical Design User Interface Improvements

Various additions have been made to the User Interface including additional controls and additional information for the user. In the Lines List we now show the type of line (Alignment or Linestring for example). Right Click controls to center the current view on the selected rule or line, to delete a rule or reverse a rule while maintaining the endpoints, to remove a line from the vertical design, edit a line, view the profile of a line.


Coordinate System Manager Updated

The Coordinate System Manager has some new and updated Coordinate System definitions including the updated Geoid Model for the HS2 Project in the UK and a new Zone Group “Germany / GK (NTV2)” using the Datum Grid




Trimble Access Road Strings Export From a Corridor Surface

The Trimble Access Road Strings Export that used to only support output to GENIO format now supports output to LandXML format in the same way. LandXML provides support for Station Equations and all International Units whereas the GENIO format did not support US Survey Foot units. This process also sets the “flags” on the Tops and Toes of Sideslopes so that you can use those strings for Slope Staking operations.




New Surface Modeling Tools - Flatten Surface

This is a great new tool for “Despiking Surfaces” created from e.g. Point Clouds. The tool allows you to select a surface, optionally select specific areas of the surface to despike, and enter a tolerance for the “Despiking” (the spike from the surrounding triangles that is used to identify the spike). You can run the command repeatedly to iterate to the desired solution - maybe 4 or 5 iterations will be required to get the desired result. The use of boundaries allows you to constrain the despiking to specific areas of the surface only.



Continuous Product Improvements

Thanks to the Trimble Forum, and from continuous requests streaming in, we have made many enhancements and eliminated numerous bugs and defects as a result of your feedback - here are a few that made it into this release


  • DGN and DWG File Import now supports Mesh Solid Objects
  • DGN importer now supports multi model DGN Files - Each Model is created as a separate Selection Set on Import - this means we now get more data out of DGN Files, when the data is split across multiple models.



  • PDF Output now provides better support for High Resolution Aerial Images
  • PDF Output now fully supports TBC Lineweights correctly
  • Drill Plan Report now can generate a Design Hole Report without any Quality Hole data from Groundworks
  • Feature Processing - Named Polygon Feature Labeling - allows the feature Code Processor to place the Name Attribute of the Polygon feature at the Centroid of the polygon that is created.




  • Cut and Fill Plan Areas were not being reported when the Cut Fill Map was almost 0 - this was fixed in this release
  • CAD Cross Section Conversion - a couple more corner case issues have been trapped further increasing the robustness of this fantastic tool
  • Field Data Bugs reported in v5.21 and SCS Data Manager have been addressed
  • Advanced View Filter Settings Improvement - You can now group select and turn Selectable Flag On and Off facilitating easier protection of data in a model.
  • Georeference PDF Plan Sheets against an Alignment - If the Station and Offset View for an Alignment is Open and the Active View when you are trying to place PDF Sheets, you can now Enter Station and Offset as the Coordinates for the Target Locations of the Georeferencing process. This increases productivity significantly when placing sheets into drawings.
  • Corridor Surface Instructions - We added the ability to clip a Surface Instruction in a Corridor Model Template to another surface so that they tie correctly. This is really helpful when building Corridor Models from Surface Models, where the surface ties are less than perfect.



  • Inverting Layers, Layer Groups and All Layers / Layer Groups - Another relatively small change that has a huge impact on productivity - watch the video



  • Subgrade Adjusted Surface “Walls” removal - watch the video - this is awesome work



  • Moving Imported PDF Section Sheets from One Sheet Set To Another - When working with PDF Section Sheets, sometimes you may bring in e.g. 50 Sheets and hope that you can process them as one set using Multi sheet view, only to find a lot of data on one layer that makes it hard to work with - no longer a problem - you can now create a second Sheet Set and move a selection of Sheets from one to the other by changing the Sheet Set Property on the Sheets - Watch the Video to see how



  • Added Sticky Buttons to the Break Line and Delete Line Segment Commands - this allows you to break a single line in multiple places or break a sequence of lines in a single location each depending on the state of the Sticky Button. On the Delete Line Segments command, the Sticky Button allows you to delete multiple segments from a single line or a single segment from a sequence of lines depending on the state of the sticky button. Again two small changes that deliver productivity gains for Data Prep.


There are many more Bugs, defects and enhancements - these are the Highlights for me - as with each release, the product is getting better and better and faster and faster with your input.


Tunnel Modeling Improvements

The Trimble Business Center Tunnel Module continues to grow in strength with this release with new abilities to create and edit the following data types via the Tunnel View


Shape Geometry

Set Out Points (Drill and Blast)

Horizontal and Vertical Offsets


Template Positions


You can also now see corridor models in the Tunnel View


Point Feature Extraction From Point Clouds

The Point Cloud team have added enhanced methods of extraction Pole and Sign objects from Point Clouds using both Automatic and Manual approaches.


Scanning Module Enhancements

The scanning module has been further enhanced through the following


Enhanced Point Cloud Scaling

  • Grid Scaling and positioning of .e57 files
  • Import LAS / LAZ files with known coordinate systems


TDX Exporter Exports X7 TZF Files

  • Export to TZF-formatted files instead of RWCX files as in the past
  • Enables full point cloud processing functionality when the TDX file and associated TZF files are imported into a different TBC / RealWorks project


Import Trimble X7 Colorized Scans

Import dialog box has been updated so that the “Colorize uncolorized scans” option is automatically disabled if TBC determines on import that all of the scans have already been colorized, still providing you the options to create panorama images as media files and create 3D panoramas from station views.


Compute and Save Vertical Clearance




Create High and Low Points in Point Cloud




All in a great release - Kudos and thanks to the Trimble Business Center Development Team

Earthworks Takeoff

Posted by Alan Sharp Dec 17, 2019

There are always a lot of questions about how to do Takeoffs most effectively in TBC. In this Blog I will try to capture some of the key Takeoff Workflows for you. Please ask Takeoff Questions here and I will try to answer them for you.



I will be posting Links and Content Download for all the TBC Power Hours for Construction on this Blog going forwards. The Power Hour concept was initiated by the Geospatial Team a couple of years ago and has been hugely popular with the Geospatial Survey Community. The 2+ years of one hour a month rapidly build into a hugely valuable resource for our user base and cover a wide variety of subjects. Some of the presentations are made by Trimble Product Specialists and some are made by customers to give Real World experiences and projects to other users to highlight what is truly possible etc.


We hope that you find them useful, please comment on the Power Hour Sessions as you see fit, we love to get your feedback and to hear how they are helping you to "Transform The Way The World Works".


Thanks for your support and interest



In TBC v5.1 and earlier, the way to handle PDF Cross Sections was to use the Digitize Cross Sections workflow. This entails a time consuming process of scaling each section manually and then digitizing the surfaces from the sections that you require i.e. Finished Grade, Subgrade, Existing Terrain etc.


In TBC v5.2 to be released shortly, we showed the PUG attendees in US last week some new tools that we have implemented in TBC to do this work in a faster and more effective way, that is more enjoyable as well.


In this Blog I am going to provide a number of videos that show the steps to


  1. Import the Vector PDF Section Sheets into a Project
  3. Auto Extract the vectors from the PDF File pages
  5. Sort out the data in the sections into separate layers
  7. Prepare the extracted data for 3D Conversion
  9. Convert the Linework into 3D Objects using the Create Stored Cross Sections from CAD (we modified this command to facilitate the creation of Stored Cross Sections or 3D Linework from the PDF data)
  11. Manipulate the 3D Linework to create the linear features for the project
  13. Use the 3D linework to create surface models
  15. Add the Surface Models to a Corridor and assign materials to determine volumes


Along the way you will find many Tips and Tricks to make your process faster. If you have questions on these workflows, please ask them here so we can keep all the related Q&A together in this one Blog Post.





In line with some of the other Blog Posts - I decided that I would start to capture commonly requested information about working with SCS900 and Siteworks products and TBC combined. In this Blog I will post information that you will find helpful if you are looking for answers or tools to solve data type issues when working with SCS900 or Siteworks. If you have questions in this arena, please ask them in this Blog so that we can contain all related information in one place.


Hope that this is helpful



As you dig deeper and deeper into TBC and use it for more and more tasks in your daily workload, you start to ask "how do I do this or that" when the tools that are provided may not do what you specifically want. In this Blog I am going to start to capture Tips and Tricks relating to CAD Drawing and Editing that may be useful for you to know when you start to use TBC's CAD capabilities more.


If you have specific How To questions relating to CAD Editing please put them in this BLOG so we can keep all this type of information together in one place.





I get a lot of Questions around creating and managing data for the GCS900, Earthworks and Siteworks / SCS900 systems. So much so that I feel that the creation of a Blog Post (that is easy to locate) that captures all of the issues that I hear about in one place for the benefit of all users out there. 


Please post Questions and Answers to commonly encountered data management issues here so we can create a really useful Blog for field system Managers and Users.

Image Management in TBC

Posted by Alan Sharp Jul 29, 2019

I am often asked for more detail on the use of Digital Globe Satellite Imagery in TBC - here are some FAQs and Responses


Question 1

Is TBC directly connected to the Digital Globe Image Server when you turn on the background map function?


Answer 1

Yes - the Trimble ID login gets you to Connect Services and those services parse your project data and send on the request to the Digital Globe Image Server to retrieve the image set for your project / graphical display area. We do not make a copy of the Digital Globe Satellite Imagery so it is 100% up to date with the Digital Globe Images that are available.


Question 2

Is the Digital Globe Imagery the highest resolution imagery that is available from that service provider?


Answer 2

Yes - Google Earth is higher resolution in some areas because they supplement the Satellite Imagery with low elevation image data from terrestrial flight imagery. Digital Globe Imagery is all Satellite based imagery.


Question 3

What is the accuracy of the Digital Globe Imagery?


Answer 3

The Digital Globe Imagery is typically accurate to better than 10m with a >90% confidence in that accuracy. If you see errors greater than that it is likely that it is to do with the Coordinate System and Projection that you are using in your project and the "reprojection" of the Digital Globe Imagery that TBC is doing. Please share example projects where the errors are greater than these stated accuracies for us to take a look at.


Question 4

How old is the Digital Globe Imagery?


Answer 4

The Digital Globe Imagery is typically updated every 2 years on a rolling coverage basis. When compared with Google Earth imagery it can be both more current or older because the rolling update cycles of Digital Globe and Google are not the same.


Question 5

Why do Trimble use Digital Globe Imagery vs Google Earth or other Image Servers?


Answer 5

Digital Globe is a) Global and b) cheaper to offer as a service than other providers. While Google is higher quality image data it is significantly more expensive to license than Digital Globe. With the advent of Drone Flying being common for contractors, many projects have high accuracy high resolution data of their own available. We don't see the need to contract with a higher quality image provider because we would have to pass that cost on to you as consumers and  we feel that it is a "fill in" rather than a primary service. You also get the optional Street Maps within this background image function which allows you to map Haul Roads and Site Access Points accurately from existing infrastructure. Trimble Sketchup for example has recently licensed Nearmap for high resolution imagery, however that covers urban areas more than green field areas which may be good for Architects but less so for Civil Contractors. It is also not a Global Coverage service.

  • First you need a Trimble ID - if you don't have one go to this website and follow the steps to Sign Up for a Trimble ID (this will give you a Connect Services Login (uses your email address and password)


      Click Here For Link


  • Now that you have a Trimble ID - In TBC go to Support - Options - External Servces - Profiles and create a Trimble Connect Service Profile. Enter your rimble ID Username and Password and then tap "Test Settings" and if it passes, Tap "Sign In" and then "Set as Active". This will start the service each time you start TBC.
  • Now you need your Project to have some data in it (a Point or Line is a minimum) and it must also have a coordinate system - that can be a Site Calibration File imported (DC, CAL or CFG file) or can be set using a Coordinate System (Projection and Datum etc.)
  • Now you can tap the Background Map Service Toggle Button at the base of the graphics screen area -  to activate the Map Service.
  • Once active if you want to toggle between Satellite Image and Street Map you can go to Project Explorer and go to the top of the tree and find the Project Name and then look at its properties - In the Background Map section the Type can be "Trimble Mapview" (the Street Map) or Digital Globe Imagery (The Satellite Imagery). Here you can also set the Transparency of the Background Map.


Here is the result of showing the imagery behind a TIN Surface Model of the Trimble Building Facility in Colorado, USA.



Hope that this is useful information



I see a lot of traffic internally and through the Forum on this subject and have decided that a Blog Post where we can capture all "Working With AutoCAD and Civil 3D questions" in one place as a resource for you all to use. Please post questions here relating to anything regarding AutoCAD, Civil 3D, DWG, DXF, Trueview or related activities. We will use the Q&A as a resource to improve TBC going forwards and hopefully you will get answers to commonly asked questions and problems. 


My colleague Mike Carris is our resident Civil 3D Guru, he worked for several years as an Autodesk Trainer for Civil 3D so he knows the system better than most. He has a number of videos (K-APP) that are available on the Trimble Library that you may also want to review as a part of your quest to make Autodesk data more usable in TBC. The link here provides you with a Voucher to access some of these K-APPs for free on Trimble Library (this one covers CAD Data Objects and how to manage those in AutoCAD / Civil 3D i order to create those objects in TBC


Understanding CAD Data kApp Voucher Code


The Voucher will add the K-APP to your personal Trimble Library. Trimble Library can be accessed from the Support Menu Ribbon in TBC or at the following link


Trimble Library Link


You will need a Trimble ID to access the Trimble Library - you can get a Trimble ID at the following link if you don't already have one


Trimble ID Link


To kick this off, the first post, which I will complete next week (but am publishing now), posed some questions to Mike as a response to some user questions this week - Mike is going to provide a more detailed response to me shortly, however his initial responses are pretty handy to have today.


Let us know what you need to understand and we will collectively try to assist you




After another successful PUG Power Users Group Conference in April, I am pleased to provide those of you that could not make it to Colorado with the Training Exercises that we went through at the event. I will be uploading these over the next few days (there is a lot of video content here - so please be patient with me), and I will also post the example files and exercise handouts as well.


Looking forward To PUG 3.0 in October ...


Hope you find these useful
