What’s New


Larger Survey Files (3:04)

This release of TPC is all about speed. You can now work comfortably with larger surveys.

We developed this release using surveys with 10,000 to 100,000 points. Our goal was to identify bottlenecks where you had to wait for TPC to finish a task. We tackled the obvious ones first and have a list of others to address in future releases.

Example – 50K Point Survey

 Task                               X faster        (2016 R1 / 2016 R2 times in seconds)
Open survey                 9X faster        (41.2 sec / 4.8 sec)
Open Traverse View   93X faster        (65.0 sec / 0.70 sec)
Regen drawing         134X faster        (470.4 sec / 3.5 sec)

Example – 1.3M Point Survey

 Task                               X faster        (2016 R1 / 2016 R2 times in seconds)
Import 1.3M Points       71X faster      (1141.0 sec / 16.0 sec)

Virtualized Data

The Points Manager and Traverse View now open almost instantaneously, no matter how many survey points they reference.

We did this through what is called virtualized data. TPC retains more control over the data, providing information on just the part of the view that is open. The results are faster operations in just about every aspect of the view.

Progress Indicator

The status bar now tells you what TPC is doing and how many points it has processed. So if you have to wait for an operation to finish, you can at least see how TPC is progressing.

Start by opening a large survey and watch as TPC tells you how many points it read, how many lines it created, how many traverses and traverse point it loaded and so on. Open a drawing or a surface and TPC will show you the progress as it computes drawing objects, contours and surfaces.

Drawing Optimizations

Drawings happen a lot faster, thanks to some very specific optimizations. We identified the slowest drawing operations and optimized them. So a large drawing that may have taken a minute to render before, now takes just seconds.

Opening Large Surveys

When you open a large survey, TPC keeps track of the time it takes. If it takes too long, TPC provides some program settings for you, that will speed up your work. We explain these in a new help topic Working with Large Survey Files.

One of these is the new option to NOT open the current drawing when you open a survey. Without the drawing, you can still open traverses, check closures, generate reports and everything else TPC does. Then, when you choose, open any drawing.

What's Next

We have lots more optimizations planned for the next release of TPC Desktop. We plan on taking maximum advantage of all the processor cores in your computer and any SSD drives you’ve installed.  If you really want speed and have invested in a fast computer, we’ll be right there to take advantage of it.
