TPC Desktop 2023 R0

Traverse PC is now 64-bit

Most computers you buy today are 64-bit. TPC has moved to 64-bit to take full advantage of them.


When moving to 64 bit, Windows apps typically get a 15% to 30% speed increase. You’ll notice it when TPC computes surfaces, Least Squares and graphics in general.

In the next few releases, we’ll identify any remaining bottlenecks and get them up to speed as well.


32-bit apps are limited to 4 GB of memory, but 64-bit apps can use all the memory you have.

This is a huge help for your larger surveys, but even smaller surveys that incorporate background photos in a drawing or use geoid heights will notice the difference.


Newer computers often have 16 or more cores, all of which can tackle their own computations. TPC 64-bit takes advantage of all the cores that are available.

If you typically multi-task, running TPC alongside your other programs like GIS and Google Earth, you’ll notice that TPC runs at full speed.

Traverse Layer Names

You can now segregate traverses in your drawing using Traverse Layers that used to be available only when exporting to CAD.

See Traverse Layers

Turn on [x] Use Traverse Layers in the Layers dialog as shown here.

Or open the Drawing Layers settings dialog shown below and turn on [x] Use Traverse Layers.

Drawing Layer Settings Dialog

See Layer Settings Dialog

This new dialog gives you access to the drawing’s layers settings.

Use the Traverse Layers options to turn on traverse layers and use or not use traverse group names for the layers.

Use the Point Labels options to create separate layers for point labels.

We’ll continue to add other drawing layer options to this dialog as we develop so setting are available in one place.

Traverse Groups do Layers

See Layer Settings Dialog

You can use your existing Traverse Group names for traverse layer names. Just turn on the [x] Use traverse groups option shown here.

Maximizing Smoothing

We’ve added a new [x] Max Curves toggle so you can go from engineered smoothing like contours use to something a lot curvier.

You’ll use this for riparian boundaries and more.

See Maximizing Smoothing

Smooth Traverse Sections

Now, in addition to smoothing an entire traverse, you can smooth just the sections of a traverse you want.

See Smoothing Parts of a Traverse

Smoothing a Traverse Section (5:5)

Drawing Codes

We’ve added two new Drawing Codes.

Begin Smoothing .BS

Begin smoothing at after this traverse point.

End Smoothing .ES

End smoothing after this traverse point.

Using Drawing Codes

We’ve added the [x] Use drawing codes to begin/end smoothing.

Turned On – use drawing codes

Turned Off – still does smoothing, but smoothes the entire traverse.

Available in Professional Edition.  Compare Editions

This new tool is for anyone that has experienced an issue with a drawing.

Viewing Warnings in the DDM

The Drawing Data Manager (DDM) now includes a Warnings branch that lists drawing objects that may have issues.

See Viewing Warnings in the DDM

Warnings are also included with objects listed in other branches like Layer and Picture.

Example Warnings

In this image, TPC identifies some text objects that have issues. The Text: “G” shown here has a negative height and is not on the page. You can fix it or delete it.

Add Attributes to Point Labels

For years, you’ve been able to choose what to include in point labels –descriptions, coordinates, geodetic positions, etc.

Now, you can also add point Attributes to point labels.

See Labeling Points.

Many of your data collectors store Descriptions and Attributes for each point. TPC stores both, and now both can be added to point labels.

Turn on [x] Attribute in the Control Points and Side Shots tabs (see right).

Then format the point labels and include the letter a in the format field shown below.

Creating Stations Without Offsets

Users often utilize the Station Offsets dialog to add stations on an alignment without adding any offsets. They figured it out with a little experimenting.

We wanted to make this common workflow more obvious and easier to use.

See Adding Single Stations

We updated the Station Offsets dialog to include some simple instructions on how to set the Offset distance to 0.0, which tells TPC to compute just the station. Plus, we added some prompts to let you know that TPC uses the station for the point label and when TPC decides that station already exists based on the station tolerance you specify.

In the dialog shown here, we entered a Station of 805+00 and left the Offset 0.0. TPC tells us that it now has a Computed Station.

Many of you have asked if we can ready your old Eagle Point Sofware files and extract the point nodes as survey points.

Well, beginning with this release, you can.

Watch the video to see how you can find and select the Eagle Point nodes you want to convert.

Available in the Professional Edition only.

Convert Eagle Point Nodes to Survey Points (5:50)

TPC creates a drawing group for each Eagle Point Node.

The group shown here is for Eagle Point node 401 and includes the insert point (Line), point label, point description and elevation.

New: Export Survey Space Only

Use the new [x] Omit Paper Space Objects to export just the survey space objects from your drawing to CAD.

Omit Paper Space Objects

New: 3 Point Circle

You have asked for a 3 point circle command like AutoCAD uses. Pick any 3 points and TPC draws a circle that passes through all 3 points.

See Circle command
