2018 Release 0: January 3, 2018


This version of TPC is all about improving your workflows

We’ve taken a look at some of the most common workflows and asked, How can we make this more efficient?

This has led to fewer steps, greater consistency and better results in TPC Desktop 2018.

Here are some examples of how TPC is improving your workflows

  • An architect sends you a drawing that is 4 ft/in and your survey is in feet.
  • You get a GIS file that is in ground coordinates and you’re survey is in State Plane.
  • You want to bring GPS/GNSS data into your survey that’s on a local grid.
  • You’re reconciling a project you did years ago, before GPS with a new project.

We all run into these situations. We need to get everything on the same basis (position, orientation, scale, coordinates, etc.). It’s not quite as simple as calibrating just our field data to our survey. It’s real world. It’s more complicated.

That’s where our Reference to Survey comes in

Just pick points on the objects that correspond to points in your survey and TPC transforms that objects to your survey.

  • Import GPS / GNSS positions and reference them to your survey.
  • Import a GIS shape file and reference it to your survey.
  • Import a CADD drawing and reference it to your survey.
  • XRef a CADD drawing and reference it to your survey.

You get the idea. Bring just about anything into TPC and you can reference it to your survey. But expanding the ability to reference data to your survey is just one example of an improved workflow. Take a look at this release and you’ll find dozens more.

Drawing Groups

Reference Group to Survey**

Reference Group to Survey
 Reference Group to Survey (6:06)

Right-click any group and choose Groups / Blocks | Reference Group to Survey.

TPC will prompt you to select two pairs of survey / group points. TPC then rotates, translates and scales the group based on the points you selected.

Now you can use TPC’s COGO tools to check inverses, offsets, lengths, angles and anything else you want before you proceed with the project.

You might also want to move the group to a locked layer so that you don’t accidentally bump it back out of position.

Select Last Import**

Reference Group to Survey (6:06) (it’s one of the steps in this video)

You can select the last drawing objects imported into your drawing. From the Drawing View go to Edit | Select last import after you import data into your drawing and TPC will select those drawn objects.

Group Last Import**

Reference Group to Survey (6:06) (it’s one of the steps in this video)

You can now automatically group the most recently imported drawing objects. After you import data into your drawing right click one of those entities and go to Groups / Blocks | Group Last Import.


XReference Sneak Peek (4:00)

XRref Sneak Peek

XRef Sneak Peek

TPC now supports CAD XRefs. Changes to the referenced CAD file show up real-time in your drawing. Plus TPC doesn’t have store all the CAD entities in it’s drawings. It just stores the XReference and let’s it do all the heavy lifting.

Referencing an XReference to Your Survey

Referencing an XReference to a Survey (1:50)

In a perfect world, everyone works on your survey grid. In an imperfect world, they don’t. So you can scramble at the last minute to get the right coordinates or figure out how to change the ones you’ve got, or you can simply reference the XReference CAD file to your survey.

It’s easy. Just pick pairs of survey / CAD points and TPC scales, rotates and translates the reference CAD file to fit your survey.

You know how those architects are always sending you drawings in inches? Just reference to your survey and now they are in feet.

You know how the project is laid out on a local grid but you need State Plane for your GNSS equipment. Just reference to your survey.

This is a great way to get what you need right now.

XReference and Projects

So you are working on a large construction project with real-time changes. They’re ready for curb stakeout, but there are some last minute changes.

This is where XRefs shine. Let TPC update the XReference in it’s drawing and all the changes are right there. Just convert what you want to survey and stake it out.

XReference Layers

XReference Layers (2:55)

XRef Delineate Layer

XRef Delineate Layer

Sure you get an XRef for a project, but you have know idea what entities are on what layer. The contractor is ready to lay the electrical lines but you don’t even know where they are in the CAD drawing.

We’ve added some great tools to help you locate just what you need.

In the picture shown here, we’ve asked TPC to delineate the XReference|CURB layer. Now we can see what objects are on that layer and where they are. You’ll find other powerful tools, just like delineating layers, waiting for you in TPC Desktop 2018.

XReference Binding

XRefs and the Drawing Data Manager (2:10)

When you bind an XRef to a drawing, TPC replaces the XReference with the objects in the XReference. You lose the XReference, but you lock in the objects.

This is a great way to nail down a specific version of a CAD file to hang your hat on.

XReference Unload / Reload

Done with a CAD XReference for the time being? Don’t want to wade through it in your drawing right at the moment?

That’s easy – just Unload it. All the XReference objects go away, but TPC retains the XReference itself in the drawing. So when you want the XReference objects back in your drawing, just Reload it.

And speaking of Reloading, you can set an XReference to update automatically (default) when the reference CAD file changes, or you can tell TPC you want to update it manually. Then, when do want to update it, just Reload it. That simple.



Curved Leaders

Curved Leaders (2:10)

Curved Leader

Curved Leader

You can now draw Curved leaders in addition to angled leaders.

Drawing a curved leaders is just like drawing an angled leader, but instead of specifying an angle point somewhere in the middle of the leader, you just drag the cursor off to the side the create an arc left or right. It’s pretty simple and can add lots of pizzaz to your drawings.

Dot Leaders

Dot Leaders (2:18)

Dot Leader

Dot Leader

You can now end your leaders with a solid dot (circle) along with arrows and the other leader ends.

We’ve had a number of user say they like to use the dot-leaders to identify easements. Wow – what a great to keep your annotations distinct and consistent.


Drawing View

Polyline Areas

Polyline Area

Polyline Area

You can now compute the area of a drawing polyline from its Properties dialog.

Rotating an object to bearing**

Right click an object and choose Modify Objects | Rotate to Bearing to start the new rotate command. You have many options when choosing your To and From bearings. You can use snap commands, a single line, or a free hand points placed by a simple mouse click! Its a clean way to get a precise rotation.

Drawing View Undo

Any changes made to Traverse Drawing settings can now be undone. Changing color, font, linetype, label formats, symbols and decimals for Control Points, Curves / Spirals, Side Shots, Lot Labels, etc can be undone after they’ve been applied.

Changes made to Drawing settings can be undone as well. Leader settings all the way to Dynamic Offset settings can be undone after they’ve been applied.

Any scale change through the Drawing Settings, Scale bar or Zoom extents can now be undone.

Almost Black, Almost White

Almost Black And Almost White

Almost Black And Almost White

We added two new colors you can use as Black or White backgrounds for fills or clearing, without defaulting to CAD’s White = Black convention.

Black (almost) – draws as Black in TPC, regardless of background color, but reverts to Black when exported to CAD.

White (almost) – draws as White in TPC, regardless of background color, but reverts to White when exported to CAD.

Current Layers

Drawings stored with a survey file (.trv) now remember their current layer when the survey is saved and re-opened. They used to revert back to the 0 layer.

Select Values

Select Value

Select Value

Now when you use a COGO pick button [>] to pick a distance from a drawing object, TPC displays a list of values for the object. Just select the value you want and you’re good to go.

Block Reference Background Clearing

Background Clearing Overview (5:20)

You can now clear individual block references by turning on [x] Clear Background in their Properties dialog.

Move Not Allowed*

Tired of seeing the Move Not Allowed when you accidentally bump a traverse object like a line or a point symbol? Well, now you can go to the Program Settings and turn that message off.

Syntax Buttons

Syntax Buttons

Symbol and line type Syntax buttons*

 Syntax File Buttons (0:59)

We’ve added two Syntax Definition buttons to let you view how to edit symbol and line types. Clicking those buttons will open the default text editor with the syntax definition file for either editing symbols or editing line types.

More Repeats*

We added the Repeat option to more of your favorite drawing commands.

Want to insert multiple leaders? Just start the command and press R for Repeat. Save goes for circles, dynamic offsets and most of the other drawing commands.

Decimal Sizes*

Some dialogs, like the Legend Properties, didn’t let you enter decimal sizes using the keyboard. Now they do.

Text Object Properties*

When you right click a text object in a drawing and choose Properties, TPC now puts the cursor in the Text box where you edit the text.

Decimal Line Spacing Legends And Tables

Decimal Line Spacing Legends And Tables

Table and Legend Item Line Spacing*

You can now enter decimal line space factors. Add more line spacing to make the table easier to read or squeeze the lines together to fit more lines in.

In the example shown here, we’ve used a factor of 1.0 for the curve table and 0.3 for the line table.

Draw Backsights*

Draw Control Point Chain (3:04)

You can now draw backsights using Control Point Settings.

This lets you include your BS records in a drawing which can give you a better idea of how you ran your control and which control points you used in your site or topo survey.

New Point Symbols*

We have had several user requests for a few new point symbols so we have added them.

We now include over 130 point symbols with TPC.

Drawing Backsights**

Added [x] Draw Backsights (using Control Point Settings) option to the Advanced tab of the Traverse Drawing Settings. It draws BS records in the traverse.*

Drawing Templates

New Template Option*

Keep or Delete Existing Drawing Objects (1:31)

When you add a drawing template to an existing drawing, TPC used to remove any survey space objects from a layer in the current drawing if the template included that layer. So you had to create the drawing based on that template first, then add your survey objects.

Template Delete Objects On Import

Template Delete Objects On Import

Now, you can tell TPC whether or not to remove the existing survey objects when you import the template. You decide if you want to keep what’s already there or not.


CAD Polyfacemesh**

When exporting a surface from a drawing to a CAD file, TPC turns off the polyfacemesh layer. The CAD user can turn it back on if desired.*

Contour Labels**

Contour labels are now embedded into the contour lines when TPC exports a drawing to a CAD file.*

Contour lines with labels embeded now export at the contour elevation.*

When exporting a surface from a drawing to a CAD file, TPC now exports contours as polylines even if labels are being drawn.*

Drafted Lines**

Drafted lines like –[GAS]– are now written to the legend when TPC exports a drawing to a CAD file.*

Importing CAD into Drawing View**

  • most drawings scale and center automatically (a good Zoom Extents)*
  • turns off background clearing so large blocks and text don’t hide others*
  • background clearing is disabled for imported text boxes*

 Anonymous Blocks**

We added support for Anonymous blocks when importing a DWG file. These used to come in at 0,0. Now they come in where they are supposed to.*

CAD View

Send selected entities as group**

Send Selected Entities to Drawing View as a Group (1:33)

Select entities in the CAD View then right click and choose Drawing View | Send selected entities as group. All the entities selected will be sent over to the Drawing View as a group.

CAD View sending entities

CAD View sending entities

Send selected entities’ layers**

 Send Selected Entities’ Layers as a Group (3:49) (Same idea, but entities sent over aren’t in a group)

Entities from the unique layers of the currently selected entities will be sent to the Drawing View using the new Send selected entities’ layers command.

Example: if we have three entities: A which is on layer 1, B which is on layer 2, C which is on layer 1 and you select entity A and B then run this command, all the entities from layer 1 and layer 2 will be sent.

CAD View layers dialog

CAD View layers dialog

You can also perform the same task through the CAD View layers dialog. Simply open the Layers Dialog and click Send to Drawing View.

Send selected entities’ layers as group**

Send Selected Entities’ Layers as a Group (3:49)

The new Send selected entities’ layers as group command works exactly like Send selected entities’ layers command, except all the entities sent to the Drawing View are sent in a single group.

Undo last send selected**

Undo Last Send Selected (1:35)

If you don’t get the results you want when you send entities from the CAD View to the Drawing View, you can always undo the last send selected and try it again. You will use the Undo last send selected command for this.

Transfer Selected Entities to Drawing View*

Select some entities in the CAD View and right click and go to Drawing View | Send select entities… they will all appear in the Drawing View just like they were in the CAD View.

Convert to Survey*

CAD View: Convert to Survey (4:08)

Converts the selected entities to survey space. If you have multiple objects selected you’ll be asked if you want to create a traverse for each object.

Isolate a Layer*

The CAD View layer dialog now allows you to isolate a layer. The CAD drawing will automatically update to display only the isolated layer, until the layer is restored.

CAD View Block Properties

CAD View Block Properties

Entity Properties*

CAD View: Access and Edit Entity Properties (2:10)

Select then right click any entity in the CAD View and choose Properties to display a dialog for that entity.  Edit the line type, pen width, color, layer, etc.. For text entities , you can even edit the text. It all works pretty much just like it does in the Drawing view.

The Edit Codes button gives you access to all the DXF codes.

Remember, in the CAD view, you are editing the native CAD file itself. So you can make changes and send it right back to the client.

Documentation for Layouts*

TPC’s CAD View let’s you see any Layouts stored with the file. But layouts come with some rules. Things you can and can’t do because they are CAD layouts. We cover these rules now in the help topics.

Drawing Data

Delineating Drawing Objects**

Delineating Objects (3:15)

Delineate Objects from Drawing Data Manager

Delineate Objects from Drawing Data Manager

Delineating drawing objects from the Drawing Data Manager is one of the best tools you never knew existed.

So the problem with so many surveys is that they don’t happen all at once. I finally get back to a job I am working on and can’t remember quite where I put things. Or maybe a get a CAD drawing from a client and just want to figure out where they put stuff.

That’s when you want to delineate objects from the Drawing Data Manager.

Just expand any section, layers, traverses, fonts, XRefs, or whatever, and tell TPC to delineate it in the drawing. Wow! Now you see it. Select any other object in the Drawing Data Manager and it gets delineated. It’s a fast and fun way to see just what is where in the drawing.

Delete Unused Blocks**

Unused Blocks Removed

Unused Blocks Removed

Now you can delete unused blocks from a drawing. This reduces the size of the survey file and speeds up the survey file access time.

You can end up with unused blocks after importing a CAD file.

Closure View

Closure View Warnings Option

Closure View Warnings Option

[Warnings] Section*

The Closure View now includes a [Warnings] section you can turn on or off like you to the other sub-sections in the view. Just select View, Include Closure Data.

Friendlier Refresh*

The Closure View does a better job now of refreshing only when it has to. So as you switch back and forth, from the Closure View to other views, the view and the cursor stay where you left them (it used to scroll the entire view and put the cursor back up at the top).


Projection Files**

Import Geographic Shape

Import Geographic Shape

Importing Shapes with Projections (3:17)

TPC now looks for projection (.prj) files when importing shapes. It creates a CRS (coordinate reference system) using the information in the projection file and transforms geographic positions into to their corresponding coordinate positions automatically.

Geographic Shapes**

Import Geographic Shapes Without a Projection File (3:15)

If your geographic shape files doesn’t come with a projection file, TPC asks if you want to read it as geographic positions using the CRS of the survey.

Reference Shapes to Survey**

Take a look at the Reference Group to Survey in the Drawing View tab. You can do this with imported shapes too.

So lets say you get a shape file that doesn’t have a projection file and it doesn’t quite match your current survey. Just reference it to the survey by picking two point pairs and TPC will rotate, translate and scale the imported shapes to match. Just what the projection file would have done.

GIS Coordinate Systems**

TPC now supports 1) geographic, 2) projected and 3) local coordinates when importing and exporting shape files.


TPC reads the geographic positions and transforms them into coordinates based on the GEOGCS tag in the projection file and the surveys Coordinate Reference System.

You can also tell TPC to export shapes with geographic coordinates. TPC write the appropriate projection file with the GEOGCS tag.


TPC reads the projected coordinates and uses the PROJCS tag in the projection file to generate their equivalent geodetic positions.

You can also tell TPC to export shapes with projected coordinates. TPC write the appropriate projection file with the PROJCS tag.


TPC can also import and export shape files without projection files. These are just coordinates that the user can use with or without a CRS.

GIS Layers*

When importing GIS data into a drawing, objects now are added to the current layer instead of layer 0.*

 Importing GIS Objects Onto the Drawing’s Current Layer (1:35)

When you import GIS objects into a drawing, TPC now adds them to the drawing’s current layer. Just select the layer you want as the current layer for the drawing, then import your GIS file.

You can import any number of GIS files onto any number of drawing layers this way.

Import GIS Onto Current Layer

Import GIS Onto Current Layer


Tangent Intersects

Tangent Intersect Preview (3:06)

Tangent-Tangent Intersect (3:05)

Tangent-Tangent Intersect

Tangent-Tangent Intersect

Tangent intersects are regular intersections with the added constraint that they must be tangent to some arc, curve or circle. In surveying, we run into these when do don’t have a starting bearing to work with. We just know that we want the intersection to be some distance from a particular point and passing through some other part of the survey.

In the drawing shown here, TPC created

  • INT1R which is tangent to the curve from 3PC to 3PT
  • INT2R which is tangent to the curve from 7PC to 7PT

Of course there are lots of variations for computing tangents through a point, allowing intersects beyond the end points of a line, so no matter what information you start with, TPC will compute the tangent intersect you need.

 Horizontal Curve Dialog

Entering a negative Radius, Delta or ArcLength will also set the curve direction to CCW (Counter Clock Wise). Entering a positive value for these variables does not alternately change the curve to CW (Clock Wise). This is just a convenient way to enter a value and change the curve direction at the same time.

 Offset From Alignment**

You can now do Offset From Alignment with selected points from the Points Manager.*


We’ve made two changes to the way TPC exports a surface to CAD*

Exporting Surfaces to CAD (2:33)

  1. The polyfacemesh layer is turned off by default. You can simply turn it back on if you want to see it.
  2. Contours with labels are now drawn as polylines, just like they are if labels are not included. Plus all contours and labels are set to their respective elevations.

If you view the surface in CAD using the perspective tools, you can use either the polyfacemesh or the contours. They both look great.

3D Perspective on Contours

3D Perspective on Contours

Point Codes

Label formats**

Label Fomats (Lines, Curves, Points) are now stored with point codes.*

We also added a [x] Use Drawing Formats toggle to improve the user interface.*


Importing LandXML Surfaces with Hidden Faces

Import Surfaces with Invisible Faces from LandXML (4:08)

Now when you import a LandXML surface, TPC honors the invisible faces. They don’t show up in the TIN, volume or slope computations and contours don’t extend into them.

Many CAD programs use invisible faces to define the surface border. In prior versions of TPC, you would have to create a border traverse to match. Now you don’t. The surface just looks and works the same as it did in CAD.

Hide Invisible Triangles

Hide Invisible Triangles

With the [ ] Show Invisible Triangles turned off (default) in the TIN dialog, you don’t see them. But of course, you can always turn the invisible faces back on.

Exporting Survey Foot**

When exporting LandXML files, TPC now specifies US Survey Foot (linearUnit=”USSurveyFoot”) vs International Foot (linearUnit=”foot”), based on the current CRS.*


Select Traverse PointsSelect Traverse Points

Now you can select all the points of a certain type in a traverse.

  • Did you create a bunch of side shots from a COGO routine that you want to get rid of?
  • Do you have a bunch of offset points you want to convert to side shots?
  • Did you accidently import Notes into a traverse and now you want to get rid of them?
  • Want to see where all your control points are in a big traverse?
  • Want to see which benchmarks you used in a control traverse?

You can accomplish all of these with the new Select Points options.

One Edit Applied to Selected Points

And once you selected the points you want, enter one value for distance, bearing, elevation, etc. and all the selected points get updated.

Select Traverse Side Shots

Select Traverse Side Shots

In the example shown here, we’ve selected all the sideshots. Now if we enter just one bearing or one distance, they all get updated with that bearing or distance.

Want to see how this can improve your workflows? Watch Parking Lot Striping (10:08)

Here are the values you can edit this way:

  • descriptions, attributes
  • bearings, azimuths
  • horizontal distances, vertical distances, slope distances
  • instrument heights, target height
  • elevations (entering an elevation for a point, protects that elevation)
  • ellipsoid height
  • setback types
  • point type

Note: Many of you have already been using this concept in the Point Manager where you can also update elevations and descriptions for multiple points at a time.

Traverse Closure Type

We added a Closure Type tab to the Traverse Properties dialog. Choose from Open, Close Loop or Closed Point to Point.

Total Station Data**

TPC can now handle F2 only foresights and side shots. It computes the equivalent F1 values and stores them in the SSM or FSM point.*

We added new option to some data collector imports and the Traverse View called ‘Draw Control Point Chain’ to better represent instrument stations and backsights.*

Traverse Reports*

Traverse Report: Save Report As… command (1:41)

Temporary Traverse Reports can now be saved as new reports.

Traverse reports have always been temporary. You generate the report, print it out or append it to the current Report View, but when you close the temporary report, that report is gone.

Well now you can choose Save As… or Save.., give the report a file name and save a copy of it. Edit the report as often as you like and choose Save… to update it’s file. After you close the Traverse Report, you can open the report you saved in the Report View and continue working on it.

Relabel Points

Relabel Points

Relabel Points*

We added the Relabel Points command to the Traverse View context menu so you can access it like you do in the Points Manager.

Legal Descriptions


Legal Description Decimals

Legal Description Decimals

Legal Description Decimals (2:17)

Now you can control all the decimals used in your legal description.

TPC rounds up/down to the decimals you specify. Use other options to control the text TPC produces for you.

Legal Description Curves**

Legal descriptions now start curves and spirals with the text “thence beginning a curve/spiral”, indicating that you are already at the beginning of the curve/spiral.*

We have lots more legal description enhancements coming in TPC Desktop 2018 (many of you have been asking for them).

Tasks Manager

Tasks Manager Format

Tasks Manager Format View (2:20)

You can now format the Tasks Manager by choosing Format View… F9 or pressing the F9 key. TPC will display the Tasks Manager Format dialog.

TPC Desktop 2018 - Recent Files in the Tasks Manager

Tasks Manager FormatFilename Options for the Recent File List

  • Filename Only displays just the filename the way it has been shown in previous versions
  • Drive:\Path\Filename displays the complete path and filename
  • Filename [Folder] \Path\ displays the filename first, without an extension, then displays the drive and path. If the drive and path matches one of the predefined folders, TPC replaces that portion of the drive and path with the folder name in brackets.

Import / Export

Generic Raw Geodetic

Generic Raw Geodetic

Generic Raw Data

We added some new data types to the Generic Raw Data CSV filter.

V – Vertical distance, y – Latitude, x – Longitude and z – Ellipse Ht


Carlson RW5 BP & GPS Records

TPC now reads Carlson’s BP records.

Carlson RW5 BP & GPS Data

Carlson RW5 BP & GPS Data

Here is an example of the raw data in an RW5 file. The BP record indicates a Base Station and the GPS record indicates a rover. TPC now reads the BP records, creating control points for each in the traverse.

Coordinate Shift

Both BP and GPS records can be followed by a –GS record that provides the coordinates for that point. If the coordinates have been shifted, they will not match the geodetic positions based on the survey’s CRS.

To accommodate this, TPC reads the geodetic positions of both records by default, but lets you switch to the coordinate positions by turning on the [x] Protect imported positions in the Settings dialog.

Carlson RW5 BP & GPS Records

Carlson RW5 BP & GPS Records

Here is an example of the Details report for this file. TPC shows you the coordinates from the RW5 but tells you they may be overwritten by the geodetic positions so you know exactly how you got all the data used in TPC.

Set Elevations to Zero on Import*

Some of you import coordinates from systems that use very large negative or positive values for missing elevations. A new option in the Import settings tells TPC to look for these extreme values and set them to zero. Limits in Program Settings will let you define the values that will be considered extreme.

Draw Control Point Chain*

 Draw Control Point Chain (3:04)

TPC now provides an optional way to look at your control point chain.

Draw Control Point Chain Option

Draw Control Point Chain Option

Turn on the option in the Import Settings dialog or you can also turn it on in the Traverse View, using Tools | Draw Control Point Chain.

TPC checks each control point, comparing the preceding control point with any BS records that follow. If they don’t reference the same point, TPC inserts a GAP before the control point, eliminating that control line from the drawing.

But this new option also turns on a new feature that tells TPC to draw any BS records using the Control Point Settings. So TPC removes the control lines you don’t want and adds the ones you do want.

Draw Control Point Chain

Draw Control Point Chain

Here’s a picture of the new backsight lines you get (circled).

Data Groups

Retain Collapsed Traverse Groups

Retain Collapsed Traverse Groups

Retain Collapsed Traverse and Drawing Groups

When a survey is saved and opened, TPC now remembers which Traverse and Drawing groups are collapsed.

Prior to this release, all groups were expanded when when a survey was opened.

In the example shown here, we saved the survey with the Parking group expanded. So when we re-open the survey, the Parking group is the only group expanded.

Parking Lots

Parking Striping

Parking Lot Striping (10:08)

Parking Striping

Parking Striping

We’ve added some great new tools that make repetitive operations like parking striping fast and fun in TPC.

See the Traverses tab for a complete list.

Point Codes

Label formats**

Label Fomats (Lines, Curves, Points) are now stored with point codes.*

We also added a [x] Use Drawing Formats toggle to improve the user interface.*


Duplicate User Line Types**

TPC now checks for duplicate line types a user might add to the UserLines.dat file. If found, they are renamed by appending 1,2 3,etc. to them.*

Surveys Store Local CRS**

Surveys can now store Local.crs in the TRV file. This allows users to establish US Survey vs International Survey Foot.*

US vs International Survey Foot**

We now expose this survey settings more places in TPC.*

  • COGO – dialogs that allow you to select distance, direction and units now also display the survey foot.
  • Traverse Format – the Advanced tab now displays the survey foot.
  • Task Manager – shows the survey foot setting for the survey’s CRS.
