TPC Desktop 2018 R2

2018 Release 2: September 5th, 2018


Coordinate Reference Systems defined by ESRI Projection file

CRS Uses PRJ Files

GIS .prj Files

Sneak Peek (1:48)

TPC can now use GIS .prj files as the Coordinate Reference System for your survey.

Just select a .prj file and TPC will evaluate it to see if it contains the CRS information. If it does, you can use it to define your CRS.

Sneak Peek (2:44)

Now you can access projection sources, like, to find the projection you need. Export it as an ESRI prj file and you can use it in TPC.



Geodetic Computations with Local Grid

CRS required for geodetic computations

CRS Distance Type Mismatch

We added a new warning when you try to compute geodetics with a local grid.

In this situation, of course, nothing gets computed, because there isn’t a projection. The new warning explains why it works that way.





Set CRS to Imported PRJ File

If you import a shape file into a survey with a (no CRS specified) and that shape file has a PRJ file, TPC prompts you to use the PRJ file as the CRS for the survey. Now in your survey, you can easily work with the same transformation used by the shape file.



Min / Max Surface Contours

Sneak Peek (1:28)

You can now specify Minimum and Maximum elevations for contours. This lets you specify a single elevation for a FEMA elevation or restrict the contours to any elevation range.

Sort Drawing Layers

Sort Layers by Drawing Order

Sort Layers By Drawing Order

In the Drawing View, the Layers Dialog now includes an option to sort layers by their order in the drawing instead of alphabetically.

Drawing Data Manager

DDM Convert To Survey

DDM Convert To Survey

Convert to Survey from Drawing Data Manager

Here is another way to convert CAD objects to survey data. Just select the object you want, right-click and choose Convert to Survey.

Be sure to delineate the object in the drawing to make sure you have the right object.

Drag and Drop

Drag and drop layers / entities to change their drawing order or move entities between layers.

Delineate Blocks and Modified Survey Text

Want to find the survey text you’ve modified?

Just expand that node in the Drawing Data Manager and select the text object. Now choose Delineate in Drawing and you can see right where it is.

Do the same for any blocks you’ve used in the drawing.

This pretty much rounds out the ability to select any drawing object from the Drawing Data Manager and delineate it in the drawing. This is such a handy tool to have.


XRefs Store Reference to Survey

Once you reference an XRef to your survey, TPC stores the reference parameters (translate, rotate, scale) with the XRef so you can reload the XRef without re-referencing it to the survey.

Access the XRef as many times as you need to, but you only have to reference it to the survey the first time.

XRef Data in Drawing Data Managers

XReference CAD

XReference Information

TPC now includes XRef information in the Drawing Data Manager.

Just expand the XReference and you’ll find it’s filename, number of objects, scale and rotation, etc.

Expand nodes, like Scale / Rotate, to see even more information.

Remember, you can also right-click any object and choose Properties to see everything about that object.

Missing / Renamed Xref Files

Missing XReference

Missing XRef

If an Xref used by a drawing is not available or has been renamed, you can use the View, Display Missing Blocks/Pictures command to display its stored pathname. You will see something like {C:\Data\Drawing1.dwg}.

To locate and update the XRef filename or location, double-click the bracket text or right-click it and choose Properties. TPC opens the XReference dialog where you can Browse to the location of the XRef file.


Trimble DC7

We’ve added support for additional records in Trimble DC7 and DC10 files.

GPS Vectors, Stakeout and Mean Turned Angles (5:15)

  • 56 Survey Mask
  • 59 Quality Control 2
  • 67 GPS Vector
    • these are delta X,Y,Z in ECEF coordinates.
    • TPC now uses ecef / lla computations and delta x/y/z for the antennas to compute the vectors
  • 70 Ground Vector
    • We had been ignoring these if the From point label did not match current OP
    • We now add and OP and FS all the time
    • az,hd,vd from reference point to foresight
  • 71 Survey Event
  • A0 – Stakeout Point Design
    • part of 67, A0, A5 sequence
    • lists the design point being staked and the stakeout method
  • A5 – Point Grid Deltas
    • x/y/z offsets of point actually staked and measured are stored as raw data
    • offsets are measured to design
  • B6 Long Feature Code
    • these become the attribute of the current point
  • C4 Mean Turned Angle
  • C6 Quality Control 1
    • PDOP, HDOP, VDOP, etc.
  • C7 Instrument Precisions
  • D6 Lines
  • D7 Horizontal Arcs
  • E3 Rounds MTA Residuals

Import Details

If the Message View is open and you import data with the [x] Details option turned on, TPC imports up to 4X faster by grouping lines before updating the

Message View

Imported survey points

Import Summary Includes Points

TPC also adds a [Summary] section to the end of the details in the Message View and displays the total number of points imported.
