TPC Desktop 2022 R1

This release rounds out our calibration workflows with some great new tools.  Released 6/27/2022

Calibrate on Import

In TPC 2022 R0, we introduced calibrations on export.  Calibrations convert coordinates from any other coordinate system to your survey and back again.

This release lets you use calibrations when importing.  Use an existing calibration with any import type that support it and your data will come in calibrated and ready to use.

Calibrate from CAD View

What if your survey is on a CRS like State Plane and you get CAD plans that are at 0,0?  We take all the hassle out by letting you pick a series of points in the CAD drawing, then select those same points in your survey.  TPC creates the calibration you can use to XRef those CAD plans right into your drawing, right where they should be.

Create a Calibration for Scale & Base Point

Grid to ground conversions are often done with just a scale and a base point.  So we make it easy to create this specific calibration manually or directly from the Convert Coordinates dialog.

More Calibrate on Export Types

More of your favorite import types now allow calibration on export.

Released 1/31/2022

Import and Export with Calibration (6:16) – Many file types allow calibration on import and export.

We introduced calibrations in TPC 2019 R0.  They convert coordinates from any other coordinate system to your survey and back again.  TPC has been using calibrations for background photos, grid to ground, CAD files, GPS/GNSS and lots more.

This release lets you use calibrations when importing data.

Turn on [x] Details and TPC will report the original and calibrated coordinates for each point imported.

Calibrating From the CAD View (7:17) – When your CAD coordinates are very different from your survey coordinates, you can select a series of points in both the CAD View and the Drawing View to create your calibration.

Starting in TPC 2022 R1.

You can use the CAD View to create a calibration for a CAD File.  This method is essential when the coordinates in the CAD file are very different from the survey’s coordinates.

  • Choose Tools, Calibrations, Create Calibration to display the Create Calibrations dialog. 
  • Choose Select uncalibrated point sequence from the CAD View, then select their calibrated positions in the current drawing

Starting in TPC 2022 R1

From the Create Calibration dialog, choose

Enter a scale factor and base point (can use project location)

TPC displays the Calibration From  Scale & Base Point dialog.

Enter a Scale and Base Point Manually

Choose Get Scale  & Base From Project

Choose Save as Calibration.

TPC displays the Calibration Properties, allowing you to check the calibration parameters and document what the calibration is, like it does for any new calibration.

When you are finished documenting the calibration, save it.

You can now use that calibration file.

Distance Suffix

Distance suffixes used to be hardwired in.  Now, just include the space in the style if you want it.  You’ll get 14.56′ vs 14.56 ‘  or 14.56ft vs 14.56 ft.

Coordinates or Geodetic Positions

Legal descriptions can now include coordinates and/or geodetic positions for calls.  TPC users have asked for this feature in order to further integrate their GPS/GNSS surveys into all their workflows.

Plus, we added the new style files Coordinates.xml and Geodetics.xml to your Program Data folder so you can get started right away.


This nested phrase further describes the point of commencement, point of beginning, either the beginning or end of the course being described, depending on which phrase it is nested in.

Available Place Holders


Typical Phrase

, at or about <GEODETIC POSITION>


Commencing at a Point of Commencement<SAID POINT BEING><HAVING GEODETIC POSITION>; Thence <LINE DIRECTION>, a distance of <LINE LENGTH> 

Here, TPC brings in the Latitude and Longitude of the Point of Commencement, which is the beginning of the course being described.

Example Usage in <SPIRAL TO TANGENT ARC>

to the beginning of a curve<HAVING GEODETIC POSITION>, tangent to said spiral<BEGINNING OF SAID CURVE BEING>; Thence <ARC COMBINED DIRECTION> a distance of <ARC LENGTH> along the curve concave to the <ARC CONCAVE DIRECTION>, having a radius of <ARC RADIUS> and a central angle of <ARC CENTRAL ANGLE>

Here, TPC brings in the latitude and longitude of the beginning of the curve being described.

You can now specify a starting number for drawing tables.

New: Use Equations for All Factor Fields

We added more options to send objects from a Drawing View to a CAD View.  You can now select an object and send all the objects on that layer.

New: Convert to Survey Elevation Option

You now have more control over how TPC uses elevations when comparing new survey points to existing survey points.  It’s a little thing that can make all the difference when you need it.
