What’s New in TPC Desktop 2019 R1


We’ve improved more than a dozen workflows TPC users rely on the most.


September 18th 3:00 PM PDT

  • Geoids (7:31)
    1. TPC now computes elevations and ellipsoid heights based on a user selected geoid model.
    2. Seven geoid models are provided, including egm84, egm96, egm2008.
    3. You can also use your own geoid models that are in the .pgm format.
    4. TPC can cache geoid data over the extents of your survey so speed up geoid computations.
  • Surfaces (16:33)
    1. Stakeout Report
    2. Using Surface Tools
    3. Move elevations of existing survey points to a surface. Great for stakeout.
  • Help Topics (33:50)
    1. Added an Elevations landing page to discuss all the ways TPC works with elevations
      1. like geoids, ellipse heights, benchmarks, instrument heights and more.
    2. Added a Surface Elevation landing page to discuss elevation options and tools
      1. like transects, profiles, cut sheets, restricting elevations of contours and more.
  • XReferences (40:58)
    1. XRefs now reproduce the same layers they had in CAD – related to nested block references above.
    2. TPC has improved the handling on long XRef layer names, whether the XRef is bound or unbound.
    3. XRef blocks are no longer stored with drawings in the .TRV file. They are now managed entirely by the XRef.
  • Calibrations (52:00)
    1. You can now calibrate and uncalibrate objects from the Drawing Data Manager – no more hunting them down in the drawing.
    2. The Calibrations node in the Drawing Data Manager is now much more selective and only shows calibrations involving objects in that drawing.
    3. You can now calibrate a CAD file when importing it.
  • Dynamic offsets (1:01:00)
    1. Can now begin/end perpendicular to any point on a circle’s circumference.
  • GIS (1:06:00)
    1. TPC now reads traverse names, point labels and point descriptions when importing it’s own exported GIS files.
    2. TPC now supports geodetic shape extents when exporting GIS files.
    3. Undo/Redo is now available when importing Polyline shapes.
