Agile releases, like this one, are all about getting you the tools you’ve requested to help you with your workflows.  You’ll find dozens of additions and changes that will help streamline the things you do everyday.

Adjacent Lots

Lot 1 Adjacent Lots
Lot 1 Adjacent Lots

Many of you want to show the parcel your surveyed in bold, dark strokes for lines, symbols and labels.  But you want the adjacent lots to be shown in a more diminutive way.  Our new Opacity and Traverse Drawing Settings Tabs make this a snap.

In the example shown here, the green arrows show the adjacent lots 2 and 15.

  • We selected just the new Opacity settings for lots 2 and 15, using the new Traverse Drawing Settings tabs  feature.
Opacity And Advanced Tabs Only

  • The opacity settings for lots 2 and 15 are unique to this Lot 1 drawing only.
  • In a few minutes, we created separate drawings, just like this, for all 15 lots in the P.U.D.

Before this agile release, we would have had to open lots 2 and 15 separately and changed the colors of control points, leaders and lot labels separately to get this effect.  Then repeated all those steps for all 15 lots.  Talk about streamlining a common workflow.


You can now set the opacity level of layers, individual drawing objects or using the Traverse Drawing Settings.


Layer Opacity

In the layers dialog, click the Show Layer Settings button to expand the dialog.  Use the Opacity slider to change the opacity of the selected layers in real time.

You’ll find yourself dropping the opacity of these layers all the time

  • TPCFills
  • Background
  • TPCContourMajor
  • TPCContourMinor

These layers are still visible in the drawing, but now take a back seat to the survey information that is most important.

Drawing Objects

Picture Opacity
Picture Opacity

Some drawing objects, like Pictures (raster images), now include Opacity in their Properties dialog.

Set the opacity of individual objects to balance them out with other objects in the drawing.   The opacity of individual objects combines with layer opacity to give you all the control and flexibility you need.

Most of the time, you’ll set the opacity of layers and Traverse Drawing Settings, but when you need a little more control over individual drawing objects, it’s there.

The Picture Settings dialog shown here has its own opacity slider, so when you insert multiple raster images into a drawing, you can use opacity to even them out.

Traverse Drawing Settings

Opacity Tab

Use the Traverse Drawing Settings to initialize the opacity of the drawing objects they create.

TPC provides separate opacity levels for Control Points, Side Shots, Fill, Lot and Location labels.

But you can also use the Entire Traverse slider to override them all.  That’s how we modify the opacity of adjacent lots.

Select Traverse Drawing Settings Tabs

Opacity And Advanced Tabs Only

When you select multiple traverses then choose the Traverse Drawing Settings command, TPC displays the Traverse Drawing Settings Tab Selection dialog.  From this dialog, select the settings you want to update by selecting their tabs.  See Traverse Drawing Settings for Selected Traverses.

For example, if all you want to change the opacity of the lots adjacent to the parcel you surveyed,

  • select those adjacent traverses in the Traverse Manager
  • choose the Traverse Drawing Settings command
  • select just the [x] Opacity  and [x] Advanced tabs and choose OK.

TPC will display just the lot labels dialog and apply the lot label settings you choose to the selected traverses without affecting any of the other Traverse Drawing Settings for those traverses.

Lot Closure Labels

Lot Closure Labels
Lot Closure Labels

Lot labels can now include closure information like Linear Error, Relative Error, etc..   TPC places them just below the area labels, on their own TPCLotClosure layer.  These can also be included in the Lot Table.

You can also format these labels, just like you do point and line labels, to get just the label you want.

Perpendicular Table Labels

Line labels that are manually added to a Line Table, now retain their stacked label orientation in relationship to the line (Perpendicular, Horizontal, etc.) if the [x] Retain orientation of original label

is turned on the Line Table dialog.

COGO Pick Button Requires Existing Survey Point

Some COGO dialog fields require that a survey point be selected.  TPC has tightened up the COGO pick buttons [>] to track with these requirements.  For these fields, if you try to left click a position in the drawing that is not a survey point, TPC displays a warning, saying that only survey points are allowed, and lets you continue to pick a survey point.

Offset to Line Now Has a What List

Multiple Offsets to Line
Multiple Offsets to Line

The COGO, Offset to Line command now has two sections.  One for a single offset to the line and another that uses the What list to generate multiple offsets.  These multiple offsets can be summarized in a report, viewed in a drawing and saved to a traverse.

Contour Labels at Beginning of Contour Only

In a surface’s, Contours dialog, you can now enter 0 for the contour label interval, and TPC will embed one label on each contour, as close to the start of the contour as possible.  TPC still searches for a contour line segment that is long enough to hold the label.

A number of TPC users have asked for this feature to clean up the look of contour labels.  One label, at the beginning or end of each contour line is often enough to identify their elevations.  And yes, it does clean up the look of the contours.

NGS Geoid 2018

TPC now supports NGS Geoid 2018.  You can download and install them from our Geoids page.

We are also set up to move to the new datums from NGS in upcoming releases.

“To improve the National Spatial Reference System (NSRS), NGS will replace the North American Datum of 1983 (NAD 83) and the North American Vertical Datum of 1988 (NAVD 88) with a new geometric reference frame and geopotential datum in 2022.”

“The new reference frames will rely primarily on Global Navigation Satellite Systems (GNSS), such as the Global Positioning System (GPS), as well as on a gravimetric geoid model resulting from our Gravity for the Redefinition of the American Vertical Datum (GRAV-D) Project.”

CAD Improvements

  • New opacity values import/export with CAD opacity
  • Improved TPC imports MText entities from CAD to better handle middle alignments and text box size
  • Solid fills import automatically, without the need to explode geometry & hatching
  • Double precision radii for more precise arcs at very small scales
  • Better import/export of DXF {text\Ptext\Ptext} to improve reuse of existing CAD blocks
