Picking COGO From a Drawing

TPC lets you pick COGO points, lines and bearings from the current drawing using the [>] button.

Picking Survey Points

Left click the [>] button then left click a point symbol, point label or a line in the drawing. TPC looks for the referenced survey point and puts it into the dialog.

When you click a survey line, TPC picks the survey point from the end of the line that is closest to where you clicked.

Picking a Direction (Bearing or Azimuth)

Left click the [>] next to a direction field in the dialog then select a survey line from the drawing. The direction that is inserted in the dialog will be from the end of the line nearest your click to the other end. To recall the reverse direction, click near the other end of the line.

Beginning in TPC Desktop 2011, TPC returns a direction type that matches the direction type of the dialog. For example, if the dialog is set to use True Bearings, the direction returned from picking will be a True Bearing.

Picking Lines

Some dialogs include a 'Both [>>]' button. This button allows you to select both a point and a direction from the drawing with a single click. Left click the [>>] button then left click near the end of a line in the drawing. The line end point nearest your click is returned for the point and the direction to the other end of the line is returned for the direction. To recall the other end point and reverse the direction, click near the other end of the line.

Picking Points and Direction form Survey Lines

Left click the [>] button and select a survey line from the drawing. If the dialog you are in differentiates between the ends of a line, TPC tries to bring the line in starting with the end of the line that is closest to the point you clicked.

Any direction associated with this line in the dialog will display from the clicked end to the other end of the line. If you need to reverse the bearing, click near the other end of the line.

Picking Points and Direction form Drawing Lines

When you click a drawing line that does not have survey data associated with it (a line you drew), TPC brings in the coordinates of the end of the line closest to where you clicked and displays 'Picked' for the point label in the dialog. The direction of the line can also be picked and displays the bearing or azimuth of the line.

Picking Distance

Left click the [>] next to a distance field in the dialog then select a line or text from the drawing. If yo select a line, TPC retrieves the line length as the distance. If you select any text, TPC pareses the text into it's equivalent value.

Beginning in TPC Desktop 2011, TPC returns a distance type that matches the distance type of the dialog. For example, if the dialog is set to use Geodetic ground distance at the project elevation, the distance returned from picking will be a Geodetic ground distance at the project elevation.

Picking Elevations

Left click the [>] next to an elevation field in the dialog then select an object or text from the drawing. If you select an object, TPC returns the elevation of that object. If you select any text, TPC pareses the text into it's equivalent value.

Some objects, like point symbols and labels, have obvious elevations. Click a point symbol and TPC returns the elevation of the survey point. Click a polyline and TPC returns the elevation of the closest vertex. Click a contour line and TPC returns the contour elevation. So you may want to experiment some with picking elevations.

Picking a Traverse

Left click the [>] next to a traverse list in the dialog then select any drawing object that was drawn by the traverse you want. The tool tips and status line indicate which traverse drew each object as you position the cursor over it.
