This tool has no parameters. It acts on the layer selected in the Contents pane, and on the current feature selection.

ទិដ្ឋភាពទូទៅ

These graphics are temporary. They are map overlays, not labels. They are not saved with the project and they disappear as soon as the layer selection changes, the active map view changes, or the active tool changes. For labelling that persists and prints, use Bearing Distance Calc, which writes the values into a permanent table and line layer.

ការប្រើប្រាស់

  • Clicking the button draws the overlay immediately. There is no dialog.
  • Exactly one line layer must be selected in the Contents pane. If nothing suitable is selected the button is disabled, and clicking it with the wrong selection reports "Select a line feature layer."
  • The layer must use a projected coordinate system. Bearings computed in a geographic coordinate system are not survey quantities.
  • The current feature selection is honoured. If features are selected in the map, only those get the overlay; with nothing selected, every feature in the layer is drawn. Select a handful of features first when working on a dense layer, or the display becomes unreadable.
  • Overlays clear automatically when you change layer selection, switch map view, or pick a different tool. Run the tool again to redraw them.
  • Line direction determines the bearing reported. A line digitised in the opposite direction shows a bearing 180° away from the expected value — if a bearing reads back to front, flip the line rather than doubting the tool.

របៀបប្រើ

  1. In the Contents pane, select the single line layer you want to inspect.
  2. Optionally select a few features in the map, to limit the overlay to those.
  3. On the KGA Toolbox tab, in the Data Management group, open the Quick Label menu and click Display Line Bearing and Direction.
  4. Read the values on the map. They clear when you change selection, map, or tool.
