Create by Bearing and Distance

Description

Compute a vertex by bearing and distance.

Access

Home / Tools / Create / Point / Bearing and Distance
Home / Tools / Create / Line or Alignment or Polygon / Straight or Spline / Bearing and Distance

Requirements
  • Solve module
  • Profile module (Alignments)
Controls

The following controls are available:

Control Description
Name Type the name to assign to the created object or click Next auto incremented name to use the next available auto incremented name.
Mode Select one of the following:
  • Radiation - Create a vertex by bearing and distance from the From point.
  • Traverse - Create a vertex by bearing and distance from the previously created vertex.
From The vertex from which the bearing and distance is measured.
Note:
  • For traverse mode, if a line, alignment or polygon is in the process of being created, the objects last vertex is used.
Bearing Input the bearing from the From vertex.
Note:
Distance Select one of the following methods to input the distance from the From vertex.
  • Grid Distance - Input a distance corrected for slope, sea level, geoid separation and scale factor.
  • Ellipsoid Distance - Input a distance corrected for slope, sea level, geoid separation.
  • Ground Distance - Input a distance corrected for slope only.
  • Local Plane Distance - Input a distance that has a local scale factor applied.
  • Slope Distance - Input a slope distance.
Note:
Height Method Select one of the following methods to input a height for the vertex:
From vertex as origin When creating lines do one of the following:
  • Select the checkbox to create single segmented radial lines from the From vertex.
  • Clear the checkbox to compute vertices from the from point, but construct lines from the previous vertex in the line. If a line is not already under construction the computed vertex becomes the first vertex in the line.
Note:
  • Available when creating lines in Radiation mode.
Notes
  • A negative distances applies the bearing in the reverse direction.
  • If a plane coordinate system is selected for the project some of the direction and distance options will not be available.
  • When creating a polygon the From vertex is the first vertex in the polygon.
  • When creating alignments, in the Create Options, configure the Alignment Velocity and the Horizontal Standard to automatically create curves and combined curves at intersection points that comply with the design parameters.
Possible Errors
Error Description
The computation has no solution A solution can not be found that satisfies all requirements. Ensure the height method selected enables a valid solution to be computed.
