Line by Parallel OffsetLine by Parallel Offset

Availability: Computations module.
Menu Selection: From the Computations task, select the Create/Line command and the Method/Parallel command.
Functionality: associated points
Controls:
Actions:
  • The OK Button creates the line and the new points.
  • Next
Notes:
  • The Elevation Drop Down will only be available if the elevation attribute is active.
  • The offset (i.e. distance) which is measured in a perpendicular direction from the existing line to the new line and points being created.
  • A negative offset will be applied to the left of the existing line, whereas a positive offset will be applied to the right, according to the general direction defined by the Line Identifier
  • The angular geometry of the new line will be identical to the line on which the operation was based. If the line on which the operation was based contained bends, then the distances along the new line will not be the same as those along the existing line.
  • The points created will be given the attributes of the currently defined point attribute .
  • The new line created will be given the attributes currently defined line attribute.
  • The identifier in the new point identifier control will be used for the first new point and any subsequent new points will automatically use the next unused point identifier.
  • If the system is in other than grid distances, the offset used will be the grid offset computed at the first point of the existing line.
  • If the selected line is a spiral, the resulting parallel line will be a spline.
