Basic Terms - Horizontal Geometry Elements
For onboard input Roadworks 3D supports the
following elements for horizontal alignments:
1. Straight
A straight has to be defined by:
•
Start point (P1) and end point (P2) with known
easting and northing coordinates

easting and northing coordinates
•
Radius (R)
•
Direction: Clockwise (CW) or Anticlockwise
(ACW)
