The Alignments menu commands make it easier to process horizontal alignments defined by unique points and obtained from files generated by other programs or from polylines in a drawing.
Horizontal alignments are composed of vertices (unique points), which have the following information: station, X coordinate, Y coordinate, azimuth, radius, parameter and length.
The polyline with which the program represents a horizontal alignment can be moved, deleted and/or rotated as a whole with CAD tools. Nevertheless, other commands such as cut, extend, stretch, scale or modify vertex coordinates with regard to the others should not be used with them. These operations lead the program into showing a warning indicating that there are inconsistencies among the polyline’s vertices and the alignment’s vertices when a drawing’s polyline is selected. Although the command continues to work after the warning, one has to check closely if the alignment information corresponds with what has been drawn.
