Orthogonal Projection Elements

Element	Description
Element	Base line for orthogonal projection: P1 – P2 Click to identify another base line. Enter an Offset value or use to shift the line. Enter a Radius value if your base line is an arc. Enter an Azimuth value or use to modify the orientation of the base line.
Point 1	If the base element is an arc (radius is not null), use to switch between a long and short arc.
Point 2	P2
Easting Northing Elevation	Edit the coordinates in the dialog box or use to select another point.
Point P	P: Point to be projected. Use to select another point.
Projection	Coordinates of the projected point on the line.
Distance Measured Calculated	Length of the base element (the distance between P1 and P2). Enter a measured value to calculate a factor for adjusting the resulting abscissa.
Abscissa	The abscissa value of the projection line (ordinate = 0,00).
Abscissa P1	See Also Cogo: Orthogonal Calculation
