Use the elements in the dialog box to modify the parameters of an orthogonal projection.
- Element
-
Base line for orthogonal projection: P1 – P2
Click Graphic icon
to identify another base line. Type an Offset value or use the Graphic icon
to shift the line. Type a Radius value, if your base line is an arc.
Type an Azimuth value or use the Graphic icon
to modify the orientation of the base line. - Point 1/ Point 2
-
P1: If the base element is an arc (radius is not null), you can use the Reverse icon to switch between long and short arc.
- Easting/ Northing/Elevation
-
You can edit the coordinates in the dialog box or use the Graphic icon
to select another point. - Point P
-
P: Point to be projected. Use the Graphic icon
to select another point. - Projection
-
Coordinates of the projected point on the line.
- Distance Measured/Calculated
-
Length of the base element, distance between P1 and P2. You can enter a measured value to calculate a factor for adjusting the resulting abscissa.
- Abscissa
-
Abscissa value of the projection line (ordinate = 0,00).
- Abscissa P1
-
