Dual coordinates

This dialog window serves to work with dual coordinates on the lists.

You have to enter the basic coordinate file in the section Files and the additional file for some functions. The files are selected by mouse dragging to the pertinent box or by pressing the button (...).

Import from additional file

This function serves to complete the second coordinate pair from the additional file. After launching the function, the program attempts to find the coordinates to all the points of the basic file in the additional file. If it found them, they are completed as the second pair in the basic file.

Replace main and secondary coordinates

After pressing this button, the program replaces the main and the secondary coordinates on the main coordinate list. If you want to use the secondary coordinates instead of the main coordinates, you have to first replace them using this command.

Export secondary coordinates into new file

After pressing this button, the program creates a new unnamed coordinate list and copies all the secondary coordinates from the basic list into it. The coordinates are saved as the main ones on this newly created list.

Remove secondary coordinates

After pressing this button, the program removes all the secondary coordinates from the basic coordinate list.

Remove zero secondary coordinates

After pressing this button, the program removes the secondary coordinates from the basic coordinate list if both of the secondary coordinates are zero.
