I did "Calculate Geometry" on a line shapefile to obtain the coordinates X and Y for the start and the end of all the lines of the shape. But some lines resulted with the same X on the start and on the end, and the same Y on the start and on the end.
If the line is crossed by other line, the X and Y that results is the X and Y of the point where the line is crossed. So X,Y are the same because it's a point. My question now is why Calculate Geometry does that?
This is one of the affected lines:
Thsi is another line and its properties
