This utility will allow us to automatically calculate the 2D and 3D length of all the selected polylines.
Once the polylines have been selected, the program will show us a list with this information in addition to other parameters such as the initial and final coordinates and the area of the polyline.
Finally, we will have the possibility to label in the drawing, in the initial vertex of each polyline, the 2D and 3D length of each of them.
