+====Graphic graph of coordinates of vertices of a line in angular coordinates according to the linear XYZ form====
+Strangely, the coordinates of the <track-axis> section do not seem to work on the coordinates given in the form: <x1-m> .. </ x1-m> ... <z2-m> .. </ z2-m >. We must give the coordinates in the form <x> ... </ x> ... <z> .. </ z>. To easily convert vertices, you can use the 3D CAD application FreeCad. You create a line by inserting the two vertices (V1 and V2) and then activating the Bounding Box display, as shown in the figure. The 3 coordinates X, Y, Z can be used directly as X, Y, Z coordinates. But be careful with the signs.
