This command allows you to erase a longitudinal drawn by just selecting the polyline corresponding to the longitudinal profile.
The longitudinal terrain will be automatically erased, and all the elements associated with its drawing, that is, elements of numerical data, height, ordinates, vertical alignment(s) ….
If instead of selecting the polyline that represents the longitudinal profile, you select the horizontal alignment, then all the drawings made of profiles created from the selected horizontal alignment will be deleted.
This command will only erase the drawing profile, it will never erase the profile file.
