Currently:
only sweep path is toggled correctly in its visibility, the profile is never shown
the sections are always shown
This PR fixes this inconsistency reported here: https://forum.freecadweb.org/viewtopic.php?f=19&t=63544
This change allows to highlight the spline, auxiliary spine, profile and sections of a pipe.
This gives the user a much better feedback of what external shapes are already used to build the pipe
They worked and are nice feature, but the handling with properties must be worked out better. To avoid any incompatibility due to property changes the functionality is removed now.
