I updated the dropbox link with the possibility of the object to edit the Profile which follows the path direct in 3D.
Also i added a new part which makes the same with 3 editable profiles also editable direct in 3d and a new parameter -z-offset to move the profile in 3D-Z, so that the path is better adjustable. After editing the path - set this z-offset to 0.

I work on a change of the additional points around the path-corners which are currently generated aut of the with of the first profile. There shall be e fixed parameter instead.
Then - it would be possible to simple copy the part to make additional profiles following the same path.
