@spikeyxxx , Wauw, great. Thanks for the (indeed detailed) instructions. It is quite a procedure. Just to make sure that I get it:
what you are doing is replacing the geometry of the individual lines with the (linked) geometry of our model. Right? That is the basics. The origin is because we created the individual edges by splitting the iso sphere, which leaves the origin of each edge at the same position of the original sphere. I see that indeed snap origing to geometry only works on the position and leaves the orientation. And the entire procedure is to align that origin easily using the snapping. That is indeed a nice move, albeit tedious. Thanks!
And I did not know about the V shortcut.
