Cool ! I was affraid that I miss something...

Yes the classic Orient tool is very good and quicker but a little intimidating with
the 4 different combinaisons of cases to check or not!
And the rotation of the axes themselves is a little tricky! ;)

For my part Line-line seems to me more funny (if possible) and can Scale in the same time!
And the use of the Helper Lines add to the pleasure to use it! :)

And I love to use functions for other things that they are made for! ;)
