Hi Pilou,

> I had thinking of this sort of rotation ;)

I think that's probably not the kind of alignment that JPB is talking about, although hard to say without seeing any actual sketches or illustrations of the original question.

But if you want to do what you show there, just snap the points on to that plane when you initially place the image and you're done, here is an example:



You can also set the cplane as another way to control how the image will be placed when you draw it.
