Thanks, seems to do exactly what I want... except it is not implemented for co-dim = 1 (by the way, I do not see where the dimensions are relevant for this process).

We'd gladly see a patch that fixes this :-)

The challenge is that in the codim>0 case, a point isn't unambiguously going to lie in a cell: You need to extend the pull-back to points that aren't on the manifold, and then project back onto the dim-dimensional reference manifold. I don't think this is *particularly* difficult, but it needs to be done.
