Thanks for your efforts, Monsieur Pilou !

I have to construct a lot of curves so edge by edge will be painful ;-)

If the wire is the problem ; what is the type of object needed for loop selection ?

Or asked in an other way : How should I export an object if I want to make use of edgeloop in Moi ?

I do the modelling in Cinema 4D and want to reconstruct it using curves in MOI.
