Hello Michael!

@You "...Did you mean you wanted him to show a model covered with dense isocurves in it?..."

Ho no...certainly not :) I only wanted to ask Fabrizio to show us the topology of only some of the "key" area of its wonderful car.
Just in order, as you said, to figure out how he built the surfaces.

And the "multiiso+" command can be one the easy way to do that without going out of Moi.

Thanks.
