Hello DennisA and Tech,
Dannis solution converting the object to faccetted worked but I think i should not be the proper way to work the model for further modelling.
Tech's solution with the imprint tool doesn't work. When you execute the imprint tool the segment dissapears.
I would be nice if the offset of a curved face goes along the curve itself....I think is not possible right now.
Thanks for the takinf into account the corretion.
