Many thanks gentlemen.
I found an earlyer thread with some usefull info: Placing a logo onto a surface
I will go over that and add the information that you gave me here, much appreciated.
I indeed missed the ‘‘solid option’’ that would solve a lot already 
Yes filleting is going to be some work i guess, anyway slowly i’m getting a little bit ‘‘the hang’’ of Rhino.
Kind regards, Robert Glotzbach
