How do you spell blueprint in french?

"blueprint" would be spelled in French as "dessin technique / plan détaillé / schéma d'éxécution / plan d'éxécution" if you refer to the technical drawing only. If you want to describe the cyanotype process (http://en.wikipedia.org/wiki/Blueprint), I make the guess that the term blueprint would be used as it seems there is no exact translation. Answer Blueprint= modele But it has a little thing over the 4th letter. Bye x I'm happy to help!
