Sketcher reference/fr

Introduction

L'utilisateur chrisb a rédigé un long manuel de référence de 70 pages pour l'Atelier Sketcher qui couvre de nombreux sujets relatifs à l'utilisation de ce workbench. Pour les utilisateurs inexpérimentés, il s'agit d'une introduction qui couvre l'utilisation de base de Sketcher puis aborde de nombreux détails concernant la création d'éléments géométriques et l'utilisation de chaque type de contrainte.

Le manuel est un travail en cours. Certaines sections sont revues et mises à jour en fonction du développement survenu dans l'Atelier Sketcher. Le manuel original a été écrit pour FreeCAD 0.17 et a depuis été mis à jour pour la version 0.18. Le manuel le plus récent se trouve dans le fil de discussion du forum, Didacticiel Sketcher.
