Abstract
In French secondary level schools, spatial geometry teaching is an important goal in mathematics teaching, an a difficult one, mainly because of intrinsic difficulties of this part of geometry. Indeed, students are often unable to see and understand the display of a 3D figure on a 2D device, and then to proceed an efficient abstraction of it. Moreover, the 'wire-frame' geometry does not introduce the same difficulties as the solid geometry : in particular, the translucent aspect of objects does not ease their relative perception. Thereby, the use of computers to display real-time and interactive images of 3D construction should be helpful for overcoming this drawback and naturally led us to explore the field of Dynamic Geometry. Calques 3D is an educational software for the construction and the observation of geometrical figures in space that intend to reduce these difficulties. It allows an intuitive and adaptable access to environment functionalities. Intuitive because it has to be used by students without a long-time initiation. Adaptable because it allows the teacher to decide, with respect to his own pedagogy, which primitives and functionalities would be available for the student.
