Le dessinateur app for iPhone and iPad

This is to reproduce a model symmetry or three-dimensional.

It is used to develop or restore mental representations and organize benchmarks to plot surfaces and volumes.

Easy level: one must define a graphical plot with respect to a horizontal axis of symmetry, vertical or oblique; one side is drawn and shall be printed on the blank side.

Middle level: an incomplete route is proposed dispatched on both sides of the axis of symmetry, the patient should reform the complete figure by tracing the missing features.

Difficult level: we propose a two-dimensional form and edges that leave each vertex, connect these points to obtain a three-dimensional figure.
