Very useful application for technical school students and engineers. Learn or test your skills in the orthographic (orthogonal) projection through interactive way on your smartphone or tablet. This application will show you that learning can be very fun! Your knowledge will be appreciated in this application with the stars.

Application features:

--- No advertisements and no in-app purchases
--- Application improves spatial orientation
--- 1st Angle Projection
--- 3rd Angle Projection
--- Easy mode (rotate, mirror)
--- Hard mode (rotate, mirror and mix)
--- 32 parts (more soon)
--- Interactive 3D model of the part
--- Symbolic drawing creation of each part at the end

These knowledges create basics for cad modelling, design and drawing of sketches, sheets, papers or notes in engineering.

Many successes !
