TZ 100 Engineering drawing: three-dimensional display



  • Model set to develop three-dimensional perception
  • Fundamentals of three-dimensional views


Technical Description

The TZ 100 three-dimensional display is an educational concept for beginners in technical drawing. A three-dimensional stand which consists of three Plexiglas planes has a receptacle for the precision-manufactured models. The associated view can be inserted on each plane of the stand, enabling a direct comparison between the workpiece and the drawing. The student must cut out and fold a template drawing to construct a model.

The model set includes ten shapes, involving differing degrees of difficulty. One shape is made from Plexiglas in order to develop an understanding of invisible edges. The other shapes are made from aluminium. All parts are clearly laid out in a case. 

The model shapes are precision-manufactured, so measuring exercises can also be carried out.

For optimal learning, it is recommended that students work independently from each other on these exercises. Two students can easily work with one model set. Comprehensive and well structured instructional material makes the training system immediately usable in lessons.
