The geometric models support the learning process by providing an introduction to technical drawings: from the solid model to the more abstract representation of the three views in a technical drawing.
  The TZ 110 set contains 18 aluminium drawing models. The cylindrical models have cut-outs parallel to the main axis of the model. The models are precision-manufactured and are suitable for measurement exercises as well as drawing exercises. 
  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.
  The models are clearly laid out on a tray. Multiple trays are stackable, providing for space-saving storage.
 
  The instructional material includes a complete set of drawings. It includes each model in three views, as well as its 3D view and production drawing.

- familiarisation with three-dimensional views as the
  basis of technical drawing
- step-by-step development of three-dimensional
  visualisation: from the solid model to the more
  abstract views in a technical drawing
- systematic familiarisation with a wide range of
  features on cylindrical base forms
- exercises in production-oriented and standard
  dimensioning
- measurement exercises: outer dimensions, inner
  dimensions, tolerances
