 TZ 140 Prismatic Work Samples with Slanted Cut-Outs
 Technical Description
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 140 set contains 18 aluminium drawing models. The prismatic models have cut-outs parallel to, and at an angle to, the edges of the prisms. 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 presents each model in three views, as well as its three-dimensional image and production drawing.

Learning Objectives / Experiments

- 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 prismatic base forms
- Exercises in production-oriented and standard

dimensioning
- Measurement exercises: outer dimensions, inner

dimensions, angles, tolerances

 Features
* Collection of geometric models providing an
introduction to technical drawing1
* Systematically graduated degrees of difficulty
