In order to describe a spatial body adequately and thereby fulfil a basic principle of exact replication and repeatable production, several views of the body are usually necessary. To do this, bodies are shown in three planes: front view, side view and plan or bottom view.
The presentation follows fixed rules that are defined in the standards. Even for simple bodies, the presentation in three planes requires a considerable degree of abstraction ability and spatial imagination on the part of students. This ability is a prerequisite for both creating and interpreting engineering drawings or sketches and is taught by means of geometric models.
The GUNT DigiSkills 1 learning project includes various model sets, from the simple geometric model to models with real function. The TZ 100 model set provides a learning concept for the introduction to the field of “Descriptive geometry”.
A room corner for the multiview projection, which is composed of three surfaces, holds the models. The corresponding view is inserted in each surface of the room corner so that direct comparison between the model (workpiece) and the drawing is possible.
A total of ten models of varying difficulty are included. One model is made of acrylic in order to develop an understanding of hidden edges. The other models are made of aluminium.
The models are precision-manufactured so that measuring exercises can also be conducted. All parts are clearly laid out in a storage system. Multiple storage systems can be stacked on top of each other for space-saving storage.
The contemporary didactic multimedia instructional materials are available online in the GUNT Media Center. The core element is a complete set of drawings in file form (DXF, STEP, PDF) for each model. A selection of different worksheets with solutions completes the instructional material.
