Engineering drawing: three-dimensional display (TZ 100)

Engineering drawing: three-dimensional display (TZ 100)

GUNT course: engineering drawing

Code TZ100


  • 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 TZ 100model set provides a learning concept with which to introduce students to the discipline of descriptive geometry.
  • A 3D frame made of Plexiglas enables Multiview projection.
  • The models are placed in the middle of the 3D frame.
  • The corresponding view is inserted into each plane of the 3D frame, so that it is possible to directly compare model (workpiece) and drawing.
  • A total of ten models of varying difficulty are included.
  • One model is made of Plexiglas 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 and well protected in a storage system.
  • The contemporary multimedia instructional materials are available online in the GUNTMedia Centre.
  • The core element of the teaching materials is a complete set of drawings for each model.
  • The set of drawings consists of DXFfiles, STEP files and PDF
