Geometrical product specification (GPS) and model-based definition (MBD) (2 cr)

Evaluation scale

Pass/Fail

Objective

The student is able to model the items to be worked on and produce drawings of them containing advanced geometrical product specifications and dimension items as 2D drawings and directly into 3D models based on model-based definitions. The student is able to adjust the settings of 2D drawings and model-based definitions to correspond with current standards.


EA-EE: EUR-ACE Engineering design / TKNSU: Competence in design:
The student is able to model the items of their choice in 3D and understands the possibilities of model-based definitions. The student is able to prepare unambiguous 2D images based on mechanical drawing standards.

YHTVI: Communication skills: Students are able to attach drawings and technical documents to their assignments and theses. The student knows how to use the 3D PDF data transfer format.

Content
