Engineering Drawing and GD&T Seminar

"αποτυπώνοντας με αποδεκτό τρόπο τις προδιαγραφές"
“defining the required specifications”

Engineering Drawing and GD&T Seminar discusses the basic rules for creating valid, fully dimensioned engineering drawings defined using the appropriate dimensional and geometric tolerances. The basic aim of the teaching material is for the trainee to understand the details that are involved to the creation of fully defined engineering drawings. Attending the Seminar in scope the trainee is to learn how to understand and create engineering drawings that have been created according to the most recent ISO standards.

Engineering Drawing and GD&T Seminar is the perfect training program for the professionals who are involved to the design and manufacturing sectors and seek for the development or the imrovement of their engineering drawing creation or understanding skills.

The Seminar is divided to two distinctive teaching levels that are presented bellow and analysed at the Engineering Drawing and GD&T Guide:
a. Basic Engineering Drawing
(Duration: 32hours)
The first Level of the Seminar aims to the in depth understanding of the basic Engineering Drawing rules and guidelines according to the International Standards (ISO). After successfully attending the first Level of the Seminar, the trainee will be able to understand and create fully defined and dimensioned engineering drawings.
b. Advanced Engineering Drawing and GD&T
(Duration: 24hours)
The second Level of the Seminar aims to the deeper understanding of the advanced topics that are related to the definition of parts and assemblies specifications on engineering drawings. So, Surface Roughness indication and Geometric and Dimensional Tolerancing ( GD&T) are being dicussed and analysed. Material is thoroughly covered and analysed by demonstrating real engineering drawings as examples. It has to be mentioned that the understanding of the teaching material is crucial for everyone who is involved to the design or manufacturing sector.
