Summary
This subject is fundamental one to subjects that deal with standards and technical product documentation. Students will acquire basic knowledge of standardization, production and reading of technical drawings, imagery, dimensioning, tolerances of machine parts and record in title blocks, signification of surface quality, signification of glued, soldered and welded joints. The emphasis is placed on self-reliant creative technical thought during individual school assignment on tutorial.The aim of this subject isa formation of skilled student character to be able to use basic knowledge in next technical subjects and technical profession in drawing-office, design-office or in manufacturing.
