Abstract:

Engineering Graphics is an important technical basic course known as the language of  engineering  and  technology  (design  language)  ‘in  two  dialects’:  the  First-angle  orthogonal projection  (earlier  referred  to  as  method  E)  and  the  Third-angle  orthogonal  projection  (earlier referred  to  as  method  A).  This  course  for  engineering  students  is  essential  for  introducing engineering  to  their  further  studies  and  it  involves  several  disciplines  (e.g.  Machine  Design, Engineering Measurements, Mechanical Engineering Projects). Engineering Graphics serves to create  a  graphic  model  (engineering  drawing)  according  to  which  machine  parts  can  be manufactured  and  machines  and  buildings  can  be  assembled.  Graphic  models  can  also  be considered in the aspect of semiotic principles. The tools of expression of Engineering Graphics are graphic representation, figure (image) and drawing specification, which are perceived by the visual and auditory organs (in the case of verbal contact between the writer of a drawing and the reader of a drawing, i. e. oral form), and represent the means of communication for engineering practice. The requisite elements  for communication are: sender (writer of a drawing), receiver (reader  of  a  drawing),  channel,  medium  and  at  least  a  partially  overlapping  sign  repertoire  of sender and receiver. In order for overlapping to be complete and unambiguous, the Engineering Graphics  course  begins  with  learning  the  design  language  which  is  based  on  graphic conventions.
