What are the different views of the profession

Technical draftsman (apprenticeship) - apprenticeship period: 3 1/2 years

"I've always been interested in technology, even as a child I loved playing with Matador. Spatial thinking is one of my strengths and so I decided to become a technical draftsman."
DIin(FH) Margit Malatschnig, technical draftsman and industrial engineer, Techkonnex - High-Tech Promotion, FEMtech expert, October 2007

The creation of technical plans and documentation is one of the main tasks of draftsmen. They manufacture these according to the specifications of engineers, technicians and designers, taking into account the legally prescribed standards and guidelines. Depending on the specialist area of ​​the company for which the draftsman work, different technical documentation is required. Examples are:

Machine and apparatus construction:
Construction drawings, process flow diagrams, work drawings of molds, metal articles, boilers etc. as well as detailed and installation drawings of components, motors and machines, but also for automated series production (CAM = Computer Aided Manufacturing)

Electrical engineering, communications engineering:
Schemes, installation drawings, circuit and distribution plans, views of high, medium and low voltage or extra-low voltage switchgear, energy balances, flow charts, technical reports and quantity take-offs.

Installation technology:
Line, duct, pipe and control circuit diagrams for heating, sanitary or air conditioning systems, sections and isometrics, ventilation, cooling and water calculations, technical reports and quantity take-offs.

Depending on the order, technical draftsmen work with different types of representation. You put z. B. show the product in the assembled state and then make detailed drawings that provide you with all the information necessary for production. This includes, for example, dimensions and tolerance specifications for the individual components. You determine technical values ​​such as lengths, angles, volumes and areas through dimensions either mathematically or take these values ​​from tables. Workpieces with cavities (e.g. bores) are shown in section. Hollow bodies made of sheet metal are "unwound", i. H. they record the surface of the hollow workpiece. They represent penetrations of a basic body through auxiliary planes or auxiliary cuts.
