Read about CAD (computer-aided design) Before the development of computer-aided design (CAD), prototype design was a time-consuming process characterised by trial and error. Today, 3D drawings make the project real before the first brick has been laid. Apart from the dimensions of the building, more detailed informa- tion are entered into the program. Having defined all parts of the building, the layout or construction of a building can be pictured as two-dimensional floor plans or in a three-dimensional form. The actual measurements are shown on the plan as single dimensioning or dimensioning chains, thereby defining the strength of a wall, the position of a door or the dimensions of a room. Find the translation of the words in the above text: Abmessung: dimension/measurement Einzelbemaßung: single dimensioning Naturmaß: actual measurement Kettenbemaßung: dimensioning chain When drawing a plan, many symbols are needed. Peter is from Canada and doesn’t know the symbols according to the ÖNORM regulations in Austria. Label the symbols below in English with the terms from the box to help Peter understand their meaning. electrical socket cleaning shaft radiator finished floor level in section ceiling light  chimney / flue switch single door handled to the right washing machine Einflügelige, rechte Tür Rauchfang Putzschacht 80 200 single door handled to the right chimney / flue 2 % cleaning shaft Deckenleuchte Heizkörper Schalter ceiling light radiator switch Fußbodenoberkante im Schnitt Waschmaschine Steckdose +12,10 finished floor level in section washing machine electrical socket Mosaic If a plan is drawn to the scale of a) 1:50, b) 1:20, c) 1:100, it means that: 2 mm (measurement on the plan) are a)  10  , b)  4  , c)  20  cm in reality. (actual measure­ ment) Solution: a) 2 mm x 50 = 100 mm = 10 cm, b) 2 mm x 20 = 40 mm = 4 cm, c) 2 mm x 100 = 200 mm = 20 cm 03 A2–B1 04 A2–B1 87 Drawing and scales 20 Nur zu Prüfzwecken – Eigentum des Verlags öbv
