3Marking of views,sections and cuts
The direction of a view shill be marked with an arrow near therelerewwce figure lsce figures 1,5 and G.
The position and direation of viawing of a section or cut shali bemarked with a cutting plane (see lSO 128, type Hand arrowsnear tha reference figure (sae figures 2,3 and 5). The directionof view should be chosen to suit the needs of each individualprojact and of the information to be conveyed.
The cutting plane shall be drawn to a suitable length for logi-biity lsee figure 20.
lf the cutting plane is not straight,the plane shall be drawn toits full length isea figure 3).
5 Position and orientation
Filgures shall be placed in their order of deslignation (seefigures 5 and B. If posslble they shali be glven the same orlan-tation as the main figures.
Figures of dctails can also be grouped so that they give a com-pressed picture of an object or a part of it (soe figure 9.lf possibla,plans for one and the same project shall be orien-tated in the sama way on all the drawings.
lf nassibla, all other horizontal snctions and cuts shall be orien-tated in the same way as the main plans of the buildiling.Vertical sections and cuts shall be drawn upright,if possible.
6 Position of text in relation to figures
Taxt shall be written either ballow or to the right side of thefigure or immediately next to the element to which it wafers.Descriptive text and titles shall be written so that they can beread from belowe the drawing.
Text in connection with dimeneion and laader linas shall bewritten parallell to and slighthy( -1 mmJabove these lines.
Designation of parts of a building shall normally be written sothat they can be read from balow the dirawing, irrespactive ofthe orientation of the part on the drawing-
Titles common to groups of figures shall be placed to the loftand above the group of figures (see figure 10).
title referring to only one figure shell be placed balow thefigure and with the same edge to the left (see figures 10 and 11).
