For the purposes of this document, the terms and definitions given in ISo 10209, IS0 129-1 and thefollowing apply.
Basic requirements of dimensioning are as follows:
a) The indication of dimensions and tolerances shall follow the general principles specified in IS0 129-1.
b) The dimensions of structural metal work shall be simple and clear. The standard plates and profile sections should be represented with code.
C)The datum line of dimensioning should be the centroidal line of component.
To maintain readability of drawings and to simplify drawing, dimension lines can be omitted as shownin Figure 1.
Simplified dimensioning of structural metal work.
Schematic dimensioning of structural metal work shall conform to the representation method specifiedby ISO 5261.
The arc length of a circular structure in the frame should be dimensioned on one side of its line.Anexample is shown in Figure 1.
The representation of profile sections shall use the form of Figure 2; A type code of “C” is requiredto indicate cold formed sections and that the type code can be omitted for all other types of section.”Graphical symbol or letter code”represents the shape of profile sections,see Table 1 to Table 3.The proportion and dimensions of the graphical symbols shall be as specified in Annex A. “Standardnumber” is the code of technical standard which specifies the technical requirements of the section.”Necessary size” is the main size of the section. The parameters of size should be separated with thetimes sign, “x”, see Table 1 to 3.ISO 129 pdf download.
