Inroduction
This process covers the art of drafting. Many element for structure
steel detailer for practice discussed Here. Initially D05 Design and
Engineering want drafting equipment, and so many techniques are
required for the practical work of different kinds of work, like
lettering, dimensions, symbols, line thickness, breaking lines,
provision of match lines, scaling details, indication of bolts and bolt
lines, indication of welding, orthographic projections, elevation and
section arrows and finally abbreviations.

Equipment
In all the workshops detailed drawings are made on plastic
drafting film or tracing paper with pencils. For this drawing we
take a print or a dye-line print sometimes, drawings prepared by
ink on drafting film, so that it can b there for a long time. In
structural steelwork, detailer equipment requires as follows
(a)drawing board, furnished with a separate T-square,
(b)drawing paper or film
(c)pencils
(d )pencil sharpener
(e) pens, supplied in point diameters (F) protractor

(f)compasses
(g)circle template
(h)eraser and shield
(l)french curves
(j) calculator —the Necessary aid in the summing of dimensions
is a scientific electronic calculator, for calculate the bevel
dimensions & bracing end clearances, and the calculation of
steelwork masses on quantity lists.
computer-aided drawing (CAD) programs
(k) computers — So many fabricators are using various
to assist in the
preparation of 18 layout and detail drawings. This is aspecialized
technique, but results in significant time savings on larger
contracts

Lettering and dimensions
There is No particular way recommended for lettering but for
decent copy prints a number of practices have indicated. For
drawing titles stencils we always used them for view. A number
of different lettering schemes and symbols are produced by
computer-aided machines. every time The main quality requires
the clarity and uniformity of all symbols. The minimum size of
the lettering in the UK and the USA is 2·5 mm and 3 mm
respectively. All notes, letters, dimensions, and arrowheads
used on plans, elevations, sketches, and erection drawings are
either computer generated or free drawing . For storage
purposes,
5.
sometimes the drawing should be microfilmed. and after that
when it is printed then the size of the drawing will do enlarged
so that print can be taken. sometimes when the drawing is
enlarged the scale of the original size is lost. for this reason D05
Design and Engineering | One-Stop-Shop provides on the
original drawing a scale at a bottom edge. in this arrowheads
are should be sharply pointed and touchable on line Dimension
lines
should be dark, thin but unbroken lines.
