PLACING DIMENSIONS ON
AN ISOMETRIC DRAWING
The purpose of an isometric pipe layout is best
served by a simplified dimensioning system. Because
few dimensions are shown, draw accurately to scale, so
the layout can be measured.
Practice dimensioning by redrawing the pipe
diagram of figure 1-13 as an isometric pipe layout.
Ensure the lengths are to scale, and dimension the pipe
size accordingly. Also, make a list of fittings and pipe
So far, the principles of reading prints and drawing
sketches have been discussed. To practice these rules,
look at the three isometric drawings in figure 1-14 and
sketch three, 3-view drawings, properly dimensioned
