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 required (MTO).
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 dimensionedContinue Reading
