Example 3 :
Draw the isometric view of the machined block having non-isometric lines shown
in Figure 3.24.
Figure 3.24 : Isometric machined block
Procedure :
➢ Draw an isometric box and mark point A on PS at a distance of 15 mm from P.
➢ Draw line AB = 25 mm parallel to PQ.
➢ From B, draw a vertical line cutting RS at L and mark point D on US such that
UD = 20 mm.
➢ Draw a line DC parallel to UT equal to AB, then join AD, BC and CL to complete
the required isometric view of the block.
➢ Remove the extra lines and darken the required visible edges.
➢ Show hidden edges by dashed lines.
