Exercise 5.6
Draw the isometric view of the machined block having non-isometric lines. (Fig 6a)
• Draw an isometric box. (Fig 6b)
• 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.
• Mark point D on US such that UD = 20 mm.
• Draw a line DC parallel to UT equal to AB.
• 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.
