WHAT HAPPENS WHEN PART OF AN
OBJECT IS ON AN ANGLE?

Orthogonal/orthographic drawings are
used because they show the TRUE
SHAPE of objects and their parts, which
can be dimensioned accurately

However, the Front View and Right Side
View on the left DO NOT SHOW THE
TRUE SHAPE OF PART OF THE OBJECT

So what do you do in circumstances like
this?
