ENGN103 ENGINEERING DRAWING
ISOMETRIC PROJECTIONS
LECTURE 4
WHAT IS ISOMETRIC DRAWING?
It is a method of producing pictorial
view of an object showing all three
faces of the object simultaneously.
It is a type of parallel projection.
It is a type of axonometric
projection.
ISOMETRIC PROJECTIONS
Observer is placed at infinity.
Projectors parallel to each other and perpendicular to
projection plane.
Object is inclined with respect to projection plane in order
to see all the three faces.
ISOMETRIC TERMINOLOGY
1. The three coordinate axes are
called isometric axes.
2. Any line parallel to isometric
axes is called isometric line.
3. A non-isometric line is a line not
parallel to any of the three
isometric axis.
4. In isometric projection of cube,
the faces of the cube and any
plane parallel to them is called
isometric planes.
