For these exercises, you will need to use a SKETCH EASi Stencil. The dxf file can be downloaded from http://www.technologystudent.com/despro_flsh/sketch_easi1.html. Use a laser cutter to
manufacture the stencil (blue lines - etch AND red lines - cut through).

USING THE ISOMETRIC GUIDES AND A FINE PENCIL,
DRAW THE FIRST ‘CORNER’ OF THE
CUBE.
CHECK THAT THE LENGTH OF EACH LINE IS THE SAME MEASUREMENT,
FOR EXAMPLE 40mm.

MOVE THE STENCIL TO THE TOP OF THE VERTICAL LINE YOU
HAVE DRAWN.
THEN DRAW THE TWO TOP LINES WITH THE ISOMETRIC GUIDES
CHECK THAT THESE LINES ARE THE SAME LENGTH, AS ALL THE
OTHER LINES.

TURN THE STENCIL ROUND TO 90
DEGREES AND DRAW THE TWO SIDE LINES.
THE ISOMETRIC GUIDES CAN BE USED
TO DRAW THESE LINES AS WELL, IF YOU WANT TO TRY
THIS OUT.

USING THE SKETCH EASi STENCIL, DRAW
THE CUBOID, FOLLOWING THE SAME STAGES AS
FOR THE PREVIOUS EXERCISE.
REMEMBER, THE SIDES ARE NOT ALL
THE SAME SIZE, THIS WHY THIS TYPE OF SHAPE IS CALLED A
‘CUBOID’.
