Isometric Drawing Part 1

Isometric Projection

Isometric projection is a 3Ddrawing using the 30-60 degree angle set square.

All Isometric drawings start with three basic lines forming the corner of a “box” that contains the object you are drawing.

It is very important that the 30-60 degree set square is placed on the parallel motion/sliding ruler when drawing your angled lines.

At all times the drawing equipment is there to assist in drawing shapes and objects without too much measuring or calculating.

Use A3 Paper1cm border, 1cm name bar, 2cm indent.

Remember to use a 30 degree Angle set square placed on the sliding ruler for all the angled lines

Use 30 degree angles to join up the roof

80mm

Measure 10mm gaps along the ridge on the roof

10mm

Use 30 degree setsquare

Mark off 5mm spaces on the base sides of the roof

Place your set square at the 60 DEGREE angle to draw in the tiles

Repeat on the right side of the roof
