Isometric Perspective
An isometric drawing is a 3D representation of an object, room, building or design on a 2D surface. One of the defining characteristics of an isometric drawing, compared to other types of 3D representation, is that the final image is not distorted. This is due to the fact that the foreshortening of the axes is equal.
The word isometric comes from Greek to mean 'equal measure'. (creativebloq.com)
Notes on Isometric Drawing
All vertical lines are parallel (100% vertical - they do not converge at a point at the bottom or top of the drawing like in 3-point perspective)
Keep parallel lines parallel (they do not converge on the horizon like 2-point perspective)
90 Degree objects will be drawn at 30 degrees parallel to the page's bottom edge (see fig. 2 below)
fig. 1
fig.2
We want to draw in ISOMETRIC (notice the top is a rhombus)
NOT in AXONOMETRIC (notice how the top is a square with 45 degree angles)
