Isometric drawing is a quick and easy way to draw accurate design drawings
in this video I'm going to introduce you to the basics of isometric drawing
Welcome back to Art Bites my name is Mr Heaton isometric drawing is a type of 3D drawing that
is especially suited for design it can be used to draw precise functional drawings to explain
how something works or how something is put together or it can be done freehand for quick
accurate sketches that allow the designer to get their ideas down onto paper really rapidly
these freehand drawings are often accurate enough for a designer to show to clients in the early
stages of a design to work out if the design is developing the way the client wants it to
everything in isometric drawing comes in multiples of three
so in isometric drawing we have three directions of line we have vertical and we have two different
diagonals and those diagonals are the same all the way through the drawing
those diagonals are at 30° another multiple of three from a horizontal line
or at 60° when they're close together or 120° when they're a bit further apart
so that's everything is in these multiples of three so if you wanted to be really accurate with
your drawing you could get out a protractor and you could measure each of these angles perfectly
or you could get yourself one of these those random triangles for your math sets
it's called a set square and that will give you your 30° angles or your 90° angles really really
easily if like me however you're using isometric drawing just to sketch out some ideas you can do
this by eye as well the easiest way I find to do this is to start off with a letter Y
because that shape gives me all of these lines and it's quite easy to do by eye
because you can very quickly tell if it's off because these angles will look quite different
from each other so as long as these angles look roughly the same you've got it roughly accurate
now isometric drawing or isometric projection is now used in a variety of other settings from
exploded drawings in flat pack furniture instructions to mobile game design because
isometric drawings always look like they're being viewed from that one corner one of the benefits is
that unlike perspective drawing the final image isn't distorted in any way by the distances
in fact the word isometric comes from greek to mean equal measure
so let's draw our starter cuboid so I'm going to finish this off by adding two matching diagonal
lines they just need to match the ones from those that starting y shape and I'm going to
overshoot them slightly because then I don't need to worry about the length I can just focus on the
angle and I can rub out the bits I don't need so I'm then adding two matching vertical lines
and I'll finish up with
some matching diagonal lines again notice how these are parallel all the way through the drawing
if you wanted to make this drawing see through I would then add lines on the inside so I could
start at this corner and again keeping it parallel and again I'll try and overshoot
because that makes my life easier oh look at that perfect by adding these internal lines
it's helpful when you want to add other sections to your drawing so for example
if I wanted to add another cuboid coming off this direction and I wanted to make it look
like it was attached to this one I could do that by drawing it on that side and then carrying it on
remember if you've drawn your lines lightly you can
easily rub out the bits you don't need at the end
