Staircases - Architecture Daily Sketches Video Lecture | Sketching: Enhance your Skills - Art & Craft

hey guys boom are here for architecture
daily sketches and I know it's been a
really long time guys we apologize but
we're back and we have a new video on
sketching stairs in 3d so first I'm
going to show the two types of
staircases that I'll be showing in this
video which is a dogleg staircase which
is a very common type of staircases that
we often see in buildings and a tricky
one the spiral staircase now for both
types of staircases we'll be using the
same technique but it's going to be a
there's a slight tweak to the technique
when it comes to drawing the spiral
staircase because the dog leg is very
planar in nature and spiral staircases
curvacious now there are three rules of
thumb when drawing staircases in sketch
form first you delineate the box that
the staircase would occupy in space and
then you try and identify the planes off
the staircase and just outline it within
the box
just identifying the abstracted simple
form of the staircase in this case this
is a small diagram of the dogleg
staircase and finally at details so just
these three rules of thumb for the
technique identifying the box then
drawing out the planes and adding the
tails so first the dogleg staircase I'll
be drawing this in perspective so I'll
be drawing the horizon line where the
vanishing point is going to be and from
the vanishing point I'm going to pull a
few perspective lines and from there I'm
going to place the box within the
perspective lines that will be my guide
and now I'm trying to identify the
planes of the staircase within the box
it's helpful to use the vanishing point
and the perspective lines as guides for
determining where the points of each of
the planes are see I've identified one
flight and now I'm identifying the other
flight so now we have the basic form off
the staircase and after which we can
start adding details on it like the
tread and risers and also map maybe
adding thickness to the slabs to make it
look a bit more realistic
now there are proper ways to divide the
flight so that you get an even
distribution of steps but for this one
I'm simply eyeballing it and just sort
of roughly putting in the the height of
the risers because this is a simple
sketch
now I'm adding another detail maybe just
some simple railings
and there you have the dogleg staircase
okay so now we're going to try and
attempt the tricky one this spiral
staircase
now it's the same method but there is a
slight tweak to it in that we have to
divide the box that the space of the
staircase occupies into four quadrants
both in plan and also vertically you'll
see in a minute we have to do this
division of the box into quadrants to
take to account the fact that the spiral
staircase is like a series of curved
planes is not a series of straight
planes like in the dogleg so again I'm
pulling the perspective line from the
vanishing point just to roughly
determine where the box of the spiral
staircase is going to occupy
okay so this is where it comes in where
we have to divide the box into four
quadrants both in plan and vertically
you can determine the center of the
spiral staircase by drawing an X from
the edges the center is also going to be
the vertical support of the spiral
staircase and from there you can divide
into the quadrants
it's also helpful to draw out the plan
of the spiral staircase at the bottom of
the box because then we can mark out the
steps in plan and then you can pull the
mark up to sort of extrude the shape
into the 3d and also you have to divide
the box vertically as well into four
quadrants so you see it's in plan
there's four in the plan and then four
vertically as well the reason why you do
this is because when you break it into
four quadrants each of the curves for
each quadrant is easier to determine you
can follow the height and then you can
just sort of roughly eyeball it out so
that you get the outline of the curve
plane it may not be accurate the first
couple of times you try it but trust me
with practice you'll get used to it you
get the hang of it and then it becomes
easier you can imagine from the plan if
you extrude it up it's like a solid
cylinder and when you're marking out the
curve of the plane it's like you're
carving into the cylinder so now you
have the outline of the plane of the
spiral staircase and now you can start
to mark out the steps and the way you do
this is just by pulling up lines
from the plan and see where it
intersects and from that intersected
point you can also pull lines towards
the center and then you can start to see
the form of your spiral staircase coming
to life
so basically it was the same technique
as before we've identified the box and
then we drew out the plane and now we're
just adding up and fleshing out the
details
for the railings you just follow the
same curve of the plane up the spiral
staircase but just extrude it up a
little bit now I'm just adding a human
figure for scale
and for final detailing I'm just going
to ink it out
so there you have it guys
sketch staircases in 3d before I end
