Hi, this is the third class of our architectonical drawing course I’m going to show you today how to use the skills you
learned in the previous class for drawing a playground for children. Don’t worry about the subject of this task. The important thing is to use cubes to draw an object embedded in human scale. I begin with drawing a cube on a cylinder.
This time I place it above the horizon but in such a distance that a second cube stuck
below will intersect with the horizon a little. I copy the cube downwards and then to the sides and inwards the sheet. All these cubes are going to serve me as a three-dimensional scaffolding into which
I’ll be able to put more complicated objects easily and according to perspective. I decided that my playground is going to be composed
of two towers connected with a glass tube. On one of them I planned a ladder and on the other a slide. Both towers are going to be covered with pointy
roofs, each of a cube’s height. Because only the top of the roof is going to reach the height of a
cube I don’t have to draw a separate cube for every roof. . It’s enough if I find this height over
the center of a cube’s wall below. To that end I copy a half of the cube’s vertical wall upwards and then, using perspective, get
one edge of the new surface across to exactly above the center of the cube’s horizontal wall. The higher tower is going to be covered with
a hip roof with a small eave. Therefore I outline the base square with a slightly bigger square of which vertices located on
the extensions of square’s diagonals I connect with the top point of the roof. This way I get a simple pyramid. The lower tower is going to have a coping in a form of a
cone backed off a little in regard to the side walls. Using the diagonals of the cube’s horizontal wall I draw inside it a slightly smaller square and inside that
I draw a tangential ellipse. I connect the ellipse with the top point and get the second roof. As I’ve mentioned before the towers are going to be connected with a tube.
To create it I draw an ellipse on the cube’s side wall. Like in the case of the cone roof I moved
the ellipse away from the cube’s wall’s edge. I repeat the whole operation to find an ellipse
on the wall of the second tower. I connect the ellipses and get a cylindrical passage from one tower to another. I will also add a hemispherical window in the lower tower.
I again find an ellipse on the wall. I connect the ends of its major axis with a semicircle of
which center lays on the intersection of both ellipse’s axes. It’s time for the slide now. It’s also going to be
based on two ellipses but drawn on different heights. I only want to draw the lower half of the
slide so I only connect halves of ellipses. Because I was consequently moving away everywhere with the elements of the playground from the edges of the cubes I
can now use this distance to show the thickness of the walls, the floor and the poles. Using only the directions of both convergences in perspective
and the verticals I can draw elongated cuboids that’ll be towers’ sustaining poles and then in a similar
way show the thickness of the other elements. While shading a cone it’s good to lay the lines
along its axes. Similarly while shading a cylinder. To get an impression of depth I shade the bottoms of the objects strongly. Glass and transparent elements often brighten up the elements that are behind them. That’s why I shaded the tower’s wall behind the cylinder delicately and
for contrast I shade it much stronger outside the cylinder. I can strengthen up the highlights on transparent elements with a
kneaded eraser and emphasize their curvature with delicate shading. Pay attention to how I left thin white lines
by the edges of the transparent elements. Now only some background emphasizing the horizon and lighter
walls of the playground and it’s done. That’s how my playground for children looks like but
anyone can do it their own way. It’s about using these skills, play with this perspective, modify
all of it and move it as one pleases. If you like this channel – subscribe, like
