How to Draw Structure in the Body – Robo Bean

How to Draw Structure in the Body – Robo Bean

In this episode we’ll add structure to the
bean to create the robo bean. If you haven’t seen the bean, structure or
landmarks videos, you might be a little confused with some of the things in this video because
we’ll be taking the bean and adding structure to it based on the landmarks. so click to
watch those now! Why use robo bean? A few weeks ago we met the Bean. After you’re
comfortable with the bean, it’s time to move on to his friend, Robo Bean. The robo bean
is great because it combines the motion from the bean with 3d form. Now we’re able to show
the side planes to show rotation and top or bottom planes for tilting and leaning. These drawings are gonna be extremely stylized
and by no means is it a finished drawing or how I’m saying you should draw. This is however
exactly what I’m thinking about when I analyze the form. So showing this simplistic exercise
is a great vision into the thought process. It’s also just a really good exercise to practice
to see and draw three-dimensional form. You should be able to freehand cylinders and boxes
from any angle and get the perspective right as I explained in the structure video a few
weeks ago. Review cylinders and boxes This exercise is very similar to the bean
exercise except now instead of using balls we’re gonna use boxes. Boxes are little bit
more advanced, but more effective because now you have plane changes to better explain
the orientation of the forms. Spheres are not effective in showing perspective as I
explained last week. You can’t see a sphere as three-dimensional unless you add tone.
Without tone a sphere is just a circle. A cylinder introduces perspective because it
has a plane change at the top and bottom. A box shows even more perspective because
it has a plane change from the front to the side plane, along with top and bottom planes. Landmarks Ok so let’s take a look at the details of
the robo bean and what exactly the boundaries represent. The top box is the rib cage and
a portion of the shoulders. The bottom is the pelvis combined with the butt. Remember those landmarks we went over last
week? Well they’re really going to come in handy as you construct the robo bean. Almost
every edge or corner falls on a specific area along the body. Let’s start at the top! The top front corners of the first box align
with this corner on the clavicles. At the bottom, the corners of the 10th ribs indicate
the bottom of the box. These 4 corners give us the front plane of the box. On the backside,
the ridge of the spine of the scapula provides the edge between top and back plane. Just
stretch that back plane to the length of the ribcage. Sometimes it’s hard to tell exactly
where those corners are because the ribcage in the back is covered by the muscles. But
the exact points are not important. Just make sure to get the length and angle correct. The top plane is everything between the scapula
and clavicles. You have to ignore the trapezius muscle to see this. This is a very important
plane to show when the body is leaning forward or backward toward us. Usually I’ll even extend
this to the edges of the shoulders, but we’ll save that for the mannequinization video. Connect the side planes for the sides of the
ribcage.. And the bottom plane doesn’t matter much. The space between the boxes is filled
with guts and other fun stuff. Lets move on to the bottom box. The most useful corners, I feel, are the ASIS.
The corners on the front of the pelvis. They’re extremely important to find the angle of the
pelvis. Unfortunately, there aren’t any good points to indicate the bottom of the front
plane. You’ll just have to use your imagination and extend them from the pubic bone. Follow
the edge of the iliac crest until the PSIS for the side planes. The back plane starts
at the PSIS and includes the mass of the gluts. The rounded part at the bottom of the gluts
is the edge where you can show a bit of a bottom plane. And again, the top plane doesn’t matter because
of the guts thing. Together all these points form the two boxes
connected by the spine, which moves the boxes. Differences between genders The proportions are going to vary from person
to person. That’s why its good to know what landmarks youre looking for on the body. So
that you can analyze those points on the person youre drawing and measure the proportions.
Generally, the ribcage and pelvis on a male are about the same width. On a female the
ribcage is thinner and the pelvis is wider. There’s variation within genders – some men
have wider hips and some women have wider shoulders. Mentally identifying the body type
before you draw it will help. Motion With the addition of the top, bottom and side
planes we can show the motion and position of the body with more detail than with the
bean. The corners help to show the tilt side to
side with the angles from one side to the other. The top and bottom planes help to show the
leaning forward or backward And the side planes help to show twisting. More about the Twist This brings me to an important part about
the twist that I forgot to mention in the bean video. I showed with the towel that the
overlaps come from the corners that are closer to us. This is true from the side view of
the torso, but from front or back, its actually the opposite! Here’s a better explanation
for getting the overlaps right.. figure out which side of the body you’re seeing
completely. The overlaps are the ones parallel to this rhythm. If you’re looking at the side, then the side
plane is being twisted like this. And the front and back plane will wrap back around
the side plane. If you’re looking at the front plane, then the same thing happens here, but
now the side planes wrap behind the front plane and the center line is following this
S curve rhythm. So basically the overlapping lines are going
to follow the rhythm of the plane we’re looking at. With the robobean its actually much easier
to see why this happens. Here the side plane is wrapping behind the front plane, so this
edge would overlap this one. On the other side same thing.. Assignments, Critiques and Giveaway! Alright so the assignment for this lesson
is pretty obvious.. Just find some poses (plenty available at and draw the
robo bean for that pose… You’ll probably have a bunch of questions, concerns, mistakes
you might have made. So, next week I’ll post examples of me drawing the robo bean which
hopefully will address some of your questions.. Also, keep submitting your exercises for critiques.
I’m going to combine the submissions from the bean, structure, landmarks, robo bean
and mannequinization lessons into one critique video.. Since all these lessons are related
to building forms. So if you want to submit for a critique – do
the assignment from this week’s lesson. Post your drawings on your Facebook page, tumblr,
blog, forum, wherever you like to post your artwork. In your post make sure to mention
this video and include a link to it. Email me and tell me where I can find your drawings.
Make sure to follow the guidelines that I describe on Aaand.. Giveaway time… 3 lucky, super awesome,
hardworking students who submit for critiques will get free access to the Figure Fundamentals

  1. Ciao Proko, vorrei acquistare il tuo corso "Figure drawing fundamentals" mi puoi spiegare come è possibile tradurre i commenti in lingua Italiana. Grazie

  2. Thanks Proko! I'm using the tools you used to understand the twist and the bean more, which I put two balls in a sock and tied a knot at the top for the base of the head. It actually really helps me visualise the simplified form a lot more plus I can treat it like a life drawing class. I do this with a rag and a black line for the twist like what you used.

  3. Hey Proko!
    Is there like a specific order of drawing the human figure? Like first, you draw the gesture and then you proceed to the bean and then robo bean?

  4. Should I put some roundness when I'm drawing a robo bean, for both the rib cage and the pelvis? Or can I draw it as a stiff rectangle and cube? I'm just wondering, because I like adding roundness to a bit, and I don't want to draw the regular bean, because the robo bean allows me to see each angle.

  5. One of the best channels out there! I just purchased the Sekaa pack and looking forward to hard practice. Keep up the great work Proko!

  6. Thank you for the wonderful lesson's, they help remind me of all the tips & tricks to being an artist. You are pretty silly to which helps keep me entertained while I learn, keep them coming thanks again.

  7. Warning to all aspiring artists: do NOT skip this exercise! This is my 2nd try on Stan's courses (I was kinda impatient the first time) and in a few days I've noticed my lines have become more purposeful and meaningful. Thanks, Stan! You're the man!

  8. you know what would be cool? to have a model of the skeleton with the cube overlaped to see the matching points, that would be an awesome reference

  9. Hey Proko, I am a traditionally trained artist with a bachelors degree in art, and i KNOW all the information about structure and anatomy that should be able to make me draw and sculpt well but i hit a wall because of my proportion blindness. My lines are sloppy and I can't even draw a circle well, and i can see when something is wrong but i can't seem to draw it right. Even referential tricks like the robo bean and the loomis head come out proportionally wrong. When i focus too hard, it just makes my eyes hurt and gives me a headache. This has caused a plateau in my work for years that has impeded my ability to improve. Is this due to a disability and how can i get past this?

  10. Stan's last name sounds like a rubber ball bouncing off the floor , hitting the wall and then falling on the ground , lol

  11. Thank you! I’ve been taking a life drawing class with little or no instruction. Your videos are fantastic.

  12. 😉😉😉😉😉😉😉
    Suggestion , if you really want to learn drawing :-
    Don't read the comments , they all are filled with NEGATIVITY.
    You will be demotivated after reading the comments and won't be able to draw.
