How to Draw the Pelvis from Any Angle – Human Anatomy for Artists

How to Draw the Pelvis from Any Angle – Human Anatomy for Artists


Last time we learned a whole bunch of anatomy
about the pelvis, and how a bucket can help us draw the simple forms. Now let’s take it
a step further and put a pelvis in that bucket. If you haven’t seen the previous episode about
the anatomy of the pelvis, you might get confused. This method of constructing the pelvis from
nothing is most useful when you are drawing from imagination. That’s really the goal of
this whole course – to set you up to be able to draw the anatomy of the body from the vision
in your mind. You’ll be able to construct the forms starting with the skeleton and build
the muscles over that. Premium students, you can start your first few drawings using the
3d model, but then try to do some from your imagination. You want to get this construction
down well enough that you can do it in your sleep. Ok, so let’s get started. Step 1 – The Bucket I’m imagining a 3/4 front view, pointing to
our right. It’s not tilted up or down. It’s in it’s neutral anatomical position. Remember,
a neutral pelvis simplifies to a bucket that tilts forward. But that doesn’t mean the person
is actually tilting their pelvis forward from neutral. This is not neutral. This is neutral. Let’s start with the ellipse of the top cap
– the lid of the bucket. The roundness of the ellipse will be based on how much of the
top plane we are seeing. The angle of the ellipse will depend on the long axis of the
bucket. The long axis is the line from the center of the top to the center of the bottom
plane. The angle of the ellipse on a perfectly round bucket is perpendicular to that long
axis. Now find the sides of the bucket. Make sure
you follow the original angle of the long axis. Finally cap off the bottom of the bucket. Step 2 – Cut out a Wedge After establishing the simple bucket, we need
to cut out this wedge shape from the front top half of the bucket. The edges of the wedge
align with some of the landmarks, so the placement is not ambiguous. I like to find some more
construction lines to get the placement of the wedge precise. I’ll start by gridding out the top plane.
Put a dot in the center of the top plane. Find an angle from side to side. In our case
it’s horizontal. In some cases, when the pelvis is tilted or when the horizon is above or
below the pelvis, this angle will not be horizontal. Then find an angle from back to front. I like
to continue these lines all around the bucket as if they are rubber bands. Even ghost them
in the back planes a bit lighter. Ok, so now these lines will help us take out
the wedge. The top corners are the ASIS points. That edge between the ASIS points is ? of
the way down from the center to the front. Put a line parallel to the horizontal line
and now we have the ASIS landmarks. The pubic symphysis is halfway down the front
plane. From there, wrap a rubber band around the bucket. Drop vertical lines from the ASIS points to
that rubber band. Connect these two corners, and there you go. You’ve cut out the wedge. I’m going to find one more construction line
before I move on to the next step of drawing the actual forms of the pelvis. Similar to
this front edge of the iliac crest, I want to find the back edge. This one is halfway
between the center to the back. Now, these 2 dots represent the vertical peak of the
iliac crest. From there, the crest drops down toward the PSIS points behind the Sacrum.
So, this section of the top ellipse represents this half of the iliac crest. Not, the entire
iliac crest. Now, we’re ready for the final step. Step 3 – Draw the rest of the %#[email protected]&* pelvis! Don’t worry, I am going to show you how to
actually draw this complex pelvis shape in this bucket… Let’s start from the top and work our way
down. The iliac crest has some thickness, so I’ll
indicate the top plane. from these points the crest drops down toward
the sacrum, so let’s find the sacrum. The top of the sacrum is ? of the way down the
back plane. This vertical line I drew earlier is the back plane. Ok, so ? from the top is
the top of the sacrum. Now we can drop the iliac crest behind the
sacrum. From this point of view the left side is very foreshortened and the right side is
not. This wedge shape we found is pretty much the
final shape. Just round off the corner a little bit to make some more room for the acetabulum. From there, go about a 1/3 of the way down
for the height of the cartilage. And then a v shape for the pubic arch. Follow this arch of the ischium around for
a bit and then up toward the iliac crest. The side plane of the ilium is concave. Widening
at the top to the iliac crest and at the bottom to the acetabulum. The acetabulum is the socket
for the femur bone. It’s really round and deep. And down here, since we’re looking at the
inside of this form, we’ll see this side plane that shows the thickness. A softened triangular shape for the hole. Let’s add the sacrum in the back. Draw a rectangular
shape representing the top plane of the sacrum. This top plane tilts forward more than the
bucket itself. So this line from back to front will be more vertical than the line of the
back to front of the bucket. From the top plane, let’s extrude a curved
triangular form for the rest of the sacrum. The tip of the coccyx should touch the base
of the bucket right in the center. From this front edge of the sacrum, extend
a curve around the inlet and connect it to the pubic symphysis. And finally, through this hole of the inlet,
we’re going to see the back edge of ischium. There you go! A manageable construction of
the pelvis. This pelvis has accurately simplified forms, accurate placement of the landmarks,
and accurate perspective. Basically, this method of construction enables you to manage
the complex forms of the pelvis, while keeping everything where it needs to be. Once we are able to do this same thing for
the entire skeleton. We will be able to pose the skeleton as we wish from our imagination.
Then, we can attach the muscles to the appropriate origins and insertions, and we’ll have a complete
body. All from our mind. How cool is that? Assignments So, your assignment for this week is to do
3 drawings using the 3d model. Pose it however you want and draw it the way I described in
this video. Start with the bucket, cut out a wedge, and then draw the pelvis inside.
The 3d model is available to premium students only. If you’re not a premium member, you
can download a few screenshots from the link in the description below. (insert link to
blog post here) Then, after you did 3 drawings from the 3d
model, draw 3 more from your imagination. Upload your drawings to the Facebook group
at facebook.com/anatomy4artists. This week I have 6 more examples of how to draw the
pelvis. If you want to become a premium member, go to proko.com/anatomy to get extended versions

  1. Can you do a video about painting? It's something that I struggle with and a lesson from you would be great 😉

  2. Oh, god, stop with the jokes already! (…don't!)

    srsly tho, thank you, Proko. This is going to be very helpful.
    Even more helpful would be to get that premium membership, eh? nudge-nudge
    (yes, i did share this video on facebook… figers crossed! toes too!)

  3. Hi Proko, thank you for uploading the video. I'm still struggling with overall the legs and how to draw them, so they aren't so stiffed. 
    I also have the  same problem with the arms, but not as much as the legs. 
    I think, My main issue is drawing from gesture and then to anatomy with the legs and arm. 
    I have no problem with the torso since your video the robo-bean helped me a lot.  
    Anyway thank you for all these videos.
    You helped me, being a better artist .  

  4. I was thinking: I don't need to write my thanks since it probably gets lost in all the business of Proko's life and working on it is probably a better thanks… but you know what, screams THANKS, PROKO!

  5. Hey dudes! i'm a new youtube artist and i'm taking suggestions on what you'd like to see me draw! or if you wanna learn anything 😉 Stop by leave a comment and enjoy your stay at the JP family :D! click my name for drawings and amvs!

    Thanks proko for another greatly detailed tutorial!

  6. Isn't this the method shown by Gottfried Bammes in his book "Wir Zeichnen Den Menschen" (see page 96).  Did you come up with it independently, or follow his lead?  If the former, it's another case of great minds that think alike.

  7. You know have a simple straight on Front view, Back view, and Profile view would be so helpful in the free assignment images pack.

  8. This is quite ingenious, but why would you bother?
    Why not stop with the bucket, and maybe some ovals for the femur sockets? 
    There are certain subcutaneous muscles you ignore, why not ignore the complexity of the pelvis?
    Why wouldn't a bucket marked with the origin and insertion points of various muscles do just as well?

  9. I got a little confused, this example looks cylinder. when I try to draw ellipticcylinder following same shape,It does not work.Who can give me some help.

  10. shouldn't the back edge of the left ischium be adjacent to the back edge of the right side of the ischium? I can see the back edge of the right ischium is in front of the centre line and the other side is not. Is this a perspective thing? I know there is a pointy section somewhere down there.

  11. I was a little sceptic when I first saw the construction drawing, but you went clearly and understandably through the steps. Really well done. Thanks for this video series. It has been really helpful for me this far. 🙂

  12. The pelvis is probably the most difficult skeletal mass for me to understand. Not the just the shape and design (I have that down somewhat but still needs tons of work) but, the size and placement as a whole relative to rest of the body. Especially when considering the gender differences. Eventually I'll figure it out I guess. Ow. My head.

  13. I'm honestly not sure I like this method, I've been practicing it a while but it's not sticking.

    It's more an issue of the ellipse of the bucket, for one trying to draw an ellipse is difficult let alone one with the exact proportions you need and be able to do them in them perspectives, then there's adding the side planes and bottom plane which are also difficult.
    The method doesn't feel convenient to me nor does it seem to get easier, I find it much easier to simplify it into a rectangle then anything else.

  14. Pelvis is literally my worst enemy. Even a skull is not as hard as pelvis. I cannot tell it's angle nor it's placement in 3d space, it always looks flat to me no matter how I look at it, atleast skull doesn't look like a optical illusion. I despise pelvis and really wish i didn't have to learn how to draw it, but I guess I don't have a choice if I actually want to be good.

  15. Too much information ! I will never remember all these steps! I can't even read my failed drawing facepalm there must bo some shorter way…

  16. The ellipses are in the same shape and the same direction, only the size changes.Their centers are connected into an axis. Their left-to-right and back-to-front straight lines cross each-other at this axis and at their halves(halfs?). Build rectangular plans inside the bucket using these lines. Split the bucket with an ellipse parallelar to the other ellipses(the 'rubber band').
    At the top of the bucket, on the back-to-front axis, you will draw two lines parallelar to the left-to-right axis.One is at the back half of the back-to-front, right at the middle. The other one is on the other half but this time at the end of the first third.
    Focus on this parallelar at the third. It meets the ellipse at marking dots. Link these two dots with 'the rubber band', the middle ellipse of the bucket, following the side of the bucket, as if your pen was slipping against a real bucket. Finally, where the slipping lines meet the rubber band, you created two dots. Link it.
    If my explaination is not wrong, you should have the bucket and the cut edge.

    For the rest of the drawing, I should work before trying to explain it.

    Is this comment helpful? Did I do mistakes?

  17. Hello! Quick question: when drawing a female pelvis, is the bottom of the bucket wider?
    Women in general have wider hips already, but some have very very wide hips. In these cases, does the bucket shape become wider on the bottom than the top?

  18. meh. i really like your videos but everytime you say "last time…" or "next time" I need to start searching around in your videos and on the sidebar and start guessing what might be the video you are referring to, and it gets a bit confusing because you have so many different formats. wish you would just provide a link to the video you're referring to.

  19. this was very educational as always, proko. 🙂 do you have any videos on the glutes/buttox? that might sound like a weird question to some, but these are the muscles I have the most difficulty with from imagination and I've learned the hard way that being a manga artist does not mean I should learn from other manga artists. I need to learn real life anatomy to influence my style, and your videos have been an enormous help so far. you've become one of my favorite youtubers! 😀 I hope you read this and consider covering the glutes soon, or if you already covered it I'd appreciate the link. I can't find the video anywhere….

  20. one of the best video which i have ever seen
    may somebody present me some lessens like that ????
    i could understand prespective by this video
    thank you proko

  21. isn't ASIS supposed to be on same vertical line with the pubic symphysis in natural Position? and ASIS should be at same horizontal line with PSIS in natural position? thx

  22. Great method, but there's gotta be a more concise way. Especially if you're a comic book artist with deadlines to meet. This definitely isn't happening in that particular case.

  23. I was doing the sample practice images, specifically the the second one. I got to the wedge bit, so I was about to start doing the specific forms of the pelvis. For whatever reason, I could not make out what I was seeing, making my sketch appear weird. I don't know how to explain it, but it didn't make "sense" with what I was seeing and what I was drawing. It then hit me; picture of the pelvis was being view from behing. I was drawing the front part where the cocyx was.

  24. great video but although i can see what the bucket is like aproximately, you never mention its proportion. im not some pedant i generally rough things out and draw fast but only because im relying on knowledge like that in the back of my mind.
    is it safe to assume the wide ellipse to height ratio is 2:1 (say on a female) and the max depth is equal to height?? based on the cranial unit video where the bucket is tilted?

  25. I kinda learnt to draw the pelvis from this perspective but now I gotta learn to draw it from different ones.Thank you Proko for your great tutorials!I'll do my best to learn! 🙂

  26. So there are no simple shapes. Like how the face is a circle, than an oval for the second plane, or the ribs are an egg with a curved v cut at the bottom.
    This is just, nope. All the lines crossing each other the right way and the right curves. I have trouble enough drawing the second circle on heads so that it lines up with the angle.

  27. Drawing male AND female pelvis are so different tought.
    I like how this one is synthetized tough, very clear ,basic shape rendering, good job.

  28. Does anyone understand how "side to side" and "back to front" lines on the top plane are even determined? Can they be in any direction? If you put down the "side to side" line first, is the "back to front" line the same but mirrored over the minor axis of the ellipse? I can't tell how to put these lines down because neither of them are parallel to either of the axes of the ellipse. He just seems to put them down using what, intuition?

  29. when you start to draw:
    "hands omg it's so difficult"
    when you reeeeealy start to draw:
    pelvis: "Hi"
    you: WAAAAAAAAAAHH STAY AWAY FROM ME

  30. I realized I will never draw a Pelvis and its okay, Just put flesh on the bucket and that's it, or put a pants on your skeleton

  31. My god this is hard it's not the bucket that is hard but the lines look wonky or not right

    IM NOT GIVING UP IF ANYONE HAS TIPS PLZ GIVE ME

  32. The method to find the bony landmarks of the pelvis wasn't working for me. I was struggling to get the correct shape of the top ellipse and without that shape correct, the rest of the drawing falls apart. How do you guys construct the top eclipse and ASIS on it?
