Basic Shapes

To build an arm there are two important and simple shapes you should use.

  • Circle (shoulders)
  • cylindersCylinders (upper and lower arm)

The Circlecircle (shoulder) serves as a sort of hinge where the upper arm can connect to the torso. It can be any size you want as long as you understand that the circle represents a major point of articulation for the entire arm.

The cylinders (upper and lower arm) ensure that the arms dont look floppy since they can also serve as place holders for where the bones should be. For the lower arm, one cylinder is also enough to give the arm proper structure.

Reminder: these shapes can vary is size depending on the body type being drawn.

You can work with simplified shapes so that other artists can memorize more information. You can also go more detailed, if that's what you prefer.
Different viewpoints help a lot with building a better understanding.
Drawings that visualize the functions mentioned before are always great.
