ECDG #3.1: How to multiply circles

Learning how to multiply circles can help you a lot!

What do I mean by “multiply circles”?

This means how to draw two or more circles of the exact same size.

This becomes very useful when drawing the proportions guide, which has a lot of same size cricles.

You can draw all circles free-hand (recommended) or use this technique:

First draw a cirlcle and then draw a square around the circle touching its edges. Make the circle as round as you can because the ones that result from the multiplication will be as round …or not round.

Now draw two lines from corner to corner. The point where these lines meet is the center point of both the square and circle. Extend the bottom and top lines too.

You can use this technique to find the center or middle section of any symmetric shape.

We need to find the middle point at the side of the square. We’ll do this by drawing a horizontal line from the center to the side. The arrow indicates the middle part of the side of the square.

Draw another line, now from the top left corner passing through the middle point of the right side (1) all the way to the bottom line (2). This is the line that actually multiplies the circle (and the square).

After that draw yet another line, a vertical one, at the point where the multiplying line touches the bottom. This creates another square that’s the same size as the first. We’ve now effectively multiplied the square and by extension, the circle (wheel).

Draw a circle inside the second square. It should be the same size as the first one. If the first one was not so round the second will be equally not round. XD

Lets do another circle.

We already know where´s the mid-section so just draw a line from the top left corner passing through the middle point of the right side (1) all the way to the bottom line (2).

Then draw a vertical line where the previous line meets whit the ground to create another square and draw a circle inside the square.multiply circles 8

It looks tedious at first but with practice it is actually really quick to multiply these shapes.

 

Quick tip: Draw a few squares using this technique and then do your circle practice inside these. It helps you become more precise.
