GOING AROUND IN CIRCLES, ONLY MORE SO!

The concluding section of experiences of Parabolic curves with circles begins with constructing a circle with 72 points. There is no law about "numbers" of points. 24 may be used, 36 is most common and I prefer 72 for finer line quality, design opportunity and challenge. Drawing the circle to this dimension is just like determining 36 points with just one further step as shown in the animation below.

Now we're ready for some new fun.

HOW ABOUT 3 CIRCLES?

The final parabolic structure we will compose will (1)offer opportunity for more linear discovery, (2) implement triangular forms previously learned, (3)invite design additions beyond the lines drawn, and (4)of course, test everyone's patience. So, here we go!

For 72 point drawings we used a 4" radius for the outer circle, a 3" radius for the inner circle and a 2" radius for the center circle.Yep, and there has to be 72 points on each one! (Be brave.)

Simply follow the same procedure shown in transferring from 1 circumference to another,only this time, add points to tops and bottoms of both inner circles as you move all around.

The first construction (I like to call it "eye") uses points 62, 68, 72, and 4 on the bottom half of the outer circle, and points 40, 36, 32, and 18 on the top half. As the drawing shows, the first connection moves from 68 to 54. Continue moving down the left side connecting 55 to 69, 56 to 70 etc, and stop at point 4 connecting to point 18.

Then the process is repeated on the top half, beginning with point 54 to 40, 53 to 39, 52 to 48 etc, and is completed with point 32 connected to point 18.

See why I call it "eye"?
