Axis - Tangents -
page 1
In this lesson you will develop a projection that is off axis and on a tangent to the isometric plane. Let me stress once more that a successful illustrator is be able to picture what an off angle object looks like before they begin to draw. |
 |
Before we can begin you must create a set of master ellipses. Create a perfect circle by choosing the ellipse tool (F7) and while holding down the constrain key (ctrl) drag across the screen to about 2 inches (Watch the status line). Convert this to a curve (Ctrl+Q) to place 4 nodes around the circle. These nodes will be at the major and minor axis’s. |

Use the Transform Roll-up
to apply to a duplicate the following: 5 degree ellipse = 10% vertical scale. 10 degree ellipse = 18% vertical scale. 15 degree ellipse = 26% vertical scale. 20 degree ellipse = 34% vertical scale. 30 degree ellipse = 50% vertical scale. Isometric ellipse (35 degree 16 minutes) = 57.4% vertical scale. 40 degree ellipse = 63% vertical scale. 45 degree ellipse = 70% vertical scale. 50 degree ellipse = 76% vertical scale. 55 degree ellipse = 79% vertical scale. 60 degree ellipse = 83% vertical scale. 65 degree ellipse = 88% vertical scale. 70 degree ellipse = 94% vertical scale. 80 degree ellipse = 97% vertical scale. 90 degree ellipse = the perfect circle. Note: Other ellipses can be created by extrapolating the above table. |
