Arcs #1

Besides simple rectangles, triangles, and other poly-sided shapes, we can also create arcs or curves.

Starting with a path command, we use the a or A command to draw elliptical arcs - sections of an ellipse that connect 2 points.

Note that an ellipse may have an equal x and y radius - thus becoming a circular arc.

In Example 1 we use small a to specify relative coordinates.

In Example 2, we use A to specify absolute coordinates.

Example 3 introduces Z - the closepath command. Use this command instead of drawing a line to the beginning point.

Example 3.1 shows how a circle can be created by specifying the x and y radius the same. Normally we would use the circle command, as in Example 3.2.

Example 3.2

Example 4 combines several individual curves into one. Each curve is colored differently to distinguish it.

Create a vertically linked set of arcs as in Example 5.

Finally with Example 6, we link arcs on an angular path.
