|I created a Yin/Yang symbol, but for some reason it has a vertical line through its center. The line disapears sometimes after I move the symbol.||It disapears in outline mode. Why is it thre? How do I get rid of it?|
The way I created the Tao: (1) circle/ellipse, (2) 2 more circles stacked vertical, center, (3) 2 smaller circles for the "eyes", (4) cut away the extraneous lines by selecting anchor points; I forgot exactly how I did this, but thus far the vertical line has not appeared, (5) Selecting anchor points again, and filling areas, until the colors look right; this involves some overlapping of colors, and is where the problem started.
I have since filled a new Tao using Live Paint, and avoided those difficulties. I'm still curious as to why the bisecting line is there, and why it disapears sometimes.
If you have a look at the strokes (ctrl Y), you may have one vertical stroke.
Or, and it is often the case in illustrator, if you have cut a circle in two parts (top left black one and the bottom right white one), you should be sure to have the length and the x position of these 2 demi-circles as entire numbers (without comma).
You can see the antialiasing by zooming in a pixel display mode (shift + ctrl + y).
