Is there still no symmetry tool in Illustrator, or have I just missed it? I and others have requested this for years. Such basic necessity.
I see that using the Effects > Distort & Transform > Reflect creates a copy, that can be ADDED TO or altered in real time. But this seems to only work if the pen tool connects to the existing path. If I begin a NEW path, it is not automatically reflected -but I was informed that this should work. I suspect I'm missing something on this.
