Is there any way to create hand-drawn shapes using, for example, the pencil tool, and ensure that they are symmetrical about, say, the Y axis?
I want to draw a template for a new top for a glass Christmas Tree candy dish. I have a pretty good shape, but it is not symmetrical. The left side was a better fit than the right. My solution was to erase the right side (delete those segments) leaving an open shape, duplicate the shape, flip it on the Y axis, then join the two halves.
This worked perfectly, but now I want to make some adjustments. It's very tedious to repeat that process.
Is there any way to define a shape so that the right side is automatically a mirror image copy of the left side?
