Let's say I have a shape. A simple shape, like a rectangle. And I need to add an anchor point at an exact point of a line. I can do this by doing some simple math and use guides to mark that point, and of course it works. Or I could just zoom in until I see pixel by pixel and then place the anchor even without guides.
However, I was wondering if there's a way to place an anchor by adding a numeric input. Say you right click on a path and there's an option (if it exists probably with some key(s) combination) to add the anchor at
X px or
X % from the
top or bottom or left or right or beginning of path or relative size or whatever.
Does this (or something like this) exists in Photoshop?
