How scale rectangle in one direction without roundness scale

Question

Property "Size" scale rectangle in two directions, like a mirror. And "Scale" distort roundness.

How scale rectangle in one direction without roundness scale without expressions?

Answer 1

Assuming this is a shape layer created with the rectangle tool, you can solve this by going to Shape Layer 1 -> Contents -> Rectangle 1 -> Rectangle Path 1 -> Size, and unchecking the icon that looks like two chain links, and then changing either of the two numeric values independently to change either the width or height of the rectangle, without changing or distorting the roundness.

Answer 2

Since copying from a youtube video is annoying, here's the expression put in content > transform > anchor point:

box_width = content("Rectangle 1").content("Rectangle Path 1").size[0];
box_height = content("Rectangle 1").content("Rectangle Path 1").size[1];

[box_width/2, box_height/-2]

Answer 3

Yeah, it's really annoying that it does that, the shape layer defaults to an anchor point that is centered in the box. The workaround that I use is to use an expression to link the anchor point the box dimensions like this:

Then I think it will work the way you want it to.

You can use the expression by following the steps below and in this screen capture video.

1. Option click to enable expressions for the anchor point of the shape layer.
2. Pickwhip to the box size to get the expression started.
3. Make some adjustments so the 2 anchor point values are negative one half of the size values.

If anyone knows an easier way to accomplish this, I'd love to learn it.
