Pin a text layer to the bottom of a scaled shape layer
How can I pin a text layer to the bottom of a scaled shape layer without inheriting the scale?
Hi!
I have a shape layer (a vertical bar/rectangle) whose Y scale is driven by a JSON file, making it grow downward over time.
Now I want to place a text layer at the bottom edge of the shape, so it moves downward in sync as the shape scales. But I don’t want the text itself to scale.
The problem is:
- Parenting the text to the shape layer (or to a null object attached to it) causes it to inherit the Y scale, which distorts the text.
- Even if the null’s position is visually correct, its bounding box scales and so does the text.
What I’m looking for:
- A way to track the bottom Y position of the shape as it scales
- Keep the text moving with it but not scaling
Any expression based solutions or workarounds would be really appreciated!

You could try a scale expression like this, to counteract the scaling of the parent shape layer:
s = parent.scale;
[value[0]/s[0],value[1]/s[1]]*100You might need to move the text layer’s anchor point to the bottom of the shape layer to keep gap from changing size as the shape scales.

Thanks Dan, I should try moving the anchor point to the botton instead of the shape layer. At the moment i pinned a null layer to the shape layer and connect to the null.

Thanks Dan, i have gotten it to work. I really appreciate it. I went back and tried to just do a simple animation with on the scale on the Transform of the layer instead of the shape layer group. Then I could get the text to follow the edge of the scale perfectly. Then i addaded in the json to drive the animation.
I read some where that the scale was not as precise as the size on the shapel layer group. But i could not get it to work on there. Now it looks really good and I have built a scale aswell and got it to match perfect with the shape layer that grows downwards to illustrate diggig depth. -
This Adobe Live video was supposed to provide a solution using the new Null Positional Feature but I can’t understand these two nor did I see all the new features. I could have missed something. Perhaps others may get more mileage –
