I was curious how I can find the dimensions of a shape layer. The reason I need to know is because I need to scale a shape layer, but I want it to scale from the left, not from the middle. I know how to do that part, all I have to do is divide the length of the shape layer in half, and add that keyframe the position. However, the problem is that I can't actually find out how to get the dimensions. If someone could help, that would be great. Thank you :)
EDIT: I found this solution that supposedly works here. But I don't actually know how to insert that expression, If someone could either find a different solution or tell me how to insert that one, it would be so helpful.
