Align multiple 3D layers on X and Y only
I’ve searched all over but haven’t found a solution for this…
I have two 3D layers with different dimensions, different Scale, and different Z-depths. Layer A is far in the distance, and Layer B is right in front of the camera. I need B’s anchor point to stick to A’s anchor point, no matter where layer A is positioned, without changing B’s Z-position. In other words, I need their X and Y comp coordinates to match.
Any help you can give me is much appreciated.

Maybe:
p = thisComp.layer("Layer A").position;
c = thisComp.activeCamera.position;
v = normalize(p - c);
c + v*((value[2]-c[2])/v[2])

Thanks, Dan. I couldn’t get it to work the way I wanted. But I realized I hadn’t thought this all the way through. I wasn’t factoring in a moving camera and how the position of layers would need to shift to stay aligned as the camera moved. Since I can’t have them shifting like that, I’ll need to figure out another solution. Thanks for the taking the time – I hope the expression can help someone else out.
