LayerCollection precompose() method
app.project.item(index).layers.precompose(layerIndicies, name, moveAllAttributes);

or you could create the comp and use
layer.copyToComp(compLocation);

Is this what you're after?

app.activeViewer.setActive();

I have been putsing around with a script since CS6. Suddenly with the most recent updates to CC, BridgeTalk.bringToFront ("aftereffects"); isn't working on my pc. I have tested this on a mac and it seems to work fine however when I try on my windows 7 system, nothing. I searched through th...

I should say that in this case I am not needing to rotate what so ever. I just need to push in and out and move around the grid in 3d space. The motion tile effect works very much like the grid. There is an anchor point and a way to scale width and height from that anchor point. As a matter of fact ...
