I understand the principle of having 2 separate sets of transform controls within a shape layer... however I want to create a layer that is kind of its own entity if that makes sense?
SO for example I want to create a shape layer that will rotate around a central anchor point. I can successfully centre the anchor point of the main shape using the pan behind tool but it doesn't centre the shapes specific content anchor point. The only way I can see to do this is to guess work by adjusting the X and Y values until it kind of looks entered. IN my head I want to type in 0,0 but I realise it doesnt work this way but it seems a bit strange that I am making odd number adjustments when all I want to do centre align something. Can anyone shed some light on this for me?
That's just how it works, but nothing stops you from using additional grouping levels to build a transform hierarchy like you would with parenting or rigging in a 3D program. That way you can easily zero out things while retaining the relative positioning to the parent.
