I have a an object and i want to move the anchor point to the horizontal and vertical centre so that i can then align it with other shapes.
How do i do this?
the anchor point
the horizontal and vertical centre
The object that the Anchor Point belongs to may be aligned with other objects in various ways including by its centre without anything being there.
I think you must mean Centre Point (which isn't an anchor).
It is in the centre of an object's rectangular bounding box and therefore not necessarily in the geometric centre of the object itself.
