Transform Page
The Transform Page is a tool page in the World Editor. It can be found under the Editor tab.
The position and rotation values are specified in the object space of the selected node.
The Copy button copies the current position, rotation, or both, depending on which radio button is selected underneath. The Paste button applies a previously copied transform to the currently selected node.
The Reset button resets the transform for the selected node to the identity matrix. The radio buttons for position, rotation, or both also apply to the Reset button so that it's possible to reset only the position or rotation without affecting the other.
The values under Size specify the dimensions of the selected node. The X, Y, and Z dimensions always refer to lengths along the object-space x, y, and z axes. The A, B, and C dimensions are used for additional lengths for some types of objects.
