Place

This element places an instance of a symbol onto the timeline at a specified display depth. The display depth is a type of z-ordering where elements at a higher depth appear in front of elements at lower depths. Only a single symbol can occupy a specified depth on a single timeline until the symbol is removed with a Remove element or replaced with a Replace element. Place elements can also take basic transformation attributes. These, in general, should be used in preference to a nested Transform element in situations where the placed symbol is already defined and the bounds are known. The location of the referenced symbol can be modified with the x and y attributes, the scale of the symbol can be modified using the width and height attributes, and the rotation of the symbol modified using the rotate attribute. Note that when the width and height attributes are used for compound symbols such as MovieClips and Buttons, their bounds are calculated by summing the bounds of all symbols on their timeline or, in the case of buttons, their hit areas.

If it is necessary to specify skew attributes using differing values for rotateX and rotateY, or if it is preferred to specify an absolute transform independent of the placed symbol, then the nested Transform element can be used
