The element PRO_E_COMPONENT_INIT_POS defines the absolute position of the component in the absence of any parametric constraints. Its value is a ProMatrix object describing the component position. If you supply this element but no PRO_E_COMPONENT_CONSTRAINT elements, the component is assembled as packaged at this location.

If you under constrain the component, the value of this element is used in conjunction with the constraints to set the packaged position for the component.
