Name	Occurrences	Description
Sequence
name	[0, 1]	Name
description	[0, 1]	Description
parentUID	[0, 1]	UID of the component which serves as parent element, i.e. whose coordinate system is to be used as a reference for the mass properties (CoG location, orientation and massInertia). Thus, two cases can occur: (1) it is set: local coordinate system of the parent; (2) it is not set: global CPACS coordinate system.
mass		Mass [kg]
location	[0, 1]	Mass location. If the optional refType attribute is set, it explicitly specifies whether the location of the mass refers to the global CPACS coordinate system (absGobal) or the local coordinate system of the parent element (absLocal, given by the CPACS hierarchy OR by parentUID). If it is not set, the global CPACS coordinate system is considered as default. To ensure consistency, the same settings apply as well to orientation and massInertia.
orientation	[0, 1]	Orientation. The reference coordinate system (absGlobal or absLocal) is identical to location.
massInertia	[0, 1]	Mass intertia. The reference coordinate system (absGlobal or absLocal) is identical to location.

Remarks

	parentUID not set	parentUID set
location without refType	global	local
location with refType="absLocal"	global	local
location with refType="absGlobal"	global	global

Note: The combination of location with refType="absLocal" and no parentUID is global, because the local coordinate system to which the location is referring to via refType equals the global coordinate system.

Example 1: parentUID not set and location without refType --> global
