Setting a Coordinate System for an Advanced Mass
The CSYS area is displayed when you select the Advanced option in the Type area on the Mass Definition dialog box. Select one of the following options in the CSYS area, to set a coordinate system:
World—Set the WCS (World Coordinate System).
Selected—Select a UCS (User Coordinate System) on the model.
The current coordinate system is the default. The CSYS collector displays the selection.
 
* If you are working on a 2D model, Creo Simulate uses the coordinate system you specified during the definition of the 2D model as the WCS.
Return to To Add a Mass to a Point or Mass Definition Dialog Box.
