I have created a simple composite simulation two different ways. One of them was created by defining the shell from a surface body. The other was created by defining the shell based on faces of a solid body. When attempting to create a FOS plot for the surface body-derived study, the Composite Options are not available. These options are only available when the study is derived from the solid body. It seems crazy that you cannot perform a composite study based on a surface body since the thickness of the solid body is irrelevant. Is this actually the case, or

am I missing something? Thanks
