Add Ability to Pull Geometry of Elements with Nested Model Elements Including Material / Subcategory Information

[enarhi]

Description:

Many Architectural models contain Facade elements with nested geometry, each with its own category used for material and graphic settings. We typically need to translate this to separate geometry for these individual components (eg spandrel vs vision glazing, shading geometry, etc), and are unable to do so directly as this information is currently lost when using Pull Surfaces, which is the only current way to get the corresponding geometry.
