5	Revit Category (not including annotation and tags)	Variant (usually relates to different Revit versions)	Revit Subcategories (OOTB)	Revit Discipline/s (hard coded filter list)	Architecture	Structure	Mechanical	Electrical	Plumbing	Project Browser Definition Location	Hosting Methods (ways to host this Category as a Loaded Component)	Can be System, Loaded, InPlace, or Any?	General Notes and Information, including Project-level awareness	Respect for View Range	Can be used directly in Project (without loading to other family or inplace)	Can Join Geometry in Project	Taggable	Hardcoded Parameters	Can Link an Instance Param to a Global Parameter	Cut Dominance	Can contain Adaptive Points	Can be divided into Parts	Modelling Variances	Forms can be used as a valid target for Wall by Face, Roof by Face	Can be Scheduled (in version) [Revit flavor -- RAC, MEP, RST, RVT, Any]	Can be added as an Embedded Schedule	Allows an Embedded Schedule to be added to its own schedule	Can be included in an Assembly	Is Cut by a Shaft	Built-in Category Name (visible by API)	Allow parameter binding (API)	"Can add sub-category" (API)	Reports material quantities (API)	Cuttable (API "Is cuttable")	APIObject "Is read-only"	Can be Room bounding	Ability to switch between Categories	Can have Types, Instances or both	Spatially Aware	Can add Room Calculation Point to Family (option in Family Category and Parameters)	Default IFC Export Mapping (Revit GG)	Target for these IFC Import Categories (Revit GG)	Default OmniClass Number from OOTB Family Template	Special Properties as a Host	Detected as Host by typical non-workplane based families	Option to Host Rebar is available	Has option to "Cut with Voids when Loaded"	OOTB template/s provided to allow creation of Loadable Component	Requires supporting files or certain Revit things to function correctly	Parent Category (visible by API)	Relevant Dynamo and Python details	New Category added in Revit version ####	Can be Copy / Monitored between Linked Model and Host	Revit Interference Check allowed
