Geolocation Entities

Revit Entities	DATAKIT Class	Remarks
Project Survey Point	Dtk_AxisSystem, in Project Dtk_Component	This point identify a real-world location in the project, see its node metadata for more information around latitude, longitude
Project Internal Origin	Dtk_AxisSystem, in Project Dtk_Component	Its origin is always set to (0,0,0), all geometry placements in the converted model are relative to this point
Project Base Point	Dtk_AxisSystem, in Project Dtk_Component	This point defines project coordinate system origin. It is offseted from "Internal Origin"

Properties and Metadata

Revit Entities	DATAKIT Class	Remarks
Project Information	Dtk_Metadata, in Project Dtk_Component	MetaDataTypeEnum::TypeFileProperty
Building element Type	Dtk_MetaData in Building element Dtk_Component
Type family	Dtk_MetaData in Type Dtk_Component
Level	Dtk_ComponentPtr	ComponentTypeEnum::VirtualComponentType. Each of those Dtk_ComponentPtr group building elements placed in the Level
Category	Dtk_ComponentPtr	ComponentTypeEnum::VirtualComponentType. Each of those Dtk_ComponentPtr group building elements of a same named category
Building element ID	Dtk_MetaData and ID attribute in Dtk_Info, in Building element Dtk_Component
Building element Associated Level	Dtk_MetaData in Building element Dtk_Component
Type properties	Dtk_MetaData in Type Dtk_Component	Property groups handled are Identity Data, Phasing, Construction, Constraints, Materials and Finishes, Mechanical and Other
Family properties	Dtk_MetaData in Type Dtk_Component	Property groups handled are Identity Data, Dimensions, Construction, Mechanical, Structural and Other
Project and Shared parameters	Dtk_MetaData

Attributes

Revit Entities	DATAKIT Class	Remarks
Building element color of applied Material	Attribute Color in Dtk_Info of the Dtk_Body, in Building element Dtk_Component	Dtk_RGB
Face color of applied Material (through paint tool)	Attribute Color in Dtk_Info of the Dtk_Face	Dtk_RGB
Building element color of applied System Type Material	Attribute Color in Dtk_Info, in Building element Dtk_Component	Dtk_RGB
Type name	Name of Type Dtk_Component
3D View visibility	Dtk_NodeConnector in Dtk_ModelDisplay
Building element visibility in default 3D View	Attribute BlankedStatus in Dtk_Info, in Building element Dtk_Component	We consider "{3D}" as the default 3D View.
Material	Dtk_Metadata and Dtk_RenderInfos in Dtk_Info	Material and its texture are available in Dtk_RenderInfos if realistic view configuration is on (see RevitReader documentation).

Other

Revit Entities	DATAKIT Class	Remarks
Project 3D Views	Dtk_ModelDisplay in Project Dtk_Component
Assembly 3D Views	Dtk_ModelDisplay in Assembly Type Dtk_Component
Linked Models (instanciated in the project)	Dtk_Component in Project Dtk_Component	ComponentTypeEnum::InstanceComponentType, with instance name being the Linked Model name. Linked Model files (.rvt) have to be placed in the same directory as the main project, at the same level.
