BIM Properties

The properties object (serialized as dsProps in some contexts) contains comprehensive metadata specific to the application logic and BIM data.

Properties Object

Key	Type	Description
type	String	The classification of the element (e.g., "Wall", "Slab").
keepSourceMesh	Boolean	Whether to preserve the original mesh data.
edited	Boolean	Indicates if the element has been modified.
isLocked	Boolean	Whether the element is locked from editing.
isSelected	Boolean	Selection state.
isHeightLocked	Boolean	Whether the height property is constrained.
revitMetaData	Object	Revit-specific data including path and parameters.
areas	Object	Calculated areas (e.g., bottomFace).
cost	Number	Base cost value.
constructionCost	Object	Breakdown of construction costs.
changeData	Object	Tracking for changes in volume, area, length, etc.
properties	Object	Detailed material and layer properties (see below).
structure_id	String	ID of the parent structure.
storey	Number	Storey index.
quantitativeData	Object	Geometric quantities (area, volume, running length).
slope	Number	Slope value.
profile	Number	Profile identifier.
id	String	Element unique identifier (e.g., "wl_z4ww48gox").
room_id	String	ID of the room this element belongs to.
thickness	Number	Element thickness.
brep	String	Serialized B-Rep (Boundary Representation) data.

Properties (Material/Layer Data)

Key	Type	Description
type	String	Material type description (e.g., "Exposed concrete").
layers	Array	List of material layers.
thickness	Number	Total thickness.
purpose	String	Usage classification (e.g., "External").
version	Number	Version number.

Layer Definition

Key	Type	Description
name	String	Layer name.
thickness	Number	Layer thickness.
material	Object	Material reference (type, name).
type	String	Layer function (e.g., "Structure").
thicknessType	String	Type definition (e.g., "Regular").
isCore	Boolean	Whether this is a core layer.

Quantitative Data

Key	Type	Description
area	Object	Area breakdown (bottom, lateralSurface, largest).
runningLength	Number	Linear length of the element.
volume	Number	Volume of the element.
