Adds a string value to a built-in parameter.

Determines whether two solids are identical, potentially offset from each other.

Identifies if the base geometry of the wall can be represented as an extrusion.

Collects all the target geometry from the input geometry object and adds it as IFC handles to the IFCInfo.

Collects all the target geometry from the input geometry object and adds it as IFC handles to the IFCInfo.

Returns the projected area of the room, unscaled.

Splits a roof or floor element composed of planar surfaces into a set of roughly vertical extruded loops of uniform depth if possible.

Creates a GUID for the given element.

Creates a randomized GUID.

Creates a GUID from Revit project for given GUIDType.

Creates a consistent GUID for an IFC entity related to a Revit element. A "related" sub-element is one that is unique for a given type of element, and can therefore by identified by a simple index value (e.g. PSet_Wall_Common property set for a wall.) The index value 0 is reserved, as this would generate the GUID of the element itself. A listing of known sub-elements is contained in IFCSubElementEnums.cs; it is expected that this list would be maintained up-to-date, instead of passing arbitrary values into this function.

Use the internal Revit implementation to relate elements at the end of export.

Obtains a list of columns known to Revit as intersecting with this wall.

Obtains the IFC-specific information regarding the connections between this wall and other elements.

Gets the arcs associated with the plan view of a door.

Obtains the curve loops which bound the wall's elevation profile.

Obtains a special snapshot of the geometry of an in-place wall element suitable for export.

Obtains the handles representing the cardinal directions in 2D.

Obtains the handle representing the 2D origin.

Obtains the handles representing the cardinal directions in 3D.

Obtains the handle representing the 3D origin.

Obtains the IFC class name associated to the given element for the current export.

Obtains the IFC class name associated to a given category id for the current export.

Obtains the IFC type associated to the given element for the current export.

Gets the curve loop corresponding to the hole in the wall made by the instance.

Gets the sub elements from a legacy curtain element.

Gets the components of a stair or ramp.

Returns one or more properties for legacy (created in R2012 or before) Stairs.

Gets the level if by the height of the element.

Gets the curve loop(s) that represent the bottom or top face of the wall, usable to create an extrusion for the wall geometry.

Obtains the minimum height of the given FamilySymbol.

Obtains the minimum width of the given FamilySymbol.

Returns the number of non-empty, non-duplicate building stories in the file.

Gets the openings data from the element.

Returns the original family symbol of this family instance, before the instance is modified by joins, cuts, coping, extensions, or other post-processing.

Obtains the relative transform between two IfcLocalPlacement handles.

Gets the components of roof slabs.

Obtains the spatial element boundary curves as an array of CurveLoops, needed for processing into IFC-specific elements later.

Obtains the transform for the door or window instance.

Obtains the unscaled transform from an IfcLocalPlacement handle.

Obtains the unscaled transform from an IfcLocalPlacement handle without fix of direction.

Obtains the base offset of the wall.

Obtains the curve of the wall trimmed or extended according to the end conditions of the wall.

Identifies if the wall has a sketched elevation profile.

Identifies if the given curve element is generated by another element's sketch, or if it represents an independent curve element accessible directly by the user.

Checks if the region bounded by the input curve loop can be represented as the subtraction of 0 or more convex polygons from a base convex polygon.

Identifies if the wall's base can be represented by a direct thickening of the wall's base curve.

Determines if the input wall is completely removed by interaction with other elements within the given range.

Checks if wall is joined to top.

Sets the handles representing the cardinal directions in 2D.

Sets the handle representing the 2D origin.

Sets the handles representing the cardinal directions in 3D.

Sets the handle representing the 3D origin.

Converts a point from global Revit coordinates to current IFC coordinates, including scale.

Converts a vector from global Revit coordinates to current IFC coordinates, including scale.

Identifies if the family instance has its own geometry, or uses the symbol's geometry with a transform.
