Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 23.0.0.0 (23.1.0.0)

Syntax

C#
public XYZ GetVerticalProjectionPoint(
	XYZ modelLocation,
	FloorFace floorFace
)
Visual Basic
Public Function GetVerticalProjectionPoint ( _
	modelLocation As XYZ, _
	floorFace As FloorFace _
) As XYZ
Visual C++
public:
XYZ^ GetVerticalProjectionPoint(
	XYZ^ modelLocation, 
	FloorFace floorFace
)

Parameters

modelLocation
Type: Autodesk.Revit.DB..::..XYZ
A point in project coordinates that will be projected to the slab top or bottom face.
floorFace
Type: Autodesk.Revit.DB..::..FloorFace
A flag determining whether the top or bottom face of the floor should be used.

Return Value

Slab surface point for the vertically projected model point.

Remarks

If the floor is shape edited, the surface location must be within the boundaries of a face on the slab. Otherwise the method will return nullNothingnullptra null reference (Nothing in Visual Basic).
