Floor Get Normal At Vertical Projection Point Method

Return a surface normal on either the top or bottom face of a floor slab at a point corresponding to the vertical projection of an arbitrary point in project space.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)

Syntax

C#

VB

C++

F#

public XYZ GetNormalAtVerticalProjectionPoint(
	XYZ modelLocation,
	FloorFace floorFace
)

Public Function GetNormalAtVerticalProjectionPoint ( 
	modelLocation As XYZ,
	floorFace As FloorFace
) As XYZ

public:
XYZ^ GetNormalAtVerticalProjectionPoint(
	XYZ^ modelLocation, 
	FloorFace floorFace
)

member GetNormalAtVerticalProjectionPoint : 
        modelLocation : XYZ * 
        floorFace : FloorFace -> XYZ 

Parameters

modelLocation XYZ

A point in project coordinates whose vertical projection will determine the location at which the normal will be taken.

floorFace FloorFace

A flag determining whether the top or bottom face of the floor should be used.

Return Value

XYZ
Normal vector on the slab at the projection point.

Remarks

If the floor is shape edited, the floor location at which we attempt to take the normal must be within the boundaries of a face on the slab. Otherwise the method will return .
