ProjectWithGuessPoint Method

Project a 3D point orthogonally onto a surface (to find the nearest point). This method is meant to be used when a good approximate solution for the projection is available. Throws InvalidOperationException if the projection fails.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 22.0.0.0 (22.1.0.0)

Syntax

C# 
public void ProjectWithGuessPoint(
	XYZ point,
	UV guessUV,
	out UV uv,
	out double distance
)
Visual Basic 
Public Sub ProjectWithGuessPoint ( _
	point As XYZ, _
	guessUV As UV, _
	<OutAttribute> ByRef uv As UV, _
	<OutAttribute> ByRef distance As Double _
)
Visual C++ 
public:
void ProjectWithGuessPoint(
	XYZ^ point, 
	UV^ guessUV, 
	[OutAttribute] UV^% uv, 
	[OutAttribute] double% distance
)

Parameters

point
Type: Autodesk.Revit.DB XYZ
The point to project.
guessUV
Type: Autodesk.Revit.DB UV
The calculation will look for a project near the provided UV.
uv
Type: Autodesk.Revit.DB UV %
The surface coordinates of the projected point.
distance
Type: System Double %
Holds the distance from input point to its projection.

Exceptions

Exception Condition
Autodesk.Revit.Exceptions ArgumentNullException A non-optional argument was null
Autodesk.Revit.Exceptions InvalidOperationException The projection failed.
