Surface.ProjectWithGuessPoint

Method

Description:
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.

Syntax

public void ProjectWithGuessPoint(
	XYZ point,
	UV guessUV,
	out UV uv,
	out double distance
)

Public Sub ProjectWithGuessPoint ( 
	point As XYZ,
	guessUV As UV,
	<OutAttribute> ByRef uv As UV,
	<OutAttribute> ByRef distance As Double
)

public:
void ProjectWithGuessPoint(
	XYZ^ point, 
	UV^ guessUV, 
	[OutAttribute] UV^% uv, 
	[OutAttribute] double% distance
)

member ProjectWithGuessPoint : 
        point : XYZ * 
        guessUV : UV * 
        uv : UV byref * 
        distance : float byref -> unit

Parameters

Parameter	Type	Description
point	XYZ	The point to project.
guessUV	UV	The calculation will look for a project near the provided UV.
uv	UV	The surface coordinates of the projected point.
distance	Double	Holds the distance from input point to its projection.

Return Value

Exceptions

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