FindClosestVertex(Entity,Point,Double) Method

Looks for the vertex of the specified whose 2D screen projection is closer to the mouse cursor.

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Function FindClosestVertex( _
   ByVal entity As Entity, _
   ByVal mousePos As Point, _
   ByVal maxDistance As Double _
) As HitVertex

public HitVertex FindClosestVertex( 
   Entity entity,
   Point mousePos,
   double maxDistance
)

Parameters

entity: The entity to process
mousePos: Mouse position (zero on top)
maxDistance: Limit the search to points at this distance in pixels from mouse cursor position

Return Value

The closest vertex, if any is found.

Remarks

The returned point is in the coordinate space of the CurrentBlockReference so, if there is a current BlockReference, to get the 3D world coordinates of the point you need to transform it by the CurrentTransformation.
