SelectByRay Method (IModelDoc2)

Selects the first object of the specified type that is intersected by a ray from point (x,y,z in meters) in direction vector (x,y,z) within a distance radius.

.NET Syntax

Visual Basic (Declaration) 
Function SelectByRay( _
   ByVal DoubleInfoIn As System.Object, _
   ByVal TypeWanted As System.Integer _
) As System.Boolean
Visual Basic (Usage) 
Dim instance As IModelDoc2
Dim DoubleInfoIn As System.Object
Dim TypeWanted As System.Integer
Dim value As System.Boolean
 
value = instance.SelectByRay(DoubleInfoIn, TypeWanted)
C# 
System.bool SelectByRay( 
   System.object DoubleInfoIn,
   System.int TypeWanted
)
C++/CLI 
System.bool SelectByRay( 
&   System.Object^ DoubleInfoIn,
&   System.int TypeWanted
) 

Parameters

DoubleInfoIn
Array of 7 doubles: 3 for the start point of the ray, 3 for the direction of the ray, and 1 for the radius
TypeWanted

Type of objects to select as defined in swSelectType_e

Return Value

True if a selection is made, false if not

Example

Remarks

This method:

  • Defines a cylindrical region of infinite length that begins at pointIn, runs parallel to VectorIn, and has a radius of RadiusIn. If you specified edge or vertex entities, then the first edge or vertex found within the selection cylinder is selected.

  • Only selects entity objects, which include faces, edges, vertices, and so on. You cannot select ISketch objects using this method.

  • Does not support the selection of silhouette edges.

Only a single entity is selected within the distance radius regardless of multiple entities existing within that radius. For selecting face entities, RadiusIn is ignored and a cylinder of infinitely small radius is used.

Use model space view to determine the selection vector in a drawing.
