MultiSelectByRay Method (IModelDoc2)

Selects multiple objects of the specified type that are 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 MultiSelectByRay( _
   ByVal DoubleInfoIn As System.Object, _
   ByVal TypeWanted As System.Integer, _
   ByVal Append As System.Boolean _
) As System.Boolean
Visual Basic (Usage) 
Dim instance As IModelDoc2
Dim DoubleInfoIn As System.Object
Dim TypeWanted As System.Integer
Dim Append As System.Boolean
Dim value As System.Boolean
value = instance.MultiSelectByRay(DoubleInfoIn, TypeWanted, Append)
System.bool MultiSelectByRay( 
   System.object DoubleInfoIn,
   System.int TypeWanted,
   System.bool Append
System.bool MultiSelectByRay( 
&   System.Object^ DoubleInfoIn,
&   System.int TypeWanted,
&   System.bool Append


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

Type of objects to select as defined in swSelectType_e


True to append the selections to the current selection list, false to not

Return Value

True if an object is selected, false if not


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 edges or vertices, then any edge or vertex found within the selection cylinder is selected.

  • Selects only entity objects, which include faces, edges, and vertices. You cannot use this function to select ISketch objects.

    When selecting face entities, RadiusIn is ignored and a cylinder of infinitely small radius is used.
