IMultiSelectByRay 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 IMultiSelectByRay( _
   ByRef PointIn As System.Double, _
   ByRef VectorIn As System.Double, _
   ByVal RadiusIn As System.Double, _
   ByVal TypeWanted As System.Integer, _
   ByVal Append As System.Boolean _
) As System.Boolean
Visual Basic (Usage) 
Dim instance As IModelDoc2
Dim PointIn As System.Double
Dim VectorIn As System.Double
Dim RadiusIn As System.Double
Dim TypeWanted As System.Integer
Dim Append As System.Boolean
Dim value As System.Boolean
value = instance.IMultiSelectByRay(PointIn, VectorIn, RadiusIn, TypeWanted, Append)
System.bool IMultiSelectByRay( 
   ref System.double PointIn,
   ref System.double VectorIn,
   System.double RadiusIn,
   System.int TypeWanted,
   System.bool Append
System.bool IMultiSelectByRay( 
&   System.double% PointIn,
&   System.double% VectorIn,
&   System.double RadiusIn,
&   System.int TypeWanted,
&   System.bool Append


Array containing 3 doubles that define the start point of the ray
Array containing 3 doubles that define the direction of the ray

Radius of the ray in meters

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