IClosestDistance Method (IModelDoc2)

Calculates the distance and closest points between two geometric objects.

.NET Syntax

Visual Basic (Declaration) 
Function IClosestDistance( _
   ByVal Object1 As System.Object, _
   ByVal Object2 As System.Object, _
   ByRef Point1 As System.Double, _
   ByRef Point2 As System.Double _
) As System.Double
Visual Basic (Usage) 
Dim instance As IModelDoc2
Dim Object1 As System.Object
Dim Object2 As System.Object
Dim Point1 As System.Double
Dim Point2 As System.Double
Dim value As System.Double
value = instance.IClosestDistance(Object1, Object2, Point1, Point2)
System.double IClosestDistance( 
   System.object Object1,
   System.object Object2,
   out System.double Point1,
   out System.double Point2
System.double IClosestDistance( 
&   System.Object^ Object1,
&   System.Object^ Object2,
&   [Out] System.double Point1,
&   [Out] System.double Point2



Pointer to first object


Pointer to second object


Array of x, y, z coordinates for the first point


Array of x, y, z coordinates for the second point

Return Value

Minimum distance; -1.0 if no solution


Supported input object types include:

  • swSelFACES (face)
  • swSelEDGES (edge)
  • swSelVERTICES (vertex)
  • swSelSKETCHSEGS (sketch segments)
  • swSelDATUMPLANES (reference plane)
  • swSelEXTSKETCHPOINTS (point on origin)
  • swSelDATUMAXES  (reference axis)
  • swSelCOMPONENTS (component)
  • swSelREFCURVES (reference curves)


This method includes these restrictions for drawings:

  • Cannot measure between a sketch entity and a model entity
  • Measured sketch entities have to belong to the same sheet
  • Model entity measurements are based on the model origin
  • Measured object cannot be a temporary geometric entity
