Syntax

SapObject.SapModel.PointObj.DeleteConstraint

VB6 Procedure

Function DeleteConstraint(ByVal Name As String, Optional ByVal ItemType As eItemType = Object) As Long

Parameters

Name

The name of a point object or a group depending on the value selected for ItemType item.

ItemType

This is one of the following items from the eItemType enumeration.

Object = 0

Group = 1

SelectedObjects = 2

If Object is selected, the Name item refers to a point object and the constraint assignments to that point object are removed.

If Group is selected, the Name item refers to a group and the constraint assignments to all point objects in the group are removed.

If SelectedObjects is selected, the Name item is ignored and the constraint assignments to all selected point objects are removed.

Remarks

This function deletes all constraint assignments from the specified point object(s).

The function returns zero if the constraint assignments are successfully deleted, otherwise it returns a nonzero value.

VBA Example

Sub DeletePointConstraints()
   'dimension variables
      Dim SapObject As Sap2000.SapObject
      Dim SapModel As cSapModel
      Dim ret as Long

   'create Sap2000 object
      Set SapObject = New SAP2000.SapObject

   'start Sap2000 application
      SapObject.ApplicationStart

   'create SapModel object
      Set SapModel = SapObject.SapModel

   'initialize model
      ret = SapModel.InitializeNewModel

   'create model from template
      ret = SapModel.File.New2DFrame(PortalFrame, 3, 124, 3, 200)

   'add constraint definition
      ret = SapModel.ConstraintDef.SetDiaphragm("Diaph1")

   'make constraint assignment
      ret = SapModel.PointObj.SetConstraint("3", "Diaph1")

   'delete constraint assignment
      ret = SapModel.PointObj.DeleteConstraint("3")

   'close Sap2000
      SapObject.ApplicationExit False
      Set SapModel = Nothing
      Set SapObject = Nothing
End Sub
