SapObject.SapModel.PointObj.SetSpringCoupled
Function SetSpringCoupled(ByVal Name As String, ByRef k() As Double, Optional ByVal ItemType As eItemType = object, Optional ByVal IsLocalCSys As Boolean = False, Optional ByVal Replace As Boolean = False) As Long
Name
The name of an existing point object or group depending on the value of the ItemType item.
k
This is an array of twenty one spring stiffness values.
Value(0) = U1U1 [F/L]
Value(1) = U1U2 [F/L]
Value(2) = U2U2 [F/L]
Value(3) = U1U3 [F/L]
Value(4) = U2U3 [F/L]
Value(5) = U3U3 [F/L]
Value(6) = U1R1 [F/rad]
Value(7) = U2R1 [F/rad]
Value(8) = U3R1 [F/rad]
Value(9) = R1R1 [FL/rad]
Value(10) = U1R2 [F/rad]
Value(11) = U2R2 [F/rad]
Value(12) = U3R2 [F/rad]
Value(13) = R1R2 [FL/rad]
Value(14) = R2R2 [FL/rad]
Value(15) = U1R3 [F/rad]
Value(16) = U2R3 [F/rad]
Value(17) = U3R3 [F/rad]
Value(18) = R1R3 [FL/rad]
Value(19) = R2R3 [FL/rad]
Value(20) = R3R3 [FL/rad]
ItemType
This is one of the following items in the eItemType enumeration:
Object = 0
Group = 1
SelectedObjects = 2
If this item is Object, the spring assignment is made to the point object specified by the Name item.
If this item is Group, the spring assignment is made to all point objects in the group specified by the Name item.
If this item is SelectedObjects, the spring assignment is made to all selected point objects and the Name item is ignored.
IsLocalCSys
If this item is True, the specified spring assignments are in the point object local coordinate system. If it is False, the assignments are in the Global coordinate system.
Replace
If this item is True, all existing point spring assignments to the specified point object(s) are deleted prior to making the assignment. If it is False, the spring assignments are added to any existing assignments.
This function assigns coupled springs to a point object.
The function returns zero if the stiffnesses are successfully assigned, otherwise it returns a nonzero value.
