ItemType

This is one of the following items in the eItemType enumeration:

Object = 0

Group = 1

SelectedObjects = 2

If this item is Object, the assignment is made to the frame object specified by the Name item.

If this item is Group, the assignment is made to all frame objects in the group specified by the Name item.

If this item is SelectedObjects, assignment is made to all selected frame objects, and the Name item is ignored.

Remarks

This function sets the value of a steel design overwrite item.

The function returns zero if the item is successfully set; otherwise it returns a nonzero value.

VBA Example

Sub SetSteelDesignOverwriteItemUBC97_LRFD()

'dimension variables

Dim SapObject as cOAPI

Dim SapModel As cSapModel

Dim ret As Long

'create Sap2000 object

Set SapObject = CreateObject("CSI.SAP2000.API.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, 2, 144, 2, 288)

'set steel design code

ret = SapModel.DesignSteel.SetCode("UBC97-LRFD")

'set overwrite item

ret = SapModel.DesignSteel.UBC97_LRFD.SetOverwrite("8", 1, 2)

'close Sap2000

SapObject.ApplicationExit False

Set SapModel = Nothing

Set SapObject = Nothing
