I'm trying to add ordinate dimensions to my flat patters with a macro this is an example from Solidworks.

The two lines I have bold are causing the code keep having a run time error.

Option Explicit

Dim swApp As SldWorks.SldWorks

Dim swModelDoc As SldWorks.ModelDoc2

Dim swDrawingDoc As SldWorks.DrawingDoc

Dim swModelDocExt As SldWorks.ModelDocExtension

Dim swSelMgr As SldWorks.SelectionMgr

Dim swDisplayDimension As SldWorks.DisplayDimension

Dim status As Boolean

Dim errors As Long

Dim useDoc As Boolean

Dim arrowSize As Double

Sub main()

    Set swApp = Application.SldWorks

    Set swModelDoc = swApp.ActiveDoc

    Set swDrawingDoc = swModelDoc

    Set swModelDocExt = swModelDoc.Extension

    status = swDrawingDoc.ActivateView("Drawing View1")

    'Create ordinate dimension

    status = swModelDocExt.SelectByID2("", "VERTEX", 8.76609155372049E-02, 0.255953076919585, -499.97349537912, False, 0, Nothing, 0)

    status = swModelDocExt.SelectByID2("", "VERTEX", 9.54286078448972E-02, 0.256322967029476, -499.97349537912, True, 0, Nothing, 0)

    errors = swModelDocExt.AddOrdinateDimension(swAddOrdinateDims_e.swHorizontalOrdinate, 0.094688827625117, 0.272968021978022, 0)

    'Add an ordinate dimension

    swModelDoc.ClearSelection2 True

    status = swModelDocExt.SelectByID2("", "VERTEX", 0.101346849603139, 0.257062747249256, -499.97349537912, False, 0, Nothing, 0)

    swModelDoc.ClearSelection2 True

    swModelDoc.SetPickMode

    'Change the diameter of the circle of the base ordinate dimension

    status = swModelDocExt.SelectByID2("D1@Sketch3@2012-sm.SLDDRW", "DIMENSION", 8.78551078448972E-02, 0.275113384615385, 0, False, 0, Nothing, 0)

    Set swSelMgr = swModelDoc.SelectionManager

    Set swDisplayDimension = swSelMgr.GetSelectedObject6(1, -1)

    swDisplayDimension.SetOrdinateDimensionArrowSize False, 0.00288

    swDisplayDimension.GetOrdinateDimensionArrowSize useDoc, arrowSize

    Debug.Print "Base ordinate dimension diameter of circle for arrow: " & arrowSize * 1000 & "mm"

End Sub
