    Selecting sketch segment from a user form

    Harold Black

      I have a user form where the user needs to select a sketch segment. Once selected, you click on accept and some calculations are performed. I'm having the hardest time figuring out the correct way to code this. Below is my first attempt taking some bits of code from a different example I found online.


          Dim swApp                       As SldWorks.SldWorks

          Dim swModel                     As SldWorks.ModelDoc2

          Dim swModelDocExt               As SldWorks.ModelDocExtension

          Dim swSelMgr                    As SldWorks.SelectionMgr

          Dim swSketch                    As SldWorks.Sketch

          Dim seg_selection               As SldWorks.SketchSegment


          'Make classes to listen for events

          Dim WithEvents swDraw As SldWorks.DrawingDoc

          Dim WithEvents swPart As SldWorks.PartDoc

          Dim WithEvents swAssm As SldWorks.AssemblyDoc



      Sub UserForm1_Initialize()


          Set swApp = Application.SldWorks

          Set swModel = swApp.ActiveDoc

          Set swSelMgr = swModel.SelectionManager

          Set swSketchMgr = swModel.SketchManager

          Set swSketch = swModel.SketchManager.ActiveSketch

          swModel.SetAddToDB True


          If Not swModel Is nothng Then

              Select Case swModel.GetType

                  Case swDocumentTypes_e.swDocPART

                      Set swPart = swModel

                  Case swDocumentTypes_e.swDocASSEMBLY

                      Set swAssm = swModel

                  Case swDocumentTypes_e.swDocDRAWING

                      Set swDraw = swModel

              End Select

              Set swSelMgr = swModel.SelectionManager


              MsgBox "Please open the document"

          End If


      End Sub


      Sub HandleSelection()


           While swSelMgr.GetSelectedObjectCount < 1



           Set seg_selection = swSelMgr.GetSelectedObject6(-1)


      End Sub


      Sub SomeCalcs( swSelSpline as SldWorks.SketchSegment)



           'rest of code in here is for calculations


      End Sub


      Function GetSplineEndPoints(segment as SldWorks.SketchSegment) as Boolean

           dim swCurve                                             as SldWorks.Curve

           set swCurve = segment.GetCurve         

      End Function


      I get an error saying


      Object variable or With block variable not set, pointing to this line set swCurve = segment.GetCurve

      I defined swCurve and segment is defined in the Function. Some how my code is not seeing my selection.
