I want to create a sketch over selected surface and offset line from selected edge. And I need to draw a circle in mid point of that line.

I tried below codes,

' select Edge First
' Select Face second
Option Explicit
Sub main()
    Dim swApp As SldWorks.SldWorks
    Dim swModel As SldWorks.ModelDoc2
    Dim swSelMgr As SldWorks.SelectionMgr
    Dim swEdge As SldWorks.Edge
    Dim swFace As SldWorks.Face2
    Dim swSelData As SldWorks.SelectData
    Dim swSelData2 As SldWorks.SelectData
    Dim boolstatus As Boolean
    Dim swSketchManager As SldWorks.SketchManager
    Dim status  As Boolean
    Dim swEnt As SldWorks.Entity
  
    Set swApp = Application.SldWorks
    Set swModel = swApp.ActiveDoc
    Set swSelMgr = swModel.SelectionManager
    Set swEdge = swSelMgr.GetSelectedObject6(1, -1)
    Set swSelData = swSelMgr.CreateSelectData
    Set swEnt = swEdge
    swSelData.Mark = 1
    Set swFace = swSelMgr.GetSelectedObject6(2, -1)
    Set swSelData2 = swSelMgr.CreateSelectData
    swSelData2.Mark = 2
    Set swSketchManager = swModel.SketchManager
    swSketchManager.InsertSketch True
   
    swModel.ClearSelection2 True
    
    status = swEnt.Select4(True, swSelData)
    'boolstatus = swSketchManager.SketchUseEdge3(False, False)
    boolstatus = swModel.SketchOffsetEntities2(0.001, False, False)
    swModel.Extension.RunCommand swCommands_Edit_Select_All, ""
    swModel.SelectMidpoint
    swSketchManager.InsertSketch True
    swModel.ClearSelection2 True
   End Sub

I have 2 problems,

1. offset is not always same side. are we able to fix that?

2. I found a way up to get a mid point, but I don't know how to create circle on that point.

Could any one help with this?

Thanks
