What object am I getting?

By Adam Nagy

The easiest way to check is by debugging into the code and see what object type the Watches window  shows. 

E.g. the following code ...

Sub TestObjects()
  Dim f As Face
  Set f = ThisApplication.ActiveDocument.SelectSet(1)

  Dim paramRange As Box2d
  Set paramRange = f.Evaluator.ParamRangeRect
  
  Dim oc As ObjectCollection
  Set oc = f.Evaluator.GetIsoCurve(paramRange.MinPoint.X, True)
End Sub

... would show this in the Watches window when I select the side face of a cylinder:

In case of VB and VB.NET you can also use the TypeName function to find out the type name of an object:

Sub TestObjects()
  Dim f As Face
  Set f = ThisApplication.ActiveDocument.SelectSet(1)

  Dim paramRange As Box2d
  Set paramRange = f.Evaluator.ParamRangeRect
  
  Dim oc As ObjectCollection
  Set oc = f.Evaluator.GetIsoCurve(paramRange.MinPoint.X, True)
  
  Dim item As Object
  Set item = oc(1)
  
  Call MsgBox(TypeName(item))
End Sub
