I just saw this error in the list of every parameters :
Outline = 'new System.Collections.Generic.Mscorlib_CollectionDebugView<Autodesk.Revit.DB.ViewSection>(FichesViews.vuescoupe).Items[0].Outline' threw an exception of type 'System.AccessViolationException' in all my section views. But I can' find from where it comes.
sorry for the double post, I can't edit my last one.
