Roi I check it out and you cannot find the Methods and Properties of the OLE object in the DOC. but you can use the ClassBrowse of VFP6.0 to open the Acad.tlb file to get all methods, events and properties.

The deference between the Acad14 and acad15 are in the activedocument, preferences and others objects.

You cannot do oAcad.ActiveDocument.Open(FileName) in Acad15. You need to do oAcad.Documents.open(filename,lReadOnly)
