Jim thanks for the reply. Yes its all on one tab/page. I have tried grouping everything and it produces the same results. I need everything in the drawing currently to be converted into a PDF. This is the first part of the drawing and its only a day or 2 worth of work. The document is only going to get bigger from here. If I can't get this file to convert then I am going to have to start over in AutoCAD. I don't want waste anymore time working in Visio if I am not going to be able to use it.
