Thanks for your request. Currently, SmartArt objects are preserved upon converting between formats that directly supports this feature, i.e. DOCX, DOTX, DOCM, DOTM and Word 2007 XML formats. Preserving SmartArt objects in other formats requires converting these objects to images. This feature is not yet supported. Currently, we plan to support this feature before end of September. You will be notified as soon as it is supported.
Thank you, that was all I needed to hear.
