On the home screen and template dialog of SmartDraw, select Add Service and choose Dropbox®.
Alternatively you can also add a new service like Dropbox right from the Save As dialog. Just click on the logo or Add New under the Save To drop down.
Next, login to your Dropbox account.
SmartDraw will automatically connect to your DropBox account.
You can now save any diagram to Dropbox using Save As in the File tab.
Once connected, you can also see and save to any shared folders you may have on DropBox. Regular folders will appear in gray while shared folders will be in blue.
Any diagram saved to DropBox will also bear the DropBox logo in the template dialog to help remind you where your files are being saved.
