Importing into Aperture 3 from iPhoto as referenced files

Question

Apologies if this has been asked before, but I can't find anything this topic...
I've just upgraded to Aperture 3. In Aperture 2, my way of working was to store RAW images in iPhoto and import as referenced files into Aperture. This was very straightforward. Now, I have 2 problems:
1 - I can't see how to import referenced images from iPhoto. If I use the import command, my iPhoto images don't show up in the list of locations to import from; if I use the iPhoto browser in Aperture and drag from that, it imports the file into the Aperture library rather than importing as a referenced file...
2 - If I import using the iPhoto browser, not only does it import into the Aperture library, it imports the jpeg preview rather than the RAW file.
The only way I can see to get the RAW file into Aperture is to find it in the Finder then import into the Aperture library. This seems excessively long-winded and also duplicates the file, using up extra disk space.
I'm using Aperture 3.0.1 and iPhoto 7.1.5
Thanks in advance for your input

Answer 1

I have not imported an iPhoto library because my workflow is to to use Aperture for storing and archiving Raw files and iPhoto for exported jpegs.
However the instruction in the Aperture 3 PDF Manual are as follows:-
To import your iPhoto library
Choose File > Import > iPhoto Library.
Select the iPhoto library in the dialog that appears.
Choose a location for the imported images by doing one of the following:
• To store imported masters in the Aperture library: Choose “In the Aperture Library” from the Store Files pop-up menu.
• To import the files as referenced images stored in their current location on your hard disk: Choose “In their current location” from the Store Files pop-up menu.
Tip: Choosing“Intheircurrentlocation”isrecommended.Whenyouchoosethisoption, Aperture refers to the original files in their current location and does not have to duplicate the files, which doubles the disk space needed to store the files. For more information about referenced images, see What Are Managed Images and Referenced Images?
• To store imported masters as referenced images in the Pictures folder on your hard disk: Choose Pictures from the Store Files pop-up menu.
• To store imported masters as referenced images in a location other than the Pictures folder: Choose “Choose” from the Store Files pop-up menu and select a folder. Choose “No folder” from the Subfolders pop-up menu to specify that the files be stored as separate, individual files in the selected folder. You can also specify that Aperture create a hierarchy of subfolders with specific folder names to hold your files.
