I'll try to get some screenshots and document the conversion - could be useful for others who find the thread later.
that would be most excellent 
So start off by importing the aperture file. You need to manually select the type for this when importing.

If you have reason to change the scale to mm/inches/mills/whatnot do so in the next dialogue. The defaults were okay here.
Then import the layers. Make sure the aperture file is selected as tool table, it should be by default if its imported first.

Set colours and types of the layer in the next dialogue to make things easier.
After all files are loaded you should have something like this

Then just print to cute pdf writer or other pdf output device. Take care to check the box for "Print all data in black" and for the bottom layer check the box "print as bottom view" otherwise you'll get a mirrored image.
I'll just attach the screenshots here in case dropbox links fail at some point, but external images makes for better formatting.
