UML by Omnigraffle

Hi all,

I just bought Omnigraffle for mac, and I try to make UML diagrams (in fact I bought it almost only for this). My point is: I can’t link my classes by attribute but only the whole class to another. Which is not very convenient if you want to insert your diagram in a functional specification.

I saw on the old forum that the function has been implemented in beta 5.2.3 ( post 9 by Joel). I’m using the 6.4.1 and I can’t make it work. Has the function been removed after the Beta ? Or am I missing something (which is clearly possible as I’m a new user ?

Best regards,
