The relationship (association) in the "Block Block Composition Pattern" shows an arrow whereas selecting Part Association (Aggregation) does not.

1. What is the meaning of the arrow? Is it significant?
2. If the arrow is significant, where do I select this in the Toolbox?

I cannot find details in the user guide but please point me in the right direction if I missed the documentation.

Thanks

Dana

From a guess: check the tagged values whether there's some in/out value you can set. Likely this is a shapescript reacting on a TV.

Hi,
correct sysml implementation should have the arrow AFAIK.
Missing that arrow is some kind of EA bug.

You can have the arrows just by changing the right end of the association from Navigable to Non-Navigable and back to Navigable.

However for me it is not worth to do that. So all my blocks do not have that arrow at all.
Best regards,
