How to make 'composition connections' between constraint blocks?

[Fuglekongen]

Hello all

I'm currently following the guide for 'Creating a Parametric Model' for version 15.1 (I'm on 15.1.1528) found here https://sparxsystems.com/enterprise_architect_user_guide/15.1/model_simulation/create_paramet_model.html.

However in the section 'Connected Constraint Properties' there is a picture of the bdd 'ConstraintBlockDefinedByConstraintProperties' with some 'composition connections' between the constraint blocks as seen below. 



How can I make these connections?
I assume the constraints from K1, K1MultiplyK2, K2 are 'inherited' by K due to the connections?

I'm rather new to EA, and I feel that this is a total beginner question, but I haven't been able to find an answer using Google, Youtube, or the search function on this forum.

So I hope someone can help me out. Thanks!
