Modeling connection variants

Postby » Thu Mar 15, 2018 11:41 pm

I would like to model the possible configuration for connecting elements of a system. In the example below I have a CPAP Device. In one configuration it it is connected to the Mask via a single Tube. In another configuration it is connected to Humidifier which is then connected to the Mask.

How do I model these two connection variants?

The diagram below is not correct, since this representation implies the CPAP Device is simultaneously connected via a single tube and the humidifier. Obviously it's either one or the other but not both. How to correctly represent this?

Please take a look at our short video representing variants modeling with Instances:

Also, I saw that you are modeling internal system structure with Block Definition diagram (BDD). For the internal connections between subsystems you should use Internal Block Diagram:
- ... ck+Diagram

Hi Donatas,
I see that the short answer is generalization relation.
Additional question:
The video in the link above provides a method for a product which has different items in different configuration. What if I just want to analyze the variation of solutions that is proposed when the items are the same and I am just into different views of it? For now, I copy the IBD a couple of times and edit those IBD's to have different views. Sometimes I need to copy and rename entire block with its IBD and edit the IBD.
