Find elements not used at any diagram to delete

[Matej]

Hi,

I would like to clean my model as it contains many "zombie" elements that aren't used on any of the diagrams that were created during initial phases of the analysis.

Is it somehow possible to get a summary list of elements with their use on diagrams and their relationships so I can figure out quickly which elements aren't used anywhere, do not have any special meaning for the project, and can be safely deleted?

Note: Recently I've learned that using Ctrl-Del on Diagram will completely delete the element from the diagram as well as from the model. That works for newly elements. Now I would like to clean-up the historical stuff.

Thanks and regards,
m

Use the search "Find Orphans"

Geert has the answer, but be aware that it is perfectly valid to have elements in your model that do not appear in any diagram.

Be aware of:

• used types (attribute, operations, parts, instances, ports, trigger..)
• inheritance
• etc.

Therefore I made a query to find all usages of an element. Usage in diagrams (orphanes) is often not enough.

It all depends on your modelling method.

Kind regards,

Helmut

Would be nice if you would share your solution, Helmut.

Hi,

thanks for your advice.

I am going to share the solution in the community. It consists of a query and a little script to have the query on your finger tip.

Kind regards,

Helmut
