Hi Stefano,
I think this is a dangerous solution to use.
The cut action doesn't clean the models and the editor whereas the
delete action does. It's because of this cleaning that performance are
not good.
Here is an example of what can happen :
Duplicate an Internal Block Diagram (let's call them IBD-A and IBD-B)
where two properties are shown, linked together with a connector.
If in IBD-A, you cut one of the two properties :
1- In IBD-A the property cut has disapeared.
2- In IBD-B the property is still available
3- In the outline, the property cut has disappeared, but the connector
is still there, and the two connector ends are still available (with a
connector end still referencing the property cut).
You can save the model, and no error is raised.
But if you re-open your editor, you will have some graphical issues (and
maybe some models issues) because the property has not been well removed.
This example is voluntary really easy to reproduce and to solve. But in
a large models, I think the consequences can be much more difficult to
manage.
Best Regards,
Thibault

Hi all,
we have some performance issue with the deletion of an entity in a big
SysML model, in fact it can take a lot of time for a single entity, I
know that this is a known issue... however I have seen that the cut
action is much more fast.
I know that cut is different from delete, for instance it doesn't act
upon links; e.g. it is possible to cut a block and save: the block
disappear from the diagram and the model but the associated links, if
any, still remain in the model in a pending state, with source or target
empty.
However do you think is safe to use the cut action instead of the delete
as 'user-level patch'? Eventually I think it is possible to use the
cut action on the pending links through the .sysml model tree editor to
clean it...
Regards,
Stefano.
