Opt fragment type in sequence diagram?

General Questions/Discussions
1

Hi there!

I’m currently in the process of setting up a sequence diagram but I’m a little stuck. It seems that SDE supports some fragment types but I was unable to spot the “opt” type. I did find the “alt” type which basically portraits an if … then … else … situation but right now I’m looking to add a mere optional part in my diagram. So, an “opt” fragment type with no further “else” conditions.

I was kinda hoping that the “frame” element would allow me to define an opt frame but that isn’t going to work out :wink:

So my question basically is if its possible to setup an opt frame right now. And if thats not the case if its possible to add this functionality somehow ?

With kind regards,

Peter Looyenga

Hi Peter Looyenga,

Thanks for your post. You can right-click on created “alt” fragment and select Operator Kind > opt in the popup menu. Operator Kind can be selected in fragment’s specification dialog as well.

Hi Fiorella,

It is available in the Format Panel upon selecting the combined fragment:
