Very informative stuff. Needs hours to review and unpack. Thank you.

[@johngibney2932]

Thank you for going slowly as you selected the menu choices in Cameo. Other videos on this topic produced by others make their selections so quickly it is hard to grasp what's going on or remember how to repeat the procedures used. Your video was the right pace for me. Thank you!

Thanks, John. Glad to hear it was a good pace!

This is a HUGE help in unpacking metachain navigations. Thanks so much!!!

[@brianMoberley]

You’re very welcome! Glad this was helpful. Thanks for watching!

If you have several owned elements or attributes in a field that are different value types, how would you go about filtering value type by name to create separate columns in a table for each?

[@brianMoberley]

Xavier, thanks for watching. Great question, you can do that with a filter and a type test. Here’s a video on that topic: kzbin.info/www/bejne/onbShHacf5l8faM

very helpful Thank you. I do have a question based on those operations you showed. It is possible to apply these expressions to filter a diagram? For example, let's say I have an IBD that shows connections with voltage and data flows. The voltage connects could have different values. Is there a way to show/hide all but a specific selected voltage connection? Say I want to go from the diagram view that shows all voltages to showing only the 10 V flows on the IBD? I used SparxEA years ago and there was a way to do something like this, but I can't find if it can be done in Cameo/MSOSA. Thanks again.

What if you wanted to query the parent or child requirement text to see if it contains a will anywhere in the text?

I need to know how to use concat option

Is it possible to query inherited relationships from an element? For example, say a requirement is satisfied by a value property owned by block A. And say block A has a base classifier to block B which inherits the properties and relationships of block B. Then block B has a base classifier to block C which also inherits info. Thus, block A will have inherited relationships from block B and C. Could I query in a single column all of the inherited relationships in block A starting from the requirement?

[@brianMoberley]

Taylor, yes, this is definitely possible. Have you tried the “All General Classifiers” option? I believe that will only query the direct generalization in which case you’ll need to do a Union of that result with a another Metachain that looks at reaches all the way out to the general classifier of the general classifier.
