Capella diagram optimization questions

Hi everyone,

I’ve been using Capella lately to create the operational analysis of a complex system, and I have several questions:

1. [In one click or simply-using a shortcut ] Is it possible to hide elements from a Capella diagram by their type (e.g. actors/entities from an Operational Capability Blank (OCB) diagram) ?
2. Is there a recommended trick or rule-of-thumb to optimize the layout of my diagrams? Actually, after integrating all the “involve relationships” in my OCB, UNFORTUNATELY, my diagram looks like a spaghetti. Worse, when I try the “Layout All” button it becomes a total mess :man_facepalming:
3. Finally, I’ve observed that sometimes the last letter of my labels gets hidden given an impression that there’s a typo mistake, despite maximizing the box size without progress. It appears to be a rendering issue, is there any known fix for that?

Sorry for asking many questions, I’m trying to make my diagrams user-friendly to encourage adoption of MBSE with Capella

Best regards

Hi there,

1 - See image below (and then Ctrl+H for hiding)

2 - I would look at this thread: Alignment of functional chain

3 - Please provide a screenshot/video (using screenToGif for instance)

All the best,

Stephane

Q1… there is a toolbar at the top with a “filters” option. This will allow you to hide different elements on the diagram as you need.

Q2… It is easy to try to create “one big diagram” with everything on there. This is very hard to keep tidy. Try breaking down your system into smaller diagrams, modelled per capability, component etc. Have diagrams that show the structure, have diagrams that show the functions etc. Always think, “what story am I trying to communicate?” And create a diagram that tries to tell this story. This will lead to more focused diagrams.

Q3. Not something I have personally seen before.

Hi Stephane, thanks for your support
The bug with the hidden letters happened again, and I recorded this GIF

Thanks, indeed, not sure what is happening here. Could not reproduce it…

Which OS are you using?

I’m using Windows 11 Professionnel and the issue appeared in an external monitor

and what is your scaling setting in windows for this monitor? 100%?
