Uml Process / Copying Ports
« on: May 27, 2016, 07:22:30 pm »
I have a set of blocks that I need to duplicate. Each block owns a number of operations and ports as well as relationships to other blocks. I have selected the blocks I wish to duplicate and copied them to the clipboard and then pasted them onto a new SysML BDD. EA creates new blocks and these blocks contain the operations that I had previously defined  :D, the relationships to other blocks  :D but... where are the ports?!?  ???

EA doesn't seem to copy the ports too. I tried placing the original blocks a BDD, making the ports visible by turning on (selected) structural features - so that the ports are visible on the diagram. I then tried Ctrl + dragging the block onto a new diagram. Once again, EA creates a new block with operations and relationships, but no ports?

I have tried ctrl + dragging the original ports from the project browser onto the new block but EA complains, saying I can't drop ports onto the block because it is not the owner of the ports - Yes, I know EA!! I am trying to copy the ports.

Any suggestions?

Thanks everyone - the traceability view trick is most helpful

Uml Process / Visualising Classifier Relationships
« on: April 20, 2016, 10:34:54 pm »
If I create block A in package A, block B in package B and then select block B as the classifier for block A, I'd like to see (visually) the relationship between the two elements. Is it possible to visualise classifier relationships in the EA relationship matrix (or any other kind of diagram)?

Guessing no...

Bugs and Issues / Re: Nested Ports behaviour when copying to clipboard

Yes, it seems that turning on the custom port sizing option and then oversizing the owning port stops the ports from flipping their orientation. Nice to know how to stop it. I'll submit a bug report now...

Bugs and Issues / Activity Parameters not staying-put
« on: April 20, 2016, 07:48:23 pm »
I have an activity that owns an activity parameter. When I draw an activity diagram and place the parameter on the diagram frame I locate it as required. I save the diagram and close it...

When I come back to the diagram the parameter has moved back to its original location. No matter how many times I save the diagram the parameter refuses so stay where I put it. I've also seen this behaviour with some of the control/object flows on the diagram. I've tried deleting the original parameter and replacing it with a new one but this doesn't help.

Has anyone else experienced this problem?

Bugs and Issues / Nested Ports behaviour when copying to clipboard
« on: April 20, 2016, 07:44:42 pm »
I have an Internal Block Diagram containing parts that own nested proxy ports. I am trying to copy this diagram to the clipboard and so I select the entire diagram. When I do this, all those ports that are vertically orientated randomly rotate through 90 degrees. If I select another diagram and then go back to the IBD, the ports are back how they should be... Weird...

Has anyone else encountered this?

This has possibly been overlooked. Send in a bug report and somebody will do something about it.

Bugs and Issues / Send Signal Actions on State Machines not supported
« on: March 03, 2016, 07:40:26 pm »
SysML spec 1.3 states that as well as transitions between states, it is also permitted to show Send/Receive actions to enable the modeller to show a state machine sending messages to other structures. EA does not appear to support this function properly at present as it does not allow transitions to be created from states to these model elements (by default, EA provides "Events" in the State Machine toolbox, but these cannot be connected via transitions)

Uml Process / Send Signal Actions on State Machines
« on: March 02, 2016, 10:38:04 pm »
SysML 1.3 indicates that it is legal to display Send Signal action and Receive signal actions on State Machine Diagrams (Section 13.2.1 on State Machine Diagrams). These are identical in appearance to the model elements on an activity diagram

EA will let me create Trigger and Event model elements (I think a Trigger model element is an EA invention but am happy to be corrected on that) and drop these onto the sequence diagram. However, EA will not allow me to create transitions from states to these elements.

Does EA support this?

Notes, rationales, comments etc are not represented in the project browser; despite (apparently) being stored in the same package as the diagram on which they are first created.

The inability to re-use rationale elements on multiple diagrams makes traceability and design justification more cumbersome that it otherwise might be

Suggestion: EA already provides the "issues" element which is (not a SysML or base UML element) which can be re-used in multiple elements. Why can't we have a similar capability for notes/comments/rationales, which are SysML elements? Competitor products do this (e.g. Rhapsody)  ;)

notes are better written inside the note of an element

Good point, but in this case this doesn't work because I want to link a single note/rationale element to multiple elements.

I can't understand why EA has chosen to  bury the notes deep inside the model, whereas the "issues" element is a true model element that can be located in the browser.

Although I'm not holding my breath, I've raised a new feature request:

Uml Process / Command, Rationale and Note Elements
« on: February 23, 2016, 01:00:41 am »
Is there any way to get notes, commands, rationales (etc) to display in the project browser or do you have to rely on creating a search to find them?

Background:
Often the same rationale is applicable to multiple model elements. Having a way to find them easily and drop them onto multiple diagrams makes their re-use easier...

Uml Process / Re: Sequence Instances vs Objects
« on: February 22, 2016, 08:31:35 pm »
Thanks for that - does anyone know if there's a way to convert a "Sequence Instance" into an object?

A member of our team has been creating sequence diagrams using links to the classifier, rather than instances of the classifier. Aside from philosophical discussions about whether this approach is valid or not, this isn't in line with out modelling methodology. I've managed to convert them to Sequence Instances (Right click | Advanced | Convert to Property) but EA doesn't seem to want me to let me change this to an object (Element Menu | Advanced | Change type (greyed out))
