General Board / Find opened diagram in browser
« on: May 19, 2011, 10:23:56 pm »
It doesn't seem to be possible to show the diagram that's currently opened in the Project Browser as available for Elements
It may sound useless as you open in the 1st place the diagram from the project browser, but.. if you have a hyperlink from a diagram opening a new diagram, it could be useful to show the current diagram in the browser

does it sound like a feature request if not avail?

General Board / Re: Red arrow above requirement

Thanks, it's actually explained in EA Help.
A red triangle above an element means that it's been bookmarked.

General Board / Red arrow above requirement

I sometimes get a red arrow on the middle top of some of my requirement elements when displayed in a diagram, but cannot figure its meaning.
Any clue?

General Board / Interaction overview diagram in EA 7.5 build 850
« on: April 27, 2011, 03:36:14 am »

I'm using EA 7.5 build 850 that oddly doesn't support object flows between interaction occurences (e.g. linked to a sequence diagram)

I tried on an earlier version of EA and it works.
Is there a workaround to get it to work on EA7.5 as I cannot upgrade the version on this specific PC I'm using?


General Board / Display both the Title and Alias for a Requirement
« on: April 18, 2011, 11:36:46 pm »
I needed to display in a requirements diagram both the name and the alias for each requirement.
I thought that EA only let me display either way
I eventually found a way to this issue for anyone who has the same need (or requirement...  ;)) :
- In your Diagram properties, enable Use Alias If Available
- In Tools > options : Diagram > Behavior > Alias usage : select the option "Alias and Name"

My question for a related need is whether I can display in EA Project Browser the alias for each element in addition to its name and  stereotype


General Board / Re: profile based on SysML Block Definition Diagra
« on: April 15, 2011, 11:52:29 pm »
I guess that if you need to use SysML and define stereotypes on its meta classes such  as Block, you need to have the proper edition of EA (Ultimate or SysML addon)

General Board / Re: 4+1 architecture

Hi Rob,

to answer your question, I would identify all use cases in EA.
This is what I do for all my projects ; use cases allow to define the scope of your system

You don't have to go into details for each of them (e.g. describing all scenarios and their steps)
Once you have all your use case items, you can build your traceability through dependency associations with other elements of your model.

Hi Rob,

I never used the 4+1 model in a given project but did some investigations a while ago for a prospect client and it doesn't seem far from what I'm doing in EA currently i.e. requirements model, analysis model (use case, ...), design model, and architecture model.
The core of my EA project is traceability e.g. from requirements to use cases, by instanciating an object from a class, etc.

In the 4+1 model, if asked to apply this, I would create the following using EA when suitable EA default models :
- a use case model (the "+1" model)
- a domain/class model = logical view
- a business process model = process view, for my activity diags
- a component model = the dev view (component diagrams)
- a deployment model = physical view (apply components to nodes)

Of course this is just the EA project template to start with. The processes involved in running your project are to be defined and followed in a manner that makes use of your EA project structure, adapting it when necessary. However the project should be lead by the use cases and its scenarios

General Board / 4+1 architectural view EA project ?
« on: November 15, 2010, 11:18:46 pm »

I'm likely to use the 4+1 architectural view project (for any information, check out Wikipedia

EA has this listed in its list of project samples but it only generates empty project (with Logical, Process view, etc.)
Has anyone used this approach and could share a sample project ?

Thanks!  :)

Will do


General Board / Re: SysML Simulation : output of 1.#QNB  value
« on: October 08, 2010, 06:59:13 pm »
The engine running for the SysML simulation seems unstable.
When running the simulation from my parametric diagram, having updated the values and script, I'm currently getting an SScripter.exe error ("memory cannot be read")

Any idea?

General Board / SysML Simulation : output of 1.#QNB  value
« on: October 08, 2010, 03:28:00 am »

I'm trying out SysML parametric diagram and EA simulation module for a customer.
I defined the script for my constraint block before creating my parametric diagram.
When I instantiated my constraint block as a constraint property, put my parameters and entered values in the simulation module, it worked ok

I then instantiated my constraint block again to create a second constraint property - for some odd reasons, I'm now getting values with 1.#QNB

any idea what's going on?

General Board / Re: UML Profile for SCRUM ?
« on: March 09, 2010, 09:00:57 pm »

There is an approach in terms of generating sufficient (not too much) models/docs for SCRUM, introducing the concept of the following:
  • Spec user stories (e.g. scenarios under use cases)
  • Features
  • Tasks

Basically all is available under EA to do this, but a UML profile would be useful especially if it's been tried and tested
Hence, if a UML profile and possible base project structure is available; it'd be useful.


General Board / UML Profile for SCRUM ?
« on: March 09, 2010, 06:55:23 pm »

I'm looking at using EA with an agile project involving SCRUM.
Does anyone know if a UML profile is available somewhere to support the SCRUM framework, e.g. product backlog, user stories, features, tasks...


General Board / Tagged values and CSV export/import
« on: March 17, 2010, 01:44:02 am »

I created some tagged values in a number of packages that I'd like to include in my CSV file when running a CSV export.

EA doesn't support this and I was wondering if it could be added?
e.g. export Name, ..., Tagged value 1, Tagged value 2, ..., Tagged value n
