General Board / Any way to disable auto layout when embedding...

« on: November 19, 2004, 10:40:37 am »

Is there any way to disable auto layout when embedded one diagram within another? I have a use case diagram that I want to include in another use case diagram. I drag the use case to be included from the project browser onto the containing use case diagram and get a UML diagram object, but the diagram has had an auto layout done to it, 2 out of 3 times with bad results.

Thanks for any information on this and cheers,

Uml Process / Re: Subsystems, components, packages...

Thanks Mike. Yeah, I'm just using stereotyping for now. I found a reference in the Zicom mentor saying that there was a semantic change in subsystems between UML 1 and 2, and that in 1 they were a combination of a package and a component.

Cheers,

Uml Process / Subsystems, components, packages...

« on: November 18, 2004, 07:42:23 am »

I'm just starting to evaluate EA for possible use on the requirements and architectural phase of a project. I'm trying to do an iterative decomposition of the system, as per Douglass' book (Real Time UML) or the approach being taken with SysML.
Both Douglass and SysML use components as  subsystems, while the EA example uses packages. No subsystem stereotype exists for components. My imperfect understanding is that a component-based subsystem implies the semantics that the component owns the interfaces between subcomponents, and is responsible for creating subcomponents, etc., while the package-based subsystem has no true architectural semantics.

Because of the disconnect between the EA example and implementation and the other references, I'm concerned that I'm missing something important.

Comments or advice greatly appreciated.

Cheers,
