Sequence Diagram Sync/Async and Time Constraints

5
replies

I have a few questions about the Sequence Diagrams as implemented in Astah.

When either a Synchronous Message or Asynchronous Message is added to a Sequence Diagram, a block of time is shown at both ends of the arrow. According to the SysML specification, it should be possible to show messages with no time block shown (indicating no duration at either end of the message). How do you hide the boxes in Astah? (I think these are called "Execution Specification" in the SysML spec). In Astah, I can't figure out how to remove, hide or reduce them to invisible size.

Second Question: According to the reference material I have seen, the duration constraint should be able to be specified for the Execution Specification time blocks. When I try to insert a duration constraint, I have to select the message arrows, not the Execution Specification time blocks. Is there way to show the duration constraint on the time block and not between arrows? Sometimes there is no arrow at the end of the time block.

Thank you.

Item flows and flow properties

2
replies

I am trying to show item flows on an internal block diagram. I have 2 blocks with Flow Properties defined:

Block 1: Output Flow Property, type "Flow Type A"

Block 2: Input Flow Property, type "Flow Type A"

There is also a block named "Flow Type A" in my model.

These two blocks are in an Internal Block Diagram. When I connect an Item Flow connector from Block 1 to Block 2, I don't see the option to set the type "Flow Type A". When the connector is selected, the only property tabs are "Base" and "TaggedValue". Base has a "itemProperty" drop down selector but I don't understand what populates that drop-down. There is also a form for "Convey" in the "Base" tab. You can Add or Delete. From this, I can see block "Flow Type A" listed, but it's not clear if this is connected to the Output Flow Property defined for Block 1 and Block 2. Shouldn't there be a restriction on what you can set as the item flow? Either define a new flow property or select from the flow properties that are already defined for those blocks? Should it also check that the in/out directions are compatible?

What is the difference between "Convey" and "itemProperty", and do either of these correspond to "item flow" defined by SysML? Normally it would be displayed with "Item Name: Item Type".

Also, if you select "New" for itemProperty when the connector is selected, it creates a new Part, e.g. "Part1:UnknownType". Can this be connected to the flow property defined for the blocks? It is impossible to remove them from the itemPropery list after they are created - I don't know where they are in the model. Also it looks like a flow item label, but the label marking the flow is edited by the Association A end. Shouldn't this be connected to the compatible flow properties for these blocks?

Thanks for any help on this.

Recepetions in Astah SysML

1
replies

Hi I am using Astah SysML 1.4.0/08f5ed. I'm having trouble figuring out how to add Receptions to block definitions. They are similar to Operations, but are initiated by a signal event instead of a call event. I see how to add Operations, and I think the way to add Receptions should be similar. Does anyone know if receptions and signals are supported by Astah SysML? Thanks for any help on this.

Wrap text and resize blocks

2
replies

Is it possible for Block names to wrap so they can be resized? The block width on the diagram is fixed to the width needed to show the Block name on one line. I would like the blocks to be resized to a narrower width, but to do this the Block name needs to adjust to multi-line.

Automatic document generation from SysML?

1
replies

Greetings,

Some other SysML tools have automatic systems engineering document generation fom within the tool. For example, you might want to generate a MS Word document of the ordered requirements or an Excel spreadsheet with a Bill of Materials for an assembly, with the mass roll up included.

What are some ways to do this kind of task?

Thanks for any ideas.

Regards, Kurt
