Hi,
I'm new to sirius (and modeling with eclipse). I just did the basicfamily tutorial and built a small model with EMFtext. The idea is having 2 different types of elements (nodes) and different kinds of flows between them (5 different edge types).
Now I have two Problems.
Example with WIP workbench:
index.php/fa/17766/0/
Adding inscription to edges
The arrows alone aren't very useful so the end user should get the option to add an inscription to the arrows. For example for a material flow edge between gas station and car -> 'gasoline'. How can I do this with sirius?
Using .svg images for nodes
I want to use hexagons instead of squares or ellipses. I added them as a .png image but is there a way to use .svg images for a better scalability?
Regards
Julian

If you need specific information for an edge, I think that your metamodel need a new metaclass(let's call it Travel) linking your source("Gas Station") and target("Car") and a field(Let's say a String named "purpose") holding your information("Gasoline"). Then you will have to change the Edge Mapping in your VSM from Relation Based to Element Based and the label to display will present the field("purpose").

For the style of a node mapping, you can choose a Workspace Image style. PNG and SVG images are accepted. However, note that even if your SVG is displayed as hexagon-shaped, the selection of these nodes will still be a rectangle.

Hello,
In your creation tool, you have a "Set" task for your field
"inscription" after the Create Instance. However, I think that you
forgot to set the reference "from" and "to". By the way, are you sure
that you need a multi-valued reference for "from" and "to"? A
single-valued reference may be enough.

No it is ok.

Yes as additional set values.

As your edge displays a semantic element now (se.Relation in the domain
class of your sample), the edge creation tool needs to create an
instance. However, if your relation is contained by the source element
in your semantic model (Just guessing here, I don't know your
metamodel), the change context expression should be var:source instead
of var:container. In that case the "from" field of the location would
not be needed after all.

This should be enough for an element based tool. You can find further
information in the documentation : Help/ Help Contents -> Sirius /
Sirius Specifier Manual / Diagrams / Layer and Graphical Elements /
Edges and irius / Sirius Specifier Manual / Diagrams / Tools / Edge Tools.
You can also import with source the sample
"org.eclipse.sirius.sample.ecore.design" a VSM for Ecore models. In the
diagram description Entities, take a look to the EC_EReference edge
mapping and its creation tool(in Section Relation).
