I have followed all the instruction from here. : http://ifml.github.io/#editor
Install the tool from the update site, creating a new modeling project and creating a core model.
The problem is 'Initialize the editor' step.
> Right-click on the sample model and select New Representation / new IFMLDiagram. Choice a name for the diagram and hit OK
But there isn't 'New Representation' menu in the list.
I can only see 'Control...' and 'Export representations as images'.
So I can't follow the next step.
