Hello Nikolay,

You can download sources of org.eclipse.gmf.graphdef.editor plugin and open 
RoundedRectangleEditPart - this class contains all necessary methods performing 
synchronization between domain model properties and figure layouting options.

In particular see refreshBounds() + all the places where this method is called. 
I have to mention that org.eclipse.gmf.graphdef.editor plugin is rather complex, 
but it is mostly generated and in additional contains such features as figure 
layout/layout data synchronization with actual figure positions/layouts. 
So, if you simply need to get x/y/width/height of all nodes from domain model 
elements you have to override refreshBounds() keeping ShapeEditPart.refreshBounds() 
in mind, but simply load positions from domain model element. In addition 
you have to listen for corresponsing EMf notification from domain model element 
+ call this method from there.

The reason why I'm mentioning org.eclipse.gmf.graphdef.editor plugin in all 
the questions about domain properties->figure layouting options synchronization 
is: you can potentially use existing code generation templates/models for 
generating your synchronization mechanizms, but you have to be ready to dig 
into this unripe technique. :-)
