Thank you both for suggestions.
According to Monticello I have latest Roassal2 and yet I don't see RTMultiCompositeShape, but I would assume it should be what I was looking for originally.
In the meantime I chose to do it manually - creating a custom shape in both Roassal and Trachert:
I've done it in a single path because it seems that having multiple separate paths just creates more trouble.
========
computePath
canvas ifNil: [ ^ self ].
path := self athensCanvas
createPath: [ :builder |
builder absolute.
self ccwCirclePath: builder radius: 0.5. "building circular path with specified radius"
self cwCirclePath: builder radius: 0.48.
self ccwCirclePath: builder radius: 0.4 ]
========
But even if I could manage to do this with MultiCompositeShape I'm not sure about the rest of the shapes (see attachment).

Hi Peter,I am not sure what you try to do. Having two ellipses with the same center? But different radius?Something like that maybe:-=-=-=-=-=-=-=-=-=| v |
v := RTView new.
v @ RTDraggableView.
shape := RTMultiCompositeShape new.
shape add: (RTEllipse new color: (Color yellow alpha: 0.3); size: [:c | c numberOfMethods sqrt * 10 ]).
shape add: (RTEllipse new color: (Color green alpha: 0.3); size: [:c | c numberOfLinesOfCode sqrt * 10 ]).
v addAll: (shape elementsOn: RTShape withAllSubclasses).
RTFlowLayout on: v elements.

Hi
I'm trying to draw an ellipse inside another ellipse but to no avail. I've tried using RTCompositeShape but that just expands the size of the smaller shape. Is there something else I'm missing (like fixing dimensions so they won't get updated) or should I subclass RTAbstractCompositeShape and try to make something on my own?
Thanks,
Peter--
