Thanks again for answering,
I need an OMPoly object which can be formed by lines straight and lines curves. Since I cannot get the OMLines from a OMPoly given (or OMAbstractLines) in order to modify some of them by curve lines, I was thinking about joining the OMLines and OMArc (Thanks Don, I didn't know that class) in an unique shape; OMAreaList give to me the solution (Thanks Don again ;)), however, I've seen that there's no an EditableOMAreaList either an EditableOMArc, so i cannot select that shapes in order to moving, modify the shape..etc, any idea?
I was also trying with arcCalc, but i think i need a geocentric arc so I will use OMArc class.
Ben, I dont know if this could slow down the performance, but I need to try it at least! :)

Hi Ruben,
Ben has the right idea, but it also depends on if you want all the parts to be rendered the same. You can use an OMAreaList to join different OMGraphics together into one shape.
Do the lines between the points have geocentric meaning, or are you just trying to create a certain visual effect? OMLines can have an ArcCalc object set on it to create a arc in pixel space between two points. It has no geocentric meaning. Might be easier to use than defining an OMArc's parameters to meet up at certain endpoints, but defining the OMArc will give you an edge that means something - a path that is a certain distance away from a lat/lon point.

I know that in theory it is not possible since a polygon is based on lines straight but i need to be able to draw lines curved and straight. I've been reviewing OMPoly class, and i think i should modify this class to convert the straight lines in curved lines (the curved lines would be formed by OMCircle class, wouldn't be?)
