A doubt has arisen when trying to represent centroids. I need a dynamic layer, so that they represent a series of ellipses, appear us centroids (without having to select). More details:
Ellipses layer is the functional layer and the layer key. Is a layer containing ellipses and constantly changing, as are continuously added, modified and deleted ellipses.
I thought to add a layer of points, new shape, but not a good idea because it would only serve to a point in time. Must be something dynamic and fast, that does not involve the creation of a new shape.
Against this, another solution would be to create a tool with a button to click on the button is drawn to the center (cross) of all ellipses that are drawn and re-click are disabled. Suffice to bring up a cross ArcGis style when selecting the ellipse (imagine that it can be used any of the options in ArcGIS).
Can you solve it?
