Does anyone know of a way to force graphic objects (points, lines, polys) to scale with the map?  For example, if I zoom in tight on an area and add a polygon graphic to the map, as I zoom out the polygon stays the same size regardless of the map scale.  So if I zoom to full extent that polygon is covering a huge area, when I really only want it to cover the area I originally digitized it at when I was zoomed in tight.

So in other words, can we force the graphic to scale with the map?  Can it be forced to stay at it's same original size relative to the map scale it was digitized at?  In the example above, that polygon would appear to get smaller and smaller the further I zoomed out from the scale it was created at.

Thanks in advance for your help ...

The problem is not the same for point geometries than for line or polygon geometries.
For a line or a polygon, the geometry is defined in map coordinates so has not to change when zooming in/out.

So if I zoom to full extent that polygon is covering a huge area, when I really only want it to cover the area I originally digitized it at when I was zoomed in tight.

I am not sure to understand your need for a polygon. When zooming to full extent, the area covered by the polygon is still the same (in map coordinates) and, in screen coordinates, the polygon is smaller so I don't understand what you mean by 'is covering a huge area'.

For point geometries (and anyway for others if needed), you can look at this thread : http://forums.arcgis.com/threads/28787-Scaling-Text-Symbols
