I am having issues manually creating a polygon that crosses the dateline (long=180). My x coordinate goes from 178, 179, 180, -179, -178, etc. Anyway, can anyone give me some guidance?

I am using ArcGIS Engine 10.0 to do so. I know how to create the polygon via code, but it is the dateline issue I am having problems with. Once it crosses to -179, there is a straight line across the screen. I am familiar with the geodesify option (for polylines) and I saw there is one for elipses, but the polygon I am creating is not an elipse.

I am using the Geographic Coordinate System.

what is your coordinate system/ Spatial reference? –  Devdatta Tengshe Aug 8 '13 at 10:05
    
"The geographic coordinate system" is a bit of a misnomer. There isn't just one. –  blah238 Aug 9 '13 at 21:03
