Problem with Euclidean Distance

Discussion created by Ecoscape on Aug 11, 2010
Hi - Im using Arc10 and Im trying to use the Euclidean Distance tool (Spatial Analyst>Distance) on 3 selected points but us a polygon as the extent of the coverage. When I do this I get a result of a signle value in the raster, whereas if I do the same process in 9.3.1 I get the correct result. Has this happened to anyone else?
