Hi

I am attempting to erase a series of polygons from a raster set.  I have ArcView w/Spatial Analyst version 10.0. 

I have converted the polygon to a raster and tried to subtract the two and have tried this code to no avail.
SetNull( Not IsNull( [PolyRaster] ), [MyRaster] )

Any help would be appreciated.

Thanks

Marcus
