Area of interest (AOI) not cropping properly

Using Arcscene 10.1
I have an SRTM tile and have selected an area of interest. (using the AOI button and hitting enter.)
This crops the SRTM to the area that I need.
However, when i try and create contours (Spatial analysis>Surface>Contour) it created contours for the whole tile and nothing happens when I try and use the AOI tool.

Any suggestions as to why?


Thanks

So i just used 'XTtools" to clip the map in arcmap and then put it into Arcscene.

is there an easier way though?

AOI tool with ArcScene is to limit the display, but not the processing.  If you would like to limit the processing of the contour tool, then use the Output Extent that is respected by the tool.

also remember to set the SnapRaster equal to your input raster otherwise Resampling (using nearest neighbor) will take place.
