OK, I found the Smooth and Flat shading options in Blender 2.5x. However I can’t find an autosmooth option based on the angle of faces, like in older versions. Is it anywhere, or it isn’t / won’t be implemented?
If I recall correctly it is in either the ‘Object’ or ‘Object Data’ settings.
It’s in the Object Data. Problem solved. Many thanks.
Applying an edge split modifier will help break up the smoothing along angle values too.
