Hi Roland & FME'rs, I've created a custom transformer called MinimalBoundingBox which finds the smallest rectangle that encloses a feature or set of features, using the Rotating Calipers method from http://cgm.cs.mcgill.ca/~orm/rotcal.frame.html<http://cgm.cs.mcgill.ca/%7Eorm/rotcal.frame.html>It assumes that a convex feature as input, so a ConvexHullAccumulator or ConvexHullReplacer is needed first. This should solve your problem of building footprints, as well as others that I've seen in the past.

Hi everyone, Thanks for your thoughts on this - some ingenious ideas there! On this occasion I'm going to admit defeat and digitise them - I don't think there are too many of them, so I suspect it would take longer to get a script right to do it! However, thanks again. No prizes, I'm afraid... Cheers, Roland.
