2DBoxReplacer
From Fmepedia
2DBoxReplacer is a Workbench Transformer.
Replaces the geometry of the feature with a two-dimensional box whose minimums and maximums are fixed values, or are taken from attributes in the original feature. Each of the parameters may either be entered as a number, or can be taken from the value of a feature attribute by selecting the attribute name from the pull down list.
To replace a feature with its bounding box in one step, use the BoundingBoxReplacer or the BoundingBoxAccumulator.
To retrieve the bounds of a feature into attributes, use the BoundsExtractor.
