Good news! FME 2007 Beta has what you need. The "rich geometry" has come to the rescue. (You can read about rich geometry on the fmepedia at http://www.fmepedia.com/index.php/Rich_Geometry_Model). As part of upgrading our Oracle reader to do Rich Geometry, we now support reading the measures. Just view your data in the viewer by reading it from Oracle, if you select a feature, you should see all its measures there in the geometry area of the feature information dialog. And I believe that measures are carried along through the various processing operations throughout FME. To actually get at the measures, you need to use one of the MeasureExtractors in workbench (there are a few of them depending on the kind of geometry you're working with). Rich geometry is a big deal in the new FME, not only because we can now model and store complex paths and boundaries composed of arcs and lines, but also because we can carry arbitrary numbers of measures along with these. Let us know how it goes. Dale ---------------------------------------------------------------------- Dale Lutz Safe Software Inc.
