    Hi,

     

     

    The SurfaceDraper transformer might be a solution. Input the DEM (a raster or 3D grid points) to POINT/LINES port and input the features (points, lines, polygons) to DRAPE_FEATURES port. Then, output features will be draped i.e. Z value of every vertex will be interpolated based on the DEM.

    Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?

    You can also try using the PointonValueRasterExtracter then use a ListExploder to extract the "value" attribute.
