FME Surface Modeller “minimum number of points”
IN FME workbench 2016.1 I want to create a DEM from Multipatch-geometry contained in a geodatabase, for doing that I thought using the surface modeller could work, where in surface modeller I group the points by the UUID generated attribute:
But the errors are
The specified cell size of '2' units in the y axis is invalid. Cell size must be less than raster extents
Surface Model cannot be constructed. Either all points are linear or initial set of points did not consist of 3 non NAN elevations
For the first error I think it's due to objects with 3 points in less than a diameter of 2 meters
Second error is due to objects with less than 3 points
Questions:
1) how could I exclude/drop/ignore geometries with less than 3 points ?
2)how could I still add a cell value to objects less than 2 m ?
