'end surface' should be written without space; the 'end' hadn't been recognized as a keyword and therion expected another row of numbers. If you want only to display scanned map, grid-units and grid commands are not necessary -- they are only used in 3d model. > b) at loops: is the standard error for the measurement devices > included when the loops are closed?
