If this check box is selected, the pipe class is analyzed in the PCD as shown on S.50.06. If you have defined a pipe in the nominal size range from 15 to 100 in your pipe class without having selected the filter, the PCD would show the nominal size range from 15 to 100.
But if you select the Filter check box, the nominal sizes are broken down to all available sizes as can be seen on S.50.06. Our example would look as follows:
DN from |

---|---|
