You can restrict the printing of the dimensions to certain nominal sizes. By starting the report, you can enter the list of values that will be used.
To define the list of values, you must first create a table of type GEOM_S5020 on A.50.02 Tables.
Next, add the attribute DN (nominal diameter) to the table on A.50.03 Tables/Attributes.
Now open S.50.20 Wallthickness Geometrics, create a geometric with the table name you have specified in the previous step, go to Window 2 and enter the nominal diameter values.
