In Feature PathFinder, select the feature you want to suppress.
Right-click to display the shortcut menu, then click Add Suppression Variable.
Choose Tools menu,→Variables to display the Variable Table
In the Variable Table, find the suppression variable you added. The variable name ends with the characters: _SUPPRESS.
In the value column, type a number other than zero (0), then press the Enter key to suppress the feature.
Tip:
A value of zero (0) for a suppression variable specifies that you want the feature unsuppressed.
Suppression variables allow you to suppress and unsuppress features using an external spreadsheet.
Suppression variables are not available for assembly features.
