If a family is cuttable, the family displays as cut when the cut plane of a view intersects that family in all types of views.
In the Family Element Visibility Settings dialog, there is an option called When cut in Plan/RCP. This option determines if family geometry is shown when the cut plane intersects that family.
For example, in door families, the geometry for plan swing is set to be shown when the door is cut in plan views and not shown when the door is not cut.
This option is never made available and is never selected for non-cuttable families. For some cuttable families, the option is made available, and you can select it. For other cuttable families, the option is never made available, but it is always selected.
The following table lists cuttable families and whether the option is made available for that family.
