You can clone a part filter contained into another specification if you need some of
its filter units. This avoids creating a part filter and having to fill all of its attributes
before duplicating the units from one part filter to the other one.
In the Engineering Specification Data tree, double-click a part
filter to edit it.
From the Engineering Specification
Edition section of the action bar,
click Create Subfilter.
The part filter is duplicated in the Engineering Specification Tree and opened
for edition. You can modify it to remove or add filter units and then insert it in a
specification.
Note:
The created part filter has been cloned from the original
one.
