Figure 5-61 Filter Matrices
2) Deselect any matrices that you do not wish to be visible in the Palette.
3) Select Apply. You return to the Palette.
Note: Deselecting a matrix does not remove it from the project.
Note: Entities from filtered out matrices do not show on screens for non-filtered frames. For
example, if you filter matrix 2, then go to, say the fixed groups screen on matrix 1, you do
not see any entities from matrix 2. This is only true for entities that are available to be
assigned - you always see already assigned entities (existing group members) whether
they are filtered or not. In addition, panel programming maintains a separate list of filters.
