Align shutters with panels and partitions

Adjust per-edge reductions so shutters sit flush or leave a partition uncovered.

1. A shutter's default reduction is commonly 1.5 mm per side, so a 616.5 mm opening yields a 616.5 mm panel with 1.5 mm taken off each edge (3 mm total across both sides).

2. The default reduction is commonly 1.5 mm per side, though 1 mm reductions are also used.

3. Setting the top reduction to zero makes the shutter align flush with the end panel instead of sitting inset.

5. Setting both the top and bottom reduction values to zero leaves the shutter at its full height, with no reduction on either edge; the same zero values can be applied to a corner unit by editing that unit's key structure.

6. To stop a shutter from covering a partition, select the parent partition, add the shutter system, select the shutter, open the Construction tab and enter a reduction equal to the width of the partition that should stay uncovered.
