Change partition dimension instead of translating a shelf

Adjust a cabinet by manipulating partition levels, add a shutter system at the partition level, and avoid translating a shelf so the shelf still matches the partition layout.

1. To adjust a cabinet, manipulate the partition levels, switch to fixed height, and use the add-drawer function to insert a drawer set.

2. Add a shutter system at the partition level.

3. Do not translate a shelf: translating it leaves the cam in place while the partition's section sizes stay the same, so the shelf no longer matches the partition layout.
