Central Anchor Points
These are useful when placing a latch that you want to keep central to a section of the case, or keeping a dish central to a panel.
If placing a latch...
If placing a handle, dish or fixing...
Note:
If you place a piece of hardware directly on top of a central anchor point, that part will always stay central to the panel or section of case.
However if you move the part away from this point, it will always maintain it's distance from the anchor if you change the case size.
Central Edge Anchors
If you are placing a handle or dish and select this anchor point, the part will simply maintain its exact position away from the chosen anchor.
In the case of an edge handle, by selecting the middle/central edge anchor the handle will always stay locked to that anchor point. As long as you don't move the handle from it's default position. (shown above)
