Is there an existing issue for this feature request?

I have searched the existing issues

Great project ; credit where it’s due. OrcaSlicer has been a fantastic tool and I appreciate all the work that goes into it.

Currently, as of my knowledge OrcaSlicer only supports defining a 2D exclude area on the build plate.
This is useful, but limited when the user has hardware or interface blocks located higher up in the build volume.
Example: a filament cutter or tool block mounted in the top-right corner at coordinates like X10 Y200 Z200.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

Allow users to define a 3D cuboid (or region) as an exclude area within the build volume.
Orca should prevent toolpaths from being generated within this region.
Ideally, the 3D exclude zone could be visualized in the preview to make positioning clearer.

Describe alternatives you've considered

Using only a 2D exclude area — but this doesn’t protect against collisions when hardware is above the bed.
Manually splitting the model — inconvenient and error-prone.

Additional context

Such a feature would help users avoid collisions with mounted accessories or mods that occupy part of the build space (e.g., cutters, tool docks, camera arms), while still allowing full use of the safe regions of the build volume.
