A mod for marking where empty space must be in blueprints that removes entities after the blueprint is super forced placed. Optionally automatically adds negative space around belts or fluid pipes.

Features include:

• A spawnable negative space entity that is placeable on the ground, but when placed from a blueprint deletes itself.
• Super force building a blueprint will remove any entity in the way of negative space.
• An option to automatically add negative space around belts when creating blueprints (also works for copy paste).
• Same as above, but for fluid pipes.
• Auto-generated negative space can optionally only remove belt and fluid pipes that would connect with belts or fluid pipes placed by the blueprint.
• Customizing the style and color of the graphic.

Experimental

This mod has not been extensively tested, so please report any issues.

Known issues:

• Some undo or redo actions involving a manually placed negative space (not blueprint placed negative space or auto-generated negative space) break the undo history.
