Build Gun

The Construction Tool is a placeholder name for a tool engineers can use to place and dismantle buildings. It projects a hologram showing where the build-able structure will be placed, and highlighting key features such as belt inputs, outputs and power sockets. Thick teal lines will be drawn if two buildings are aligned together. It is also the same tool that does resource scanning. The engineer will equip the tool before exiting the drop-pod. The tool is not craft-able and will still be equipped even after the engineer respawns or dies.

Build menu
The build menu is opened with the key by default. Here all the buildings the engineer has unlocked are sorted into tabs. Left-clicking a building will exit the menu and display a hologram version of the building. The engineer can then position it where they want and then left-click again to build.

Buildings can also be added to the To Do List from the build menu.

Dismantling
The construction tool can be brought out in dismantle mode by pressing the key by default. Buildings that the player's cursor is over will be highlighted, and can then be deconstructed by holding down left-click. An orange border will appear around the screen to indicate that dismantle mode is on.

Technical details
Placement and deconstruction range is 100 meters (12.5 foundation lengths). Buildings can be rotated with by default, in increments of 10°, or 90° when placed on foundations.

Mass building
There are currently no systems in the game equivalent to blueprints (from Factorio) allowing for building multiple structures together. A blueprint system may be added post alpha.

Emote
Pressing the emote wheel and select 'twirl it' will display an animation showing engineer twirling the construction tool.

Trivia

 * When exiting the drop pod at the start of the game, the engineer fastens a partly loose sticker on the Construction Tool/Resource Scanner. The sticker is a picture of Box Boy from Coffee Stain Studios' very first game, I Love Strawberries, released in 2010.
 * The Construction Tool has numerous lines of text printed on its casing.
