Placing buildings

  1. Hover over a tab denoting facility dimensions.

Buildings can be deleted by clicking anywhere on them on the map.

Keyboard Shortcuts

  • Keyboard shortcuts can be used when hovering over the map.
  • C: Construct/places the selected building.
  • F: Fetch - when hovering over a building already on the map, "fetches/grabs" the facility type off the map.
  • D: Deletes the building that the cursor is currently hovering over.
  • R: Rotates the currently selected facility type before placing it on the map.


Various enhancements to previous City Designer concepts were envisioned when this City Designer was developed, below is a concise summary of the newly implemented features.

  • Checks for restrictions on facilities based upon Terrain and Hidden-status of the city.
  • Does not allow the placement of facilities that violate the 2-sides rule, when the box is checked.
  • Enforces no overlapping of buildings.
  • Implicit Validation on-design-load for all of the above, as well as explicitly via the validate link.
  • Automatic stat calculation, such as employment rate (ER).
  • Shows the number of freighter hauls required to build the city (based on the Mass/Volume of the required raw materials and Mass/Volume capacity of the ship type).
  • Comprehensive error detection in city design input codes.
  • Has a confirmation box for clearing the map, instead of a double-click.
  • Does not allow the conversion of empty squares to roads.
