1 · Start a plan — select the planet and City Rank. Place a City Hall first; it is fixed at the exact centre and unlocks the remaining structure categories. The circular area is the real construction limit and each grid unit represents 8 metres.

2 · Add structures — choose MAYOR, RESIDENTIAL, PUBLIC, COM-IND or SPECIALS, select a structure and click the grid to place it. The catalogue automatically filters structures by planet, minimum Rank and quantity limits.

3 · Edit the layout — select a placed structure to open its action bar. Drag to move it; use Rotate, Duplicate, Distance, Focus, Info or Delete as needed. Press R to rotate the selected structure and Delete/Backspace to remove it. Fixed or non-rotatable structures keep their restrictions.

Validation & limits — structures must remain completely inside the city circle and cannot overlap. Rank, planet, rotation and quantity rules also apply. Invalid items appear in red; click the Issues indicator to review and focus each problem. A plan may contain only one City Hall and one Shuttleport, while Trainer and Terminal limits depend on Rank.

Rank & specialization — changing Rank resizes the city while preserving structure positions relative to City Hall whenever possible. A specialization can be saved with the plan; fixed specialization costs and structure maintenance are included in Weekly cost.

Coordinates — enter the City Hall coordinates in the displayed order Y, then X. The Coordinates tool calculates every structure's absolute SWG position from its offset to City Hall. Hover information also shows the distance to the centre.

Measure & sectors — Measure calculates the distance between two selected points. Sectors lets you drag a named rectangular zone over the plan; select a sector and use Delete sector, Delete/Backspace or double-click to remove it. Sectors are saved with the layout.

Map background — a plan opened from Planet Map can include the selected terrain capture and its restrictions. Blue areas are water, amber areas are slope warnings and purple areas contain both; structures cannot be placed over them. Show background / Hide background toggles the terrain in both 2D and 3D without deleting it.

3D View — switch to 3D to inspect the current layout in perspective. In Orbit mode, drag to rotate, use the wheel to zoom, right-drag or Shift-drag to pan and double-click to reset. You can drag movable buildings in 3D; changes are synchronized with 2D and follow the same placement rules.

Walk & Fly — Walk keeps the camera near ground level; Fly allows free movement. Use WASD or the arrow keys and drag to look around. In Fly mode, Space rises, Ctrl descends and Shift increases speed. Fullscreen keeps the current camera and navigation mode.

3D terrain — when the plan comes from Planet Map, the exact captured texture, restrictions and local relief are reproduced around City Hall. Hiding Background switches to the generic planet terrain. Environmental objects are visual aids only and are not saved as city structures.

Save & autosave — saving requires exactly one City Hall and a Nexus account with saving access. REGISTERED accounts can keep 1 plan and AUTHORIZED accounts up to 5. Local autosave can restore an interrupted unsaved draft; a successful Save clears that draft.

Public, private & shared plans — choose Public to list a plan in Community Plans or Private to keep it hidden. Share creates normal and clean Preview links; Preview and plans owned by another user are read-only.

Publish to Planet Map — save all changes, choose Publish to Map and select the real player city represented by the plan. Its authoritative City Hall coordinates are loaded automatically. The transparent, correctly scaled layout then appears in the City Plans layer of Planet Maps.

Update or remove a publication — after editing, save and publish again to refresh the map overlay. Remove from Map withdraws only the overlay and does not delete the plan. If the city's Mayor changes, the existing publication expires until an authorized Mayor republishes it.

Export — Export PNG creates the complete 2D plan regardless of the current zoom. In 3D mode, Screenshot captures the current camera and Export 3D creates a GLB from the visible terrain, structures, sectors and decorative objects.

Unsaved changes — adding, moving, rotating or deleting structures, changing city settings or editing sectors marks the plan as changed. New Plan and page navigation request confirmation before discarding pending work.
