道路平滑 / Road Smoother 1.0.1

平滑道路/桥梁高低起伏、坡度和转弯，平滑道路/桥梁高低起伏、坡度和转弯，使其看起来更自然美观。

【打开工具】在存档模组配置启用本模组并重新载入，点击左上方图层按钮旁的“RS”。悬停显示完整名称。

【选择道路】点击道路上的黄色节点选择起点、终点；也可点击道路端点附近。工具高亮两端间最短道路路径。走错路时使用“添加途经节点”，按行进顺序补选节点后结束添加。正常点击替换终点，“反向选择”交换两端，“重新选择”清空选区。节点拥挤时拉近镜头，注意桥上与桥下节点的区别。

【调整参数】先用默认参数查看预览。高度与坡度、转弯平滑可独立开关。最大坡度与横向位移是参考值，超出会提示。选完两端且路径含桥梁后才显示桥面项。水平桥面形成平顺主体；2% 缓坡按起终点方向设置坡度；对称坡道统一两侧引道；拱桥持续上升至中心高点再下降，无中间平台。

【桥面标高】数值是世界绝对高度，不是距地净高或相对抬升量；手动最大 50 米，步长 0.5 米。“自动”清空对应参数。过渡长度表示每端长度。拱桥模式的中心标高应高于两端，主体坡度/过渡长度暂停生效。实际路口高度保留，会分隔整形区间。

【应用与取消】等待预览更新，检查费用、桥墩、桥下净空和碰撞，再点“应用”。只选点或拖动滑块不会提交重建。Esc、右键或关闭窗口取消预览；已提交的建造命令不能用 Esc 撤回。可用“撤销上一次”恢复当前会话最近一次可完整恢复的成功操作；重新载入清除撤销。

【无法建造】查看原生消息，扩大选区给高差留出过渡空间、降低目标标高或恢复自动参数，并检查路口与桥下道路。部分选区仍无法满足游戏约束。强制模式仅在主动勾选后忽略游戏建造错误，不会修复碰撞或保证通行。附属设施或额外拆除可能使完整撤销不可用；建议先备份存档。

Road Smoother 1.0.1

Smooth roads/bridges with undulations, slopes, and turns make them appear more natural and aesthetically pleasing

Open: enable the mod for your save, reload, and click RS beside the map layers button at the top left.

Select: click yellow road nodes for the start and end. The shortest connected road path is highlighted. Add via nodes in travel order to guide the route; a normal click replaces the end. Reverse direction swaps endpoints; Select again clears them. Zoom in to distinguish elevated nodes from roads below.

Adjust: smooth height/grades, turns, or both. Grade/lateral-shift limits are advisory. Bridge settings appear only after a complete selection contains a bridge. Choose Level deck, Gentle 2% grade, Symmetric ramps, or Arch. Bridge center elevation is an absolute world height (manual maximum 50 m), not height above terrain. Automatic clears a parameter. Arch has one crest and no flat center deck; the crest should exceed both endpoints. Fixed junctions split profiles.

Apply: wait for the native preview and inspect cost, pillars, clearance and collisions, then Apply. Selecting nodes or changing settings does not construct anything. Esc, right-click or closing the window cancels preview; an already submitted command cannot be cancelled this way. Undo restores the last eligible operation in the current session; reloading clears undo.

Construction errors: check displayed messages, extend the selection for gentler transitions, lower target elevation or use automatic settings, and inspect junctions/roads below. Some selections remain unbuildable. Force mode ignores building errors but does not fix collisions or guarantee driveability. Attachments or collateral removals may prevent a complete undo. Back up your save first.
