Fence Placement Helper is a gameplay mod for Farming Simulator 25 that adds precision tools to vanilla fence building. It displays the live heading of the fence in degrees and draws a white straight-line reference guide with visible section markers while you place segments. The guide can snap to an existing or parallel fence, and optional snapping lets you lock new sections directly onto the straight-line guide to eliminate wobble.

Three guide modes are available. World 0°/90° (default) aligns fences to the nearest cardinal heading (0/90/180/270°); World 45° mode expands this to every 45° increment; Local mode follows an existing fence's angle or locks to a heading you choose. The mod also shows live deviation and lateral drift from the local reference. At a new connected corner in Local mode, you can automatically choose between a straight continuation or an exact 90° left/right turn.

Placement speed is handled by optional automatic long sections: OFF, 10 m, 25 m, 50 m, or 100 m, with 25 m as the default. Sections stay visually continuous thanks to the game's suppression of duplicate shared posts. Each section remains a native FS25 fence segment, so the standard demolition tool can remove them one at a time.

The mod uses the game's normal fence network events, savegame format, and server authority, making it fully multiplayer and dedicated-server compatible. It also works with customizable husbandry meadow fences, preserving the required native connection points and husbandry validation. Vanilla snapping and all existing construction buttons remain unchanged.

Controls: Left Alt + B cycles the section size, Left Alt + R re-locks the guide to the current fence angle, Left Alt + S toggles snapping to the white guide, Left Alt + G switches guide modes, and Left Alt + H is a master ON/OFF switch that instantly restores vanilla fence placement while keeping your helper settings.
