Road Grid Builder

Build a whole road grid in one placement, then expand it with connected grids.

For anyone using the mod a quick fix to break the invisible anchors is to use the vegetation brush and just delete over the area for a little bit and it will break the invisible anchors. I am working on an update to resolve the issue.

Road Grid Builder adds an adjustable grid tool to Roads / Tools in Transport Fever 3. Choose the number of blocks, set their spacing, pick a road type and rotate the layout using the normal building rotation controls.

Features

• Adjustable layouts from 1 to 8 blocks across and deep.
• Independent block width and depth: 40, 60, 80, 100, 120 or 160 metres between road centres.
• Measurements automatically follow the game's metric or imperial setting.
• Small, medium and large town streets, plus small country roads.
• Follow Terrain to adapt road heights to the landscape.
• Smooth Terrain to shape roads and the ground inside the blocks into a smoother surface.
• Grid-to-grid snapping that reuses matching boundary roads, including corner gaps with multiple shared sides.
• Normal building rotation controls, including precision rotation.

How to use

1. Open Roads / Tools and select Road Grid Builder.
2. Choose the grid size, block spacing and road type.
3. Enable Follow Terrain and Smooth Terrain if desired.
4. To extend a grid, enable Grid snapping before building the first grid. Use matching spacing and road type, then move the next preview alongside an open boundary until it snaps into place.
5. Place the grid. Move the cursor slightly to prepare the next placement.

Good to know

• Snapping searches within 24 metres and accepts a rotation difference of up to 15 degrees. It recognises compatible grid boundaries, not arbitrary road layouts.
• With snapping enabled, terrain-following roads run directly between junctions. With smoothing off, small terrain variations between junctions are not followed individually.
• Smooth Terrain requires Follow Terrain. It shapes block interiors; outside banks use the game's normal road grading.
• Smoothing uneven ground can involve substantial earthworks. Required interior grading may prevent placement where the requested terrain shape conflicts with the surroundings.
• Changes apply to newly placed grids; existing grids do not update automatically.

Performance

Building large grids can be demanding on your PC, especially with terrain following and smoothing enabled. On lower-end PCs, build in smaller sections and snap them together instead of placing one large grid at once.

Future plans

• Better optimization and performance improvements.
• Support for modded road options.
• More features and quality-of-life improvements over time.

These are planned additions and are not included in version 1.0.
