Road Networks
in SketchUp
Fully Parametric.
Generate road corridors, kerbs, footpaths, lane markings, zebra crossings, signs, junctions, roundabouts, and cul-de-sacs directly inside SketchUp from paths, CAD lines, or CSV data.
Feature Catalog
Everything you need for site roads
Draw & Import Roads
Create roads from scratch or convert existing paths and CSV files into corridors.
- Draw Road: Click start point, add points, and finish. Snap to existing road ends, hold Shift for straight segments, and toggle arc mode with Tab.
- Draw Curve Road: Place a 3-point arc road with start, through, and end picks.
- Generate from Path / CAD: Turn SketchUp edges, CAD layer lines, or imported geometry into roads.
- Generate from CSV: Load X,Y,Z point files to build corridors automatically.
- Live Preview: See carriageway, kerbs, footpaths, and markings update as you draw.
Corridor Components
Build every part of a real-world road corridor parametrically.
- Carriageway: 1-4+ lanes with configurable lane width, road thickness, texture scale and seamless geometry.
- Kerbs: Enable per side, set width, height, primary/secondary colors, dropped kerbs at ends.
- Footpaths: Tiled pavers, herringbone brick, slabs, concrete or asphalt; cycle-lane and tactile paving at crossings.
- Median: Raised center median with width and height controls.
- Lane Markings: Dashed, solid, and double lines with dash/gap/width controls plus stop lines.
Intersections, Roundabouts & Terminals
Automatically generate junction geometry or place standalone intersection elements.
- Intersection Generator: Click two crossing roads or auto-generate every detected crossing.
- Roundabout Generator: Drag a center radius and build islands, kerbs, lane markings, and entry/exit legs.
- Cul-de-sac / Terminus: Place circular bulbs or hammerhead T turns at road ends.
- Zebra Crossings: Draw configurable crossings with stripe width/gap and border colors.
- Signs: Place stock signs or build custom sign boards.
Manage & Export
Review, reshape, and report your road network.
- Edit Selected Road: Re-apply current settings to a selected XRP road.
- Edit Road Nodes: Drag centerline nodes to reshape any corridor.
- Dashboard: Floating panel with road length, lanes, footpaths and total network length.
- Export CSV: Quantity report with centerline length, road area, footpath area, and lane counts.
- Export DXF: AutoCAD R12 centerline output in meters.
FAQ
Common Questions
What is LizArk Roads Pro?
LizArk Roads Pro is a professional road-design extension for SketchUp. It generates corridors, kerbs, footpaths, markings, junctions, roundabouts, and signs from drawn paths or imported data.
Can I import CAD lines as roads?
Yes. Select edges or CAD-layer geometry, or load a CSV of X,Y,Z points, and choose centerline or edge generation mode.
Does it handle roundabouts and cul-de-sacs?
Yes. The Roundabout Generator builds islands, kerbs, and markings, and the Terminus tool places circular bulbs or hammerhead turns.
Can I export quantities?
Yes. LizArk Roads Pro exports a CSV quantity report and an AutoCAD R12 DXF centerline file.
