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.
Fully Included in LizArk Main Plugin
You do not need to buy LizArk Roads Pro separately! It is 100% included under the LizArk main plugin (including the LizArk Basic license). Note: A standalone plugin edition will also be available in the near future for single-tool users.

- 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.

FAQ
Common Questions
Is LizArk Roads Pro included under the LizArk main plugin?
Yes, 100%! LizArk Roads Pro is fully included under the LizArk main plugin (including LizArk Basic, Pro, and Studio). You do not need to purchase a separate license.
Do I need to buy LizArk Roads Pro separately?
No separate purchase is required. We understand that having a separate buy button can cause confusion! LizArk Roads Pro is bundled directly inside the LizArk main plugin. In the near future, LizArk Roads Pro will also be released as an independent standalone plugin for users who only want road design, but LizArk main plugin licenses already get full access included today.
Does LizArk Basic include LizArk Roads Pro?
Yes, absolutely! LizArk Basic ($39/year) comes complete with LizArk Roads Pro (road corridors, junctions, roundabouts, kerbs, signs, and CSV export) as well as LizArk Rail.
When will LizArk Roads Pro be available as a standalone plugin?
A standalone plugin edition is planned for release in the near future for specialists who only need road and junction automation without the full architectural building suite.
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.
