Ensure your centerlines have smooth curves. Sharp 90-degree corners can cause overlapping geometry artifacts.
Creating realistic infrastructure on uneven terrain is one of the most frustrating challenges in 3D modeling. For years, architects, urban planners, and landscape designers have struggled with manually stitching roads, pathways, and highways onto complex topography.
: Creates road surfaces that follow terrain elevations or specified call-outs.
The plugin (often part of a suite like Instant Site Inspector or Instant Terrain ) is a tool for SketchUp (primarily versions 2017–2021, with some legacy support) designed to automate road creation on terrain.

If your work involves undulating topography, precise grading requirements, and detailed road cross-sections (curbs, medians, shoulders), Instant Road remains the superior choice. Its ability to adapt to any terrain elevation with customizable cut/fill slopes is unmatched by most competing tools.
What takes hours of terrain manipulation takes seconds with Instant Road.
The Instant Road plugin is a specialized extension designed for SketchUp, aimed at simplifying road design. Developed by a team of experts in transportation engineering and 3D modeling, Instant Road provides a comprehensive set of tools for creating realistic and accurate road models. With this plugin, users can generate roads with ease, taking into account various factors such as road type, width, and curvature.
Developed by Vali Architects, the Instant Road script is a specialized Ruby extension designed to eliminate manual road modeling. Unlike traditional methods that rely on SketchUp’s native “Follow Me” tool—which often results in broken geometry on uneven ground—this plugin projects geometry directly onto terrain.
