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.

Alternatively, download the .rbz file from an authorized source and use Window > Extension Manager > Install Extension to install it manually. Basic Workflow for Creating Roads

Includes dedicated settings to simulate realistic riverbeds, streams, and drainage ditches.

Select both your centerline and the terrain group, then open the Instant Road dialog box. Here, you can customize: Road width Shoulder width and angle Curb height Transition smoothness Step 4: Generate Developed by Vali Architects, the Instant Road script

Obtain the standard .rbz file from the official developer or authorized extension marketplace.

The core utility of the Instant Road Pro lies in its ability to "drape" roads over curved terrain. Users can define crucial parameters such as road width, shoulder width (verge), curb presence (路牙), and subgrade fill height. It supports both Metric and Imperial systems, ensuring compatibility with international projects. Basic Workflow for Creating Roads user wants a

Unlike native SketchUp tools, which require complex operations to "drape" shapes over a surface, Instant Road intelligently interprets the terrain and cuts or fills the road profile to match.

Instead of manually drafting road geometry and stamping it onto terrain, Instant Road allows users to input simple lines or faces—and the plugin handles the rest. It produces clean, manifold geometry complete with shoulders, curb details, roadbeds, and supporting base layers.

: You can generate roads using either a single line (centerline path) or from pre-drawn faces (road outlines).

Using the standard SketchUp or Arc tool, draw the path of your road right above or directly on the terrain. This acts as the vector spine for the extension. Step 3: Configure Your Settings
