About
In 2009, our founder and CEO Lambros Kaliakatsos, a civil engineer and software developer, saw firsthand how much rework designing without real-world data costs. So he built Plex-Earth: the first cloud-based SaaS tool in the CAD market, connecting AutoCAD directly to Google Earth. It became the original AutoCAD + Google Earth plugin, and it changed how engineers work every day.
Today, Plex-Earth brings satellite and historical imagery, terrain, and two-way KML functionality into your drawing. From basemap providers like Google Maps, Google Elevations, Azure, and OpenStreetMap, and custom WMS/WMTS map connections, to premium providers such as Nearmap, Vexcel, Hexagon, Airbus, and Vantor, plus terrain data from GeoTIFFs and premium DTM/DSM sources, Plex-Earth is trusted by thousands of engineers across civil, solar, telecom, infrastructure, and beyond to design faster, smarter, and with real-world accuracy.
Compatible with AutoCAD 2020–2027, Civil 3D, Map 3D & BricsCAD.

About
Softree Optimal is an add‑on to RoadEng that reduces construction costs by optimizing both vertical and horizontal alignments. Its patented engine evaluates millions of design possibilities to deliver the lowest‑cost, standards‑compliant road design—often cutting vertical construction costs by 10–30% and achieving even greater savings when horizontal optimization is included.
With the addition of Path Explorer AI, the system now goes beyond alignment refinement to automatically discover entirely new corridor alternatives. It analyzes terrain, constraints, and cost factors to generate and rank multiple feasible routes, giving engineers rapid early‑stage insight and a stronger foundation for detailed optimization.
