Plex-Earth
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.
