Plex Earth 4 is not cheap. A single perpetual license is around $500-$700, and the subscription model (which includes updates and LiDAR module) is roughly $300/year. For a freelancer or small firm, that’s a real investment. The free trial is generous (30 days, fully featured), but after that, the cost may push you toward free alternatives like QGIS (though that means leaving CAD behind).

Plex’s famous “skip intro” feature has been repurposed. If you’re viewing a time series, Plex Earth 4 marks significant change events (e.g., fire scars, flood extent, construction start) as “chapters.” You can skip directly to the moment a river changed course.

I tested PE4 on a 40-acre residential development site. After setting my coordinate system (State Plane), I inserted a Bing satellite basemap, overlaid a USGS DEM, and generated 2-foot contours. Total time: 8 minutes. In native AutoCAD, that would have been an hour of manual tracing and guesswork. I then imported a shapefile of wetlands from the state’s GIS portal, ran a simple query to find all areas within 50 feet of a stream, and flagged them as no-build zones. The workflow felt like a unified toolbox, not two programs fighting each other.
