In the worlds of architecture, engineering, and GIS (Geographic Information Systems), two file formats reign supreme for very different purposes. The DWG (Drawing) format, native to AutoCAD, is the industry standard for precise 2D and 3D design data. The KMZ (Keyhole Markup Language Zipped) format, developed for Google Earth, is the go-to standard for geospatial visualization.
Before converting, always verify your DWG is georeferenced. If it’s not, the resulting KMZ will be just a floating set of lines on a blank Google Earth — a blueprint without a home. dwg to kmz converter online free
