The result was a catastrophe.
She dragged the KML into QGIS. Immediately, she saw the structure: a GeoPackage with layers named Panels , Cables , Exclusion . She right-clicked the Panels layer. Export → Save Features As.
“Hank, I have a DWG, but it’s exploded. Every panel is four lines.” open kml in autocad
“Of course,” she muttered. This was the ancient ritual. KML (Keyhole Markup Language) was born from the world of Earth browsers and GPS devices. DWG (Drawing) was born from the drafting board. They were two languages that had never learned to speak to one another.
The resulting DWG arrived by email. She opened it. It was… better. The scale was correct. The polygons were at the right coordinates. But now, a new horror emerged: Every polygon was no longer a single object. It was a collection of individual lines and arcs. The solar panel arrays—each a perfect rectangle in the KML—were now four separate lines. There were 5,000 panel arrays. That meant 20,000 individual line segments. The file size ballooned to 450 megabytes. AutoCAD began to lag. The result was a catastrophe
Perfection.
AutoCAD responded with the digital equivalent of a blank stare: "Invalid file type. Expected .dwg, .dxf, or .dwt." She right-clicked the Panels layer
“I can’t work with that,” Hank said. “I need closed polylines to calculate earthwork volumes. I’m not re-polygonizing five thousand rectangles. Try again.”
