Google Earth Civil Topo CAD

I will send you a Google Earth Pro KMZ/KML along with a few reference screenshots. From that data I need a fully geo-referenced AutoCAD DWG focused on civil engineering land-grading and topography only—no roads or drainage at this stage.

The drawing has to:
• use the same coordinate system shown in the KMZ so it drops straight into our existing survey files
• convert all visible terrain into clean 1 m (or tighter) contour polylines on a dedicated “TOPO” layer
• include a separate surface or 3D-face mesh that I can run cut-and-fill volumes against
• keep spot elevations, major breaklines and any notable site features (tree line, building corners) on logically named layers

Acceptance criteria
1. When I XREF the DWG into Civil 3D at 1:1, the contours align with the Google Earth imagery within ±0.5 m horizontally and ±0.3 m vertically.
2. Layer names and colours follow the simple scheme I will attach (TOPO-*, SPOT-ELEV, BREAKLINE).
3. File opens cleanly with no proxy object prompts in AutoCAD 2020-2024.

Send back the finished DWG plus a PDF plot for quick review. If anything is unclear, let me know before you start so we don’t lose accuracy.
