Bring the architect's drawing into the 3D scene so survey points sit in the context of the design. Overlays live in the Overlays tab of the project workspace.
DXF, not DWG
SiteLens imports DXF — the open, text-based CAD interchange format. It parses lines, polylines, arcs, circles, and layers and renders them as amber linework in the scene.
DWG (Autodesk's closed binary format) is not supported directly: there is no reliable open parser for it. Export your drawing to DXF from your CAD tool first. Uploads are limited to 10 MB.
Placing the drawing
A DXF carries no map projection, so you position it on the site with four controls, each saved with the overlay:
- Offset E / N — where the drawing's center sits in projected easting/northing.
- Rotation — spins the drawing about its own center.
- Scale — grows or shrinks the drawing about its center.
- Elevation — the flat height (Z) the drawing is drawn at.
Because rotation and scale both pivot about the drawing's center, changing one never slides the drawing off — the placement controls stay independent.
The quickest start is Auto-place at site: it fits the drawing's extent to your survey points' footprint and centers it on them, so you only fine-tune rotation, scale, and elevation from there. Auto-place ignores stray geometry (a title block or a lone point at the file origin) when sizing the drawing, so it keys off the actual floor plan.
Adjust the sliders (or type exact values), then click Apply georeference to save. The 3D scene refreshes with the new placement.
Flat reference plane
The drawing renders flat at its elevation — it is not draped onto the terrain surface, so it stays level on the X/Y plane. Use the Elevation control to lift or drop it to any Z: sit a floor plan at the building's floor level, or raise it above the terrain so it reads clearly as a reference.
Working with layers
DXF layers are preserved. In the viewer's Layers menu you choose which layers to show — none are shown by default, so you opt in only the layers you want (with a Select all / none shortcut). Your selection persists as you work.
Each overlay also has a Visible switch to show or hide the whole drawing at once.
That's the end of the guide — head back to the docs home for anything you want to revisit.
