Learn how to specify the Georeference Settings of your Drawing
Georeferencing tells Plex-Earth Lite where your drawing is located on Earth. Without it, the software cannot place imagery, align satellite or aerial photos to your design, or calculate real-world coordinates. Georeferencing is required before using any Plex-Earth Lite feature — it is always the first step.
How to Access Georeference Settings
In the Plex-Earth Lite ribbon, go to the Project panel and click Assign Georeference. Alternatively, type PXV_GEO in the command line.
Choose a Georeferencing Method
Select the method that matches your situation:
| Method | Best for | Related Article |
|---|---|---|
| AutoCAD / BricsCAD native commands | Drawings already georeferenced using GEO, GEOLOCATION, MAPCASSIGN, or GEOCSASSIGN (AutoCAD, Civil 3D, Map 3D). Plex-Earth detects these automatically — no action needed. Click Assign Georeference to confirm: it will show By AutoCAD if detected. |
Choose a Coordinate System |
| By Coordinate System | New drawings, or drawings already based on a known coordinate system included in the Plex-Earth list. Supports search by country, system name, or EPSG code — over 3,000 systems available. | Choose a Coordinate System |
| By Geographic Location (Custom Georeference) | Existing drawings built on arbitrary or unknown coordinates. Lets you tie a point in your drawing to a known latitude/longitude or a Google Earth location — no coordinate system name required. | Apply Custom Georeference |
| Quickly Georeference a Blank Drawing | Blank drawings where you know the area of interest in Google Earth. Uses a Google Earth placemark to automatically define the georeference settings via a custom georeference. | Quickly Georeference a Blank Drawing |
