Before using any of Plex.Earth's functions, you must select an applicable coordinate system for the area of your project. This can be done in three ways:
1. Have you set a coordinate system your drawing's settings or defined it through AutoCAD's GEO command?
In this case Plex.Earth will read it directly (you can see this in "Select Zone & Units") and it will be used by all subsequent commands. If needed, you can also switch to any other coordinate system by directly selecting it from Plex.Earth's lists.
Note: This option is only available in AutoCAD 2015/2016 and verticals
2. Is you drawing based on a specific coordinate system, but this is not defined in AutoCAD?
If your AutoCAD drawing is based on a specific coordinate system, but this is not defined in AutoCAD (or if you are using AutoCAD 2014 or older) you can directly select it from Plex.Earth's "Select Zone & Units" lists.
Over 3000 coordinate systems worldwide are supported, and even if you can not find the one you are using you can contact us at support@plexscape.com (preferably with its definition or EPSG code) and we will try adding it.
3. Is your project not based on a specific coordinate system?
When the elements in your drawing are built on arbitrary coordinates -typically around (0,0)- you can still use Plex.Earth with it, by either:
- Using's AutoCAD's "GEO" command to manually georeference your drawing. Your selection will then automatically be used by Plex.Earth. (AutoCAD 2015-2016 and verticals only)
OR
- Following the procedure described in the tutorial below to roughly georeference your project from within Plex.Eearth:
