Project Location and Project North

from Options > Project Preferences > Project Location
from the Sun dialog box
Click Edit to modify these data by opening the Project Info dialog box.
Enter the Latitude and Longitude of the Project Location.
Altitude: Enter the altitude of the project location in the desired units. (Altitude data is used when you export the project to SketchUp and Google Earth formats. Altitude is also used as the Sea Level Reference Level for your project, at Options > Project Preferences > Reference Levels.)
Time Zone: Choose a time zone at the Project Location, expressed as a positive or negative offset from UTC (Coordinated Universal Time), together with the name of the corresponding time zone.
As a quick way to enter Location data, you can choose a predefined city: click Cities at the right side of the Project Location dialog box.
Note: To edit the list of predefined cities and associated data, go to Options > Element Attributes > Attribute Manager.
Note: However, for maximum accuracy, you should prefer precise latitude/longitude data for the location of your project, rather than a predefined city.
Provided you have an Internet connection: click on Show in Google Maps to view the project location as defined by your latitude/longitude data.
Note that the accuracy of these units depends on the accuracy set for Angle Unit in Options > Working Units.
Click Options > Project Preferences > Set Project North, or
When using surveyor’s units (Options > Project Preferences > Working Units), the North of the Coordinates Palette and the Tracker will be the same as the one set here.
Use the Import and Export buttons to manage the information displayed in this dialog box.
The XML format stores and reads longitude & latitude, angle display format, time zone, altitude & altitude unit, north direction and display format.
The Google Earth (.kmz) format stores longitude, latitude & altitude as a single place mark. The import function will also read longitude and latitude data from .kmz files containing a single place mark. The altitude will also be imported if it is expressed in absolute mode (not relative or clamped).
The SketchUp (.skp) format exports and imports longitude, latitude, altitude, North direction and time zone. The Site Address:-city and Site Address:-country data are exported but NOT imported).
