The AutoCAD WS GPS function allows you position yourself within the design and use the built-in GPS functionality of your smartphone or tablet to track your location on the design. As you move around, you can add contextually relevant comments at precise geographic locations.

The AutoCAD WS GPS menu contains 3 options : Set Location, My Location and Settings.
Set Location
Some drawings may already contain geographic location data (using the Geo Marker object) and will not require you to set the location first. If your drawing does not contain this data, you can set it by tapping the “Set Location” button and picking the point on the drawing that you are currently standing at. The app will use the device’s GPS to determine the precise longitude, latitude and altitude coordinates of that point and will set that data to the drawing. You can manually adjust the x, y and z coordinates of the point you tapped if needed.
My Location
If your drawing already contains location data (whether by the Geo Marker object or by using the “Set Location” feature), you can use My Location to track yourself on top of the drawing. After turning on the “My Location” feature, you can move around and notice that the location marker is tracking your movement within the drawing. You can also take notes and comments at specific locations by using the “Mark” button.
Moving around the drawing
As you move around with the mobile device, your location marker in the drawing will change accordingly. Using the settings menu, you can set the north angle in the drawing, manually change the coordinates or define whether your drawing uses meters or feet to define one drawing unit. If the drawing units are set to meters for example and the north angle is set to zero, moving 30 meters west will move the location marker 30 X units to the left.
The AutoCAD WS GPS functionality is dependent on your mobile device and its GPS coordinates, you may need to enable the GPS function in order to get a more accurate information.To achieve maximum precision on some devices, it is recommended to turn on the device’s GPS for a minute or two and let it calibrate before using it.
