To move the project base point or survey point in a view, do one of the following:
■ Drag the point to the desired position.
■ Click the point and then click the desired coordinate to open the text box. Enter the new coordinates.For

NOTE changing the value of the Angle to True North is another way of rotating a project to true north. See
Rotating a View to True North on page 449.
The startup location is the original position of the project base point in a new project. To return the project
base point to its startup location:
1 Unclip the project base point.
2 Right-click the project base point, and click Move to Startup Location.
Pinning Project Base Points and Survey Points
You cannot move a pinned project base point or survey point. Pinning the project base point disables the
Relocate Project and the Rotate Project North tools. Pinning the survey point disables the Rotate True North,
Acquire Coordinates, and Specify Coordinates tools. See
Preventing Elements from Moving on page 382.
Tips for Working with Project Base Points and Survey Points
Consider the following when working with project base points and survey points:
■ To ensure accuracy of the model, be sure the model geometry is less than 1 mile from the startup location
of the project base point. To check this measurement:
1 Use Move to Startup Location from the shortcut menu to move the project base point back to its
startup location.
2 Use the Measure tool on the Modify tab to measure the distance from the project base point to the
model geometry.
3 If the distance is more than 1 mile, move the model geometry within 1 mile of the startup location
of the project base point.
