Data Orientation
More often the not, the roads and pads of a job site do not run exactly
North-South and East-West. Earthwork 4D can enter data by temporarily
changing the coordinate system based on a line segment that runs parallel
to the data to be entered. Any data lines drawn subsequently will follow
this new coordinate system. Below are the steps to entering data lines
in the same coordinate system as the existing data when the Status
Bar Display is set to Discreet Distance/Angle.
|
Place the
arrow over a line that is parallel to the data that will be entered. |
|
Press the
F12 Key on the keyboard.
The line displays a yellow diamond at each end. The job is now
setup to use these coordinates for data entry. |
|
Select
Discreet Distance/Angle
from the Status Bar Display submenu under the Options menu. |
|
Move the
crosshair to the first point of the line and press the Left Mouse
button. |
|
Move the
crosshair away from the first point and enter the next point.
You will notice how the angle snaps to new coordinate system.
Subsequent points are entered at 45°
increments. |
Pressing the X key on the keyboard
resets the program to the original coordinate system.
