The following procedure shows how the Spherical Coordinates 
option is used with the Tools > PinPoint command. For information on using rectangular coordinates or cylindrical coordinates,
see Place objects using rectangular coordinates and Place objects using cylindrical coordinates.
-
Select a task that allows you to place objects.
-
Click any Place <object name> command.
-
Select an object, and then specify the necessary properties.
The software displays the computed graphics of the selected object.
-
Click PinPoint
to display the PinPoint Ribbon.
Click Display On/Off 
to turn the PinPoint display on and off. You can also press F9 to toggle the PinPoint display on and off.
-
In the Coordinate System box, select a coordinate system in the list as the reference point.
Global - Global coordinate system is the default option. You cannot modify a global coordinate system.
Select Graphically - Allows you to specify a coordinate system graphically in the active window. Follow the instructions that appear in the status bar.
More - Displays the Select Coordinate System Dialog Box. Select a coordinate system from the Workspace or Database.
-
After you select an active coordinate system, click Set Target to Origin
(plant) or 
(ship).
The software considers the targeted position as the new origin from which the distance
will be measured. The target position does not change when you change the active coordinate
system.
-
Click Spherical Coordinates
.
The spherical value settings display on the right side of the ribbon.
-
Set the Distance value, and then click Lock/Unlock Absolute Distance
to lock the value. Absolute distance is the distance between the target and the pointer
location.
The shortcut key to lock/unlock this value is F6.
When you lock the Distance value, the software automatically locks the Vertical angle with a default value. You cannot unlock an angle while the absolute distance is locked and no other angle
is locked.
-
Set the Horizontal angle, and then click Lock/Unlock Absolute Distance
to lock the value. This angle is in the horizontal plane and is measured clockwise
from the N-axis (plant) or Y-axis (ship).
The shortcut key to lock/unlock this value is F7.
-
If necessary, set the Vertical angle. Click Lock/Unlock Absolute Distance
to unlock the value, and then lock after specifying a new value. This angle is measured
counter-clockwise from horizontal plane.
The shortcut key to lock/unlock this value is F8.
-
Click in the graphic view to place the object at the pin-pointed location.
The software places the object at the pin-pointed location.
-
The PinPoint command uses the highlight and selected element colors. You can set these colors on the Tools > Options dialog box. For more information, see Change a default color.
