XYZ Coordinates

XYZ coordinates are typically used with marine projects. The example displays From and To limits which can be used to include elements within specified position values.

The ship coordinates can be defined using X, Y and Z directions. Positive and negative position values can be used.

Positioning with Respect to Grid

Reference grid coordinates can be used with plant and marine projects.

Select from the Reference grid drop-down list to define the grid from which the coordinates are derived.

Use Grid Format on Positioning Forms

Select the check box to display positioning windows with coordinates derived from the selected reference grid.

Display Positions in Grid Coordinates

Select the check box to display positions across the application, including the coordinates fields in positioning windows, with position values measured from the nearest grid.

The example displays a referenced plant grid with From and To limits which can be used to include elements within specified position values.

The plant grid coordinates can be defined using Axis, Row and Elevation directions (the Axis, Row and Elevation labels may be different as they are populated from the GRIDFA and GRIDLBL attributes of the reference grid). Positive and negative values can be used.

The example displays a referenced ship grid with From and To limits which can be used to include elements within specified position values.

The ship grid coordinates can be defined using Frame Positions and Longitudinal Positions. (the Frame Position and Longitudinal Position labels may be different as they are populated from the GRIDFA and GRIDLBL attributes of the reference grid). Positive and negative values can be used.

Display Positions as Absolute Values

Click to populate the coordinates fields with absolute position values measured using the current coordinates system.

Display Positions as Offset from Nearest Grid Plane

Click to populate the coordinates fields with position values measured from the nearest grid plane.

Pick Position

Click to populate the coordinates fields with position values measured from a picked position in the 3D view.

Offset

Click Offset to modify the position of the coordinates by an offset measured from the original position. Click Return from offset mode to exit the offset display.

Lock

Click to lock the coordinates in a specified field; the position values cannot be modified. Click again to unlock the field.

WRT

The With Respect To (WRT) field can be used to define an element from which the coordinates are derived.

The name of the required element can be modified explicitly; other options are also available:
