Defines the coordinate system with which you want to associate the elevation planes, grid planes, radial planes, and radial cylinders. You create and modify these planes/cylinders later using the wizard. In addition to selecting existing coordinate systems, you can also create a new coordinate system to which you can assign the elevation planes, grid planes, radial planes, and radial cylinders. You then have the option of creating grid lines/arcs along the intersections with the elevation planes.

Name

Defines the name of the coordinate system that you are creating. This coordinate system name will display as the default reference coordinate system in the Create Elevation Planes, Create X-Planes, Create Y-Planes, Create Radial Cylinder, and Create Radial Planes dialog boxes in the Grid Wizard.

System

Select the parent system for the coordinate system that you are creating. The default value is the Configure Project Root. You can access other parent systems by clicking the More... option.

New Coordinate System

Assigns the elevation planes, grid planes, radial planes, and radial cylinders that you are creating to a new coordinate system with a north arrow and an origin that you define on this page.

Existing Coordinate System

Assigns the elevation planes, grid planes, radial planes, and radial cylinders that you are creating to an existing coordinate system.

Grid Type

Select the type of coordinate system to place. The Grid Type property cannot be modified on an existing coordinate system.

  • Grids - This coordinate system type uses East, North, and Elevation to define the three coordinate system axes. Naming rules for the elevation and grid plane names generally use E, N, and EL. The Z-axis (Elevation) is locked in the up direction. Grid lines are placed by default.

  • Ship - This coordinate system type uses X, Y, and Z to define the three coordinate system axes. Naming rules for the elevation (Z) and grid plane names generally use F, L, and D. Grid lines are not placed by default but can be placed if you want. The Z-axis is not fixed in any direction so the coordinate system can be rotated about the X- or Y-axis.

  • Coordinate System - Select Rectangular, Cylindrical, or Both to create a coordinate system with the following planes:

    • Rectangular - Elevation/Z-Planes, X-Planes, Y-Planes

    • Cylindrical - Elevation/Z-Planes, Radial Cylinder, Radial Planes

    • Both - All five types of planes.

Axis for Bearing

Select the X- or Y-axis as the axis to define the coordinate system North. This property is read-only for coordinate systems created using GridCSByPoints on the Coordinate Systems (Geometric Construction Palette Dialog Box) commands in Molded Forms.

Bearing

Specifies the bearing angle of the axis that you selected in the Axis for Bearing box. This bearing angle is defined with respect to the global coordinate system. This property is read-only for coordinate systems created using GridCSByPoints on the Coordinate Systems (Geometric Construction Palette Dialog Box) commands in Molded Forms.

Reference CS

Select the coordinate system in which to define the origin of the coordinate system that you are creating. The Reference CS property cannot be modified on an existing coordinate system.

East (X) / X

Specifies the easting or X coordinate of the coordinate system origin. If you are creating the coordinate system, you define this value with respect to the coordinate system that you selected in the Reference CS box. This property is read-only for coordinate systems created using GridCSByPoints on the Coordinate Systems (Geometric Construction Palette Dialog Box) commands in Molded Forms.

North (Y) / Y

Specifies the northing or Y coordinate of the coordinate system origin. If you are creating the coordinate system, you define this value with respect to the coordinate system that you selected in the Reference CS box. This property is read-only for coordinate systems created using GridCSByPoints on the Coordinate Systems (Geometric Construction Palette Dialog Box) commands in Molded Forms.

Up (Z) / Z

Specifies the elevation coordinate of the coordinate system origin. If you are creating the coordinate system, you define this value with respect to the coordinate system that you selected in the Reference CS box. This property is read-only for coordinate systems created using GridCSByPoints on the Coordinate Systems (Geometric Construction Palette Dialog Box) commands in Molded Forms.
