Marine mode orientation rules specify the available orientations for the current view type. You specify the orientation rule used with a layout style when you use Place View in a drawing document open in SmartSketch Drawing Editor or on the General tab of the Setup dialog box in the Drawings and Reports task. For more information on using orientation rules, see the Orthographic Drawings User's Guide.
The orientation rules are delivered on the client machine in the [Program Folder]\ShipDrawings\Middle\Bin folder. The rules are also bulkloaded into the catalog. For more information, see OrientationRule Sheet.
Global Coordinate System (ISGlobalLCS.Default)
Orientation is relative to the global coordinate system. View direction options include planar view options such as Looking Aft or Looking Port; and isometric view options such as Up Port Aft and Plan Starboard Forward. Up direction options are dependent on the selected view direction and include planar view options Plan, Up, Aft, Forward, Port, or Starboard; and isometric view options Up, Down, Left, or Right.
Local Coordinate System
Orientation is relative to the local coordinate system of the part as defined by the software. View direction options include planar view options such as Right (Along -X) or Top (Along +Z), and isometric view options such as Top Front Right and Bottom Back Left. Up direction options are dependent on the selected view direction and include planar view options along the X-, Y-, and Z-axes in both directions, and isometric view options Bottom, Top, Back, or Front.
Not Applicable (SMNotApplicableLCS.Default)
Orientation rule has no significance. Both View direction and Up direction options are Not Applicable.
Mfg PinJig SideView (SMMfgPinJigSideLCS.Default)
Orientation is relative to PinJig local coordinate system. View direction options
include planar view options such as Left (Along +X) or Right (Along -X). The up direction option includes Jig Floor Up.
The up direction is along the jig floor and view directions are along +X and -X, as shown below:
Scantlings for Plate/Profile
Orientation is relative to a view direction that is across the local x-, y-, and z - axes of the view coordinate system. If the view does not have any coordinate system, the view direction will be set to the global X-, Y- or Z-axis. The following are standard combinations of view direction and up direction:
Transverse Bulkheads
Section view Looking Aft: View direction is looking aft (Along -Z), Up direction is up (Along +Y).
Section View Looking Fwd: View direction is looking forward (Along +Z), Up direction is up (Along +Y).
Longitudinal Bulkheads
Elevation Looking Stbd: View direction is looking starboard (Along -Z), Up direction is up (Along +Y).
Elevation Looking Port: View direction is looking port (Along +Z), Up direction is up (Along +Y).
Decks
Plan Looking Down: View direction is looking down (Along -Z), Up direction is port (Along +Y). The forward end of the ship is always oriented to the right of the drawing.
Shell Profiles
View direction will be either Global –Z or Global +Y based on the angle between the web surface of the shell profile and Global –Z axis as shown below:
The orientation rule sets the view direction to:
Global -Z (Plan looking Down) if the angle of inclination is less than the tolerance angle.
Global +Y (Looking Port) if the angle of inclination is more than the tolerance angle.
The default value for the tolerance angle is set to 75 degrees. You can configure the tolerance angle value using the Angle for Target Evaluation (Optional) view query in the view style. See Steel Order Drawing Rule Set.
Mfg Template At Index
Orientation is relative to the local coordinate system of a template within a template set. The template is identified by its index number within the template set. View direction options include planar view options such as Right (Along -X) or Top (Along +Z), and isometric view options such as Top Front Right and Bottom Back Left. Up direction options are dependent on the selected view direction and include planar view options along the X-, Y-, and Z-axes in both directions, and isometric view options Bottom, Top, Back, or Front.
Shell Expansion for Plate
Used for partial shell plate expansions and expansion of curved and knuckled internal plates. Orientation is relative to the global coordinate system. Up direction option is Up. View direction options are as follows:
Looking Outboard and Looking Inboard
Looking Port and Looking Starboard
Expansion (Hull)
Used for full shell expansions. Orientation is relative to the global coordinate system. In all view directions, hidden line conventions are ignored. The hull plate is always solid, and all connected plates and profiles are dashed. The up direction option is Up. View direction options are as follows:
Centerline Looking Port and Starboard Looking Centerline - Forward is to the right in the view.
Centerline Looking Starboard and Port Looking Centerline - Forward is to the left in the view.
View Coordinate System
Orientation is relative to the coordinate system specified in the view definition. View direction options include planar view options, such as Right (Along -X) or Top (Along +Z), and isometric view options, such as Top Front Right and Bottom Back Left. Up direction options are dependent on the selected view direction and include planar view options along the X-, Y-, and Z-axes in both directions, and isometric view options Bottom, Top, Back, or Front.
If the View direction does not have any coordinate system, then it will be set to the global X-, Y- or Z-axis.
Scantling By Plate Normal
Orientation is relative to plate normal. The following are standard combinations of view direction and up direction:
Plate normal inclined towards global X-axis
Looking Aft: View direction is looking aft along the plate normal (Along –Z), Up direction is up (Along +Y).
Looking Forward: View direction is looking forward (Along +Z), Up direction is up (Along +Y).
Plate normal inclined towards global Y-axis
Looking Stbd: View direction is looking starboard along the plate normal (Along –Z), Up direction is up (Along +Y).
Looking Port: View direction is looking port (Along +Z), Up direction is up (Along +Y).
Plate normal inclined towards global Z-axis
Plan Looking Down: View direction is looking down (Along –Z), Up direction is port (Along +Y).
Custom
Uses the current 3D graphic view as the orientation of the view when you use the Capture option of the Associate Objects to View Command.
