Displays the options that you use to place a design or planning seam in the model.

 Seam by Projection Properties

Opens the Seam Properties Dialog, which you use to view and modify the properties of the seam that you are about to place in the model.

 Plate System

Specifies the plate system for the seam. You can select multiple plate systems to place multiple seams at the same time. The software uses the same information for each seam. After placement, the seams are unrelated to each other and can be edited as individual entities.

 Define using 2D Sketcher

Defines the landing curve by drawing it in the Sketch 2D environment. See the Landing Curve Definition Controls section below.

Projection3D Landing Curve Definition by 3D

Allows creation of the seam curve directly in a graphic view by using the Seam Palette dialog (similar to the Geometric Construction Palette), the Geometric Constructions ribbon, and the Geometric Construction Explorer. This option is the 3D equivalent to Sketch 2D.

 Boundaries

Defines the boundaries of the seam. You can define the boundaries by selecting objects, including other seams, in the model. If you select objects in the model and those objects are moved, the software automatically resizes the seam to maintain the boundary relationship. See the Boundary Definition Controls section below.

Finish

Places the seam using the defined parameters.

Landing Curve Definition Controls

Available when you use the Define using 2D Sketcher  option.

 Sketching Plane

Specify the sketching plane for the curve. This is the first step in defining the curve. See the Define Plane Controls section below.

Add Intersecting Item

Select objects in the model that intersect the sketching plane that you want to use as reference geometry. These extra objects display in the Sketch 2D environment.

Add Projection Item

Select objects in the model that do not intersect the sketching plane that you want to use as reference geometry. These extra objects are projected onto the sketching plane and display in the Sketch 2D environment.

Constraint Table Constraint Table

Opens the Constraint Table dialog from which you can modify sketch curve constraint values without going back into the Sketch 2D environment. A sketch curve must have already been defined in Sketch 2D before this option is available.

Type

Displays the constraint type. You cannot edit the type.

Name

Displays the constraint name. You cannot edit the name.

Value

Defines the constraint value. Include the units of measurement when you edit the value: deg, mm, in, and so forth. You cannot edit a value if it is derived by a formula.

Value Type

Displays the value type: angle, radial, linear, and so forth. You cannot edit the value type.

Formula

Displays the formula used to derive the constraint value. You cannot edit formulas, nor can you edit values derived by formulas.

Layers

Filters which constraints display in the dialog based on the Sketch 2D layer to which they belong. By default, all constraints on all layers display.

Sketch 2D

Opens the Sketch 2D environment in which you can draw the curve.

To display a grid or reference plane ruler in the Sketch 2D environment, first define an active coordinate system using Tools > PinPoint Command.

Auto Import Enable/Disable

Allows the software to automatically add all objects that are relative to the object to be sketched to a select set. Items in the select set are highlighted in the graphics view and in the Workspace Explorer. If no objects are added to the select set, the software displays a message in the status bar. This option is only available when you use the Add Intersecting Item or the Add Project Item option. See Sketch 2D Best Practices.

Define Plane Controls

Available when you use the Define using 2D Sketcher option.

 Offset from Plane

Defines a plane at a specified offset distance from another plane. An offset distance of 0 defines a coincident plane.

 Plane by Point and Vector

Defines a plane using a vector normal to the plane being defined. A third point defines the plane position along the vector.

 Plane by Three Points

Defines a plane using three points that you identify in the model.

/Com_Unlock ICON Offset Lock

Locks the Offset value, disabling updates of the offset value by moving the pointer in a graphic view. The Lock option is only available when you use the Offset from a Plane method.

Offset

Specifies the offset distance from the selected grid plane or planar model object. You can specify the offset dynamically by moving the mouse in a graphic view or by typing the distance. This option is only available when you use the Offset from a Plane method. You can type the following formats for offset values:

  • Offset distance without units.

Example: 5, when default units are millimeters (mm). The software converts the distance to 5 mm.

  • Offset distance with units. The value converts to the default units.

Example: 5 m, when default units are millimeters (mm). The software converts the distance to 5000 mm.

  • Coordinate System: Frame plus or minus an offset distance.

Example (when the model has multiple coordinate systems): CS_0:F20 + 1.5 m

Example (when the model has one coordinate system): F20 + 1.5 m

/ Remove/Maintain Relationships of the Plane

Maintains the relationships of the plane to the definition method and the geometry used by the definition method. For example, a plane created with Offset from Plane  maintains the relationship of the selected plane and the Offset value. Otherwise, this option disables the relationships of the plane to allow moving of the plane.

When you copy a bracket and use Edit > Paste > Delete Optional to remove a boundary, Remove/Maintain Relationships of the Plane / is not visible. You must first click Select Bracket Supports to allow the command to determine the applicable options.

 Select Vector

Specifies a vector normal to the required plate system plane. This option is only available when you use the Plane by Point and Vector plane method.

 Define Point

Specifies the point along the vector at which to place the plate system. This option is only available when you use the Plane by Point and Vector plane method.

 Define Point 1

Specifies the location of the first of three points that defines the plane. This option is only available when you are using the Plane by Three Points plane method.

 Define Point 2

Specifies the location of the second of three points that defines the plane. This option is only available when you are using the Plane by Three Points plane method.

 Define Point 3

Specifies the location of the third of three points that defines the plane. This option is only available when you are using the Plane by Three Points plane method.

Boundary Definition Controls

Available when you use the Boundaries option.

 Pick Boundaries

Selects objects in the model or in the Workspace Explorer to define the boundaries. This option is only available when you are defining the boundaries.

 Solve Ambiguity

If the objects that you selected in the model for the boundary define an ambiguous solution, then the software prompts you to select one bounded section to clarify the needed boundary. This ambiguity only occurs if one of the boundaries wraps around both sides of the profile or seam, such as the hull. Move the cursor over a bounded section, and then click to select.

 Boundary List

Opens the Boundary List Dialog. This dialog box allows you to review and define the boundaries.

 Reject

Clears all selected objects.

 Accept

Accepts all selected objects.

Plate Split Delay

This option is available only when you modify a design seam.

Select this option to delay the split plate update to a more convenient time. The new position and boundaries of the design seam will appear in the graphic view when this option is selected. However, the plate being split is placed on the To Do List with the message Plate System split was stopped due to delay split with a status of Out of Date. You are responsible for going to the To Do List and updating the plate system at a later time. If you do not select this option, the plate is updated as soon as you move the design seam, which can take several minutes to process, but no To Do List item is created for the plate.

Seam Type

Specifies the type of seam to place. Select Design Seam or Planning Seam.
