About Structural Views

Structural view is a view generated from structural (SDD/SFD) elements.

A structural view can be used in Classification drawings (drawings for classification society describing stiffening and how the ship is built) or Structural assembly drawings (drawings from detail design to assemble all the plates/profiles in the manufacturing hall) or Panel drawings.

Structural View Concepts

Structural view provides capabilities to generate the logical view by computing primary and secondary objects based on plane and spatial box.

Primary Object: The main part in the logical view.

Secondary Object: Structural object that intersects with the primary objects.

Isolated Object: The object in the view that is not a primary or a secondary object.

Structural View Sample



The 2D representation for the SFD or SDD parts is based on the GSV settings on the structural logical view.

For more information on GVS settings on the structural logical view, see 3D Modeling: Multi-Discipline Engineering: Structure Functional Design: Administration: Working with Drawing Production.

Primary Angle Computation

If a spatial filter box is created, all the panels that intersect with the spatial filter boxes and are parallel to the view plane with an angular tolerance specified by you are considered as primary objects.



In the above image, P1, P2, P3, P4 are panels. P3 has an angle of 20 deg with the view plane.

With spatial filter boxes is defined

If the angular tolerance for primary objects >= 20 deg, the computed primary objects are P1, P2, P3, and P4.

If the angular tolerance for primary objects < 20 deg, the computed primary objects are P1, P2, and P4. As P3 is an angle with the view plane higher than the input value of angular tolerance.

With no spatial filter boxes is defined

The primary objects are P1 and P2, because only these two panels have the same support as the view plane.

Secondary Angle Computation

During a view update, the angle between the secondary and primary objects is computed as follows:

If the angle is below the secondary angle tolerance value (orthogonal to primary objects), the default result specified in the tolerance for structure object is used.

If the angle is above the secondary angle tolerance value, the default result specified in the tolerance for structure object is used.

You can override the default result on a specific structure using the change object result command. For more information, see Modifying the 2D Result Corresponding to a Structural Object.

About the Default Structural Box

  • A structural box is created along the selected view plane up to the part end.
  • If you change the plane selection during structural view creation, the default structural view box is recomputed.

Notes: Default structural box is also a spatial filter box. It is used to filter the view objects during view update based on the filter type selected.
  • If the box filter type is All Intersected elements: All the view objects that are intersected with the spatial filter box are extracted in the drawing.
  • If the box filter type is Only inside the box: Only the view objects that are fully inside the spatial filter box are extracted in the drawing.
  • If the box filter type is 3D clipping: All intersected objects are clipped and all objects that are outside the box are not extracted.

You can create multiple spatial filter boxes. All boxes are used for computing primary objects and as a spatial filter. For more information, see Creating a View Filter.
