Creating a Shell Expansion View

You can generate a shell expansion view by expanding the shell plate surfaces in the transverse direction. It is used for checking dimensions, topology, and structural integrity of the shell plates and also for verification of the seams, butts, and internal hull structure of the shell plating.

Before you begin:
  • Select Tools > Options > Mechanical > Drafting > Administration tab. Clear the Disable generative view style usage check box.
  • Set the ShellExpDrawingTemplate resource of the Structure Resource set in Project Resource Management.

  1. Open the structure system and draw a reference line in the X direction.

    The reference line should be a straight line parallel to the center line of the ship.



  2. Click Shell Expansion in the Operation toolbar.

    The Shell Expansion dialog box appears.

  3. In the Shell Plates box, select a shell plate.

  4. In the Reference box, select a reference line.

  5. Optional: In the Geometric Curve(s) box, select the curves on the shell plates.

  6. Optional: Set shell expansion options:

    1. Click Options...

      The Shell Expansion Options dialog box appears.

    2. In the GVS Template list, select a generative view style template.
    3. In the Select Plane of Symmetry box, select a plane.
    4. Select the Starboard or Portside option depending upon the selected shell plate.
    5. Click OK.

  7. Click OK in the Shell Expansion dialog box.

The progress bar appears indicating the shell expansion view generation. A new node is added in the specification tree indicating the generated shell expansion drawing of the structure system. You can double-click the drawing node to view the shell expansion drawing.

Notes:

  • Multi-selection of the shell panels is possible. However, the selected panels should lie only on any one side of the centerline i.e. starboard / portside.
  • Expansion of the shell panels is possible only on any one side of centerline i.e. the starboard side or portside.
  • Beams are excluded from the shell expansion drawing
  • Stiffeners limited by shell panels are not generated in the shell expansion drawing, for example, deck transverse stiffener limited by the shell panels.
  • You cannot update the shell expansion drawing. You need to create new drawing if any modifications are done.
