Creating a Break on a Plate

This task explains the creating of a break on a plate.


1. With your document open, click the Split Plate button . The Split Plate dialog box opens. The default Mode is Seam. If you select the combo button next to the mode, you will see the list of modes. Select Break. You are prompted to select an object to be split.

2. Select a plate. The name of the plate is displayed in the Plate field. You can select the plate before you enter the Split Plate command, and the results will be the same. You are prompted to select a splitting object. This is the object that will be used to create the break on the plate. The sketcher button is disabled. You are not allowed to use a sketch to create a break.

3. Select a splitting object. This can be a plane, a curve, a surface, or another plate. The splitting object should intersect the plate, but no test is done to verify this. You can select any number of splitting objects. If only one splitting object has been selected, then the name of that object is displayed in the Splitting Object field.

NOTE: When you change modes (Seam<->Break), the objects to be split are the same for each mode. But the splitting objects are different (a separate list exists for each mode).

4. The user procedure to create a break on a plate is basically the same as creating a seam on a plate. The result, however, is very different. The image below shows the result when the user selected the OK button. An additional plate was created.

NOTE: Unlike a seam, a break can not be edited or removed. A break is not an object. You can only undo the break action.


Unlike Creating a Seam on a Plate, new plates are created and the split plate is modified. The splitting object is set as a new limit of the resulting plates. When you edit the Deck panel, you can see that CROSS.71 has been set as a limit of Deck.

Create a new plate containing stiffeners, opening and seams.

B) Break the plate by the plane CROSS.71.

C) A new plate is created and the original plate has been modified. The stiffeners,  the opening and the seam have been cleaned and distributed between the 2 resulting plates.

D) Some of the other functions that were described in Creating a Seam on a Plate are available here:
  • The Elements List for the Splitting Objects
  • Selecting reference planes for the splitting objects
  • Selecting a plane to create a sketch (if you are creating a break on a shell plate).
