You can select any of the following as boundaries for plate systems:
-
Plate systems.
-
Profile systems such as stiffeners, beams, or edge reinforcements. A plate can be bound to the webs and flanges of profile systems.
-
Standard members created in the Structure task. A plate can be bound to the webs and flanges of members.
-
Built-up members, but only when the web or flange plate systems of the built-up are selected.
-
Sketched boundary curves.
Sketching Limitations
Sketched curves must extend beyond other bounding objects. In this example, the curve for a linear extruded deck extends beyond the hull boundary:
In this example, the bracket boundary curve extends beyond the top and bottom flanges:
Bounding and Splitting
A profile or member cannot be used to both bound and split a plate at the same time. In the following example, the two plates can be created in two different ways:
-
The plates are created separately, each using both members and a sketched line as boundaries.
-
A single plate is created using the horizontal member and two sketched lines as boundaries. After creation, the plate can then be split by the vertical member.
