When meshing a plate, the members along its perimeter are not always split together with the plate. This occurs when an edge of the plate is already divided into multiple members.

To clarify, consider the following example:
We have a rectangular plate with vertices numbered 1 - 2 - 3 - 4. Three edges of the plate consist of a single member, while the edge between joints 3 and 4 is split by an intermediate joint, 5.
When the plate is meshed, members 1-2, 2-3 and 1-4 are divided as expected, whereas members 3-5 and 5-4 remain unchanged.

Although this can be corrected manually, it becomes time-consuming and increases the risk of errors when dealing with a large number of plates.

Therefore, it would be useful if future versions of SACS could automatically divide all members along the plate perimeter during meshing, even when some edges are already divided into multiple members.
