This function generates elements based on the selected element pattern. One-dimensional elements will be dragged to form plate elements, and two-dimensional elements (plate) will be dragged to form solid elements (prism).
Note: In eta/DYNAFORM, only the same types of elements can be included in a part. For example, if the current part contains plate (shell) elements, the user cannot create any solid elements in this part. eta/DYNAFORM will display a warning message in the prompt window to alert the user.
