The Delete command on the Edit menu apply to rows of grid inputs: elements, members, supports, loads, and load factors. It removes the selected row or rows from the grid. If all the elements of a part are selected, plus the blank row at the bottom for an open shape, the Delete command will delete the part and its elements. If all the loads in a loading are selected, plus the blank row at the bottom, the Delete command will delete the loading and its loads. If all the load factors in a load combination are selected, plus the blank row at the bottom, the Delete command will delete the load combination and its load factors.
The Delete command performs a special operation when you select elements that comprise a rib or ribs (see Insert Ribs). CFS recognizes when the preceding and succeeding elements are collinear, and rejoins them into one element after the selected elements are removed.
Since section elements, analysis members, and analysis supports may be selected in the graphic, you may perform the Delete command without using the grid in the inputs window.
The Insert command on the Edit menu applies only to the elements grid, because it is the only grid for which row position has significance. It inserts a row at the current cell pointer location. If several rows are selected, the same number of rows are inserted at the position of the first selected row. The inserted row or rows will be copies of the first row that was selected.
