From the view → toolbar to activate the Graphics tool, and then call the single line of text tool, hold down the left mouse button on the page to drag out of the rectangular box, input text, the content is generally "examinee answer must not exceed this seal line", and then set the required font, font size and other formats.
Draw the seal line
The seal line can be done using the line tool in the Graphics tool, and note that you should hold down the SHIFT key while drawing the line, otherwise the line may not be straight and it looks less beautiful.
Group objects
Click the rightmost selection button on the Standard toolbar, hold down the left mouse button to select all the objects you just created, and then combine the above objects from the right-click menu by selecting the combination → group command.
Rotate a grouped object
Right-click the Group object, select Object Properties from the shortcut menu, open the dialog box shown in Figure 1, and switch to the Location Dimensions tab.
Type 90 in the Rotate box so that you can rotate the grouped object 90 degrees counterclockwise, and then adjust to the appropriate position. If you feel that the length of the two-line seal is too short, you can first decompose the grouped objects and lengthen them appropriately.
Finally, we also need to let the seal line appear on each page of the paper. To do this, right-click the Group object and select the layout position → on every page from the shortcut menu to ensure that there is a uniform test head on the left side of each page of the quiz paper, and the final effect is shown in Figure 2.
