HOW TO DRAW NASSI-SHNEIDERMAN DIAGRAMS (cont'd)

Adding Loops
Add loops using the symbols included in the Nassi-Shneiderman library. These symbols were created using two perpendicular rectangles and a smaller white rectangle that joins them. We created these so you can stretch the two loop ends separately making the symbol easier to adapt to your diagram. Once the symbol is on the page, stretch or shrink the two perpendicular rectangles so the loop fits into your table.

Once the loop is the right size, select all three pieces (don't forget the middle white piece) and go to the Arrange menu and select Create Combination Object.
