Position two horizontal guiding lines (A, B) on the grid with Y=4.0 cm and Y=6.0 cm.
With Snap to Grid active, this should be no problem. With an INVERTER gate the
input and output leads lie in the middle of the block, 4 mm below the upper edge. In
order that the input and output are docked to the guiding line, the upper edges of the
INVERTER gate must be positioned (for a 5 mm grid spacing) at Y=4.1 cm and Y=6.1
cm. Right-click on the guiding line, select Edit guiding line from the context menu
and set the guiding lines to 4.1 cm and 6.1 cm.
In order that the blocks lie exactly underneath each other, insert vertical guiding
lines at X=5.0 cm (INVERTER gate) and X=8.0 cm (AND gate).
Now open the Gallery and drag the Inverter gate into approximately 0.64, the
position desired. If the function Snap to guiding line is still active, you will be able to
accurately position both blocks in the correct location. Your diagram should now look
like Figure 223.
