The Donut command inserts a connection point. You can use it if you for example have used the Line command to draw two lines forming a “T”. If you had used Xline instead, a donut would have been automatically inserted. Accordingly, this is not the case if you use Line, but you can put the donut in place afterwards using the Donut command. The result will be exactly the same.

 

Electrically the connection point has no effect in a “T-junction”, since the lines are connected to each other anyway. A connection point in a four-way junction though, makes all the difference in the world. That is however the only situation where a connection point really matters.
