Hello... I am struggling with the Hiking Club Logo in the book. When I get to adjusting the "C", for some reason I don't get the "line segment". I have followed the book to the letter, but I still get no line segment.

Any ideas?

Ok, just to make sure we're on the same page, you're talking about Step 4.b.iii., correct?
Are you sure that the same 2 nodes that you converted to cusp or corner nodes, are still selected when you click the button to make it a line segment?
