I know there is probably an easy answer to this, but I
can't get it too work. I want to be able to draw lines
that are connected point to point and the sealed as a
solid object when I add the last node.
I seem to keep getting singles lines that are not
connected. If I click on the two nodes and select join, I
get a new line added between the 2 points, while I want
the two points to join together to become 1 node.
