As already mentioned above, all paths also have a direction. The start of the path will be shown as a small filled square, with all other points filled with white and so appearing hollow. Path directions have a decisive effect on the fill function when two paths cross each other. Please read the introduction to the Vector graphic module again about this.
To alter the direction of a path so as to cut holes
in
other objects, simply click on this icon. This reverses the order of
the points in the path. The old last point of the path will now appear
filled with black and so forms the new start of the path.
Tip: You can also use this function if you want to insert
additional points before the start of a path. Just reverse the path
direction, select the (now) last point of the path and then set the
new points. After this you can reverse the path direction once more
and you have extended
that path at the front.
