Alan and Sarah,
There's a mapbasic developped by Jacques Paris that will do just that. You
may
have to change the line direction of some of your objects in order to draw
the half
buffer on the right side, since the application will ask you if you want the
half
buffer on the right or left side of the polyline. Mind you, there's a
mapbasic that
will allow you to do that to!
