Hi,
MapInfo 8.0 has a function called 'Break Polyline at node' (translated
from danish, so bear with me). This lets you break a selected polyline at a
selected node.
If you don't have MapInfo 8.0, you can here find a tool called
Splitter.mbx that will allow you to split a selected polyline in an existing
node:

I'm not sure if
this freeware version also supports splitting a polyline where there is no node,
but you can try it.
HTH,
Peter

feature
Hi
Greg,
Another approach might
be to use Objects/Overlay Nodes rather than polyline split. Then you can add
nodes to the polyline(s) at the required intersection points.
This will mean that
the original polyline remains as a single feature, but you will be able to
snap to that polyline wherever there is a node (you can make the nodes visible
using the Display Options for the layer in the Layer Control
dialog).
You can also then use
Polyline Split at Node to break the original polyline into separate features
at the nodes you have added, if that is what you need.
Actually, Ive often
thought that MapInfo should include a Parcelise function such as is found in
some other systems that allows you to take a linear network and split it into
separate connecting line segments wherever there are intersections. Perhaps
others know of some such tool for MapInfo?
Cheers
David

feature
HI
i have a MI user who needs to break a poly
line feature to add new connections to that feature. currently they make
the poly line the target, then draw a line in the cosmetic layer intersecting
the polyline, select the new line then use object polyline split.
this however draws a block around the new
line and breaks the poly line in more than one place - the user then has to
combine all the bits of the poly line
is there a better way to do
this?
thanks
greg
