RE: [MI-L] break polyline feature

[Peter Horsbøll Møller]

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: ftp://ftp.kampsax-gis.dk/pub/tools/   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 Horsbøll Møller GIS Developer, MTM Geographical Information & IT   COWI A/S Odensevej 95 DK-5260 Odense S.

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, I’ve 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   -----Original Message----- From: greg [mailto:[EMAIL PROTECTED] Sent: Wednesday, 12 April 2006 4:21 AM To: mapinfo-l@lists.directionsmag.com Subject: [MI-L] break polyline 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 ***This Email, together with any attachments is intended for the addressee only.
