Hi,

I have encountered this question a couple of times on this forum but no one seems to have a answer for it. 

I have a road layer and I want to split it at the intersections. Does anyone have a idea on how to do this?

Thanks
GFG

Hello, 

Could you use Objects > Overlay Nodes?

That will place a vertex at the intersection. But that leaves the problem of splitting the line at that point.

I'm not aware of a tool that will split or cut a polyline at all the intersections of other polylines (presuming that's what you mean), it would be nice. If you're working with an older version of MI that doesn't have an acceptable "work around" tool, you might try CutPline created by Jacques Paris many years ago, it will allow you to click the node of a selected polyline where you wish to cut or break it.  It has a "Fast drive" option that will illiminate the extra user interaction of clicking dialogs.
 
You can download Cutpline here: http://georezo.net/jparis/ppcc/gisprogs.htm
 
Hope this helps

Thanks, I will have a look at CutPline. It seems peculiar to me that MI does not have this built in. Overlay nodes does most of the work already, they needed only to have included a function to split the line at the added vertex.

You can try this one:
http://www.routeware.dk/download/split.zip

You will have to select 2 links in advance or somehow add your own loop
around the function.

And this has been posted to the list before. Looong time ago, almost 10
years :-)

Hello GFG,

I am trying to solve the same problem. How did you end up solve it? Did you modify split.MB? Could you share it please? Thanks.
