Corridors Intersection No Solution

Anonymous — Mon, 31 Oct 2016 14:32:37 GMT

Dear Sirs

I am having issues creating a intersections between 2 roads, the command line keeps saying "no solution" and the intersection corridor come up as question marks.

It also seems to be failing in producing a LHS alignment.

Regards

Is that white line in the middle of the intersection supposed to be your Road 2 alignment? Shouldn't it extend further up Road 2? The picture makes it appear to stop even before you get to the ends of the curb returns.

The white is just a polyline not part of the design

The kink at the end of the poly line can't help.
Also, any chance you are using DS / alignment and or profiles ?

This is an example of why it is important for those of us posting images that "detail the problem" to use isolation to only show the relevant geometry. An image with base linework, makes itself unclear.

Try creating your image again or post your drawing.

Another option is to create the Intersection manually. For anyone who might need a primer: http://timsc3dblog.blogspot.com/2014/10/corridor-intersection-primer-manually.html
