Intersection with target could not be computed

[Anonymous]

Hello,

I'm having the following error on a couple of stations:

20+660.00m:  Intersection with target could not be computed

I'm using the generic link slope to surface and sure enough there is plenty of surface data to daylight to it.  Weird part, when I go to the corridor editor and change the parameter slope from 4:1 (desired) to 3:1 it works!.... Has anyone ran into these issues before?

Thanks

Are you sure there is enough surface? What if your surface is 30% slope? 4:1 won't catch even if you have twenty-seven miles of surface on that side.

To check, draw a feature line at correct elevations between the two non-catching sections, try using grading tools to create a daylight at the slope you desire.
