corridor target

[hamidatut72]

how can i assign a point target to my corridor?

here i have an issue on my intersection on returning locations. i designing my accessing roads in a site. how can i specify a target point on my left side of returning (picture. corridor to the center of the circle)????point target to my corridor

Change the radius (or add a radius representing the top of the slope at the desired location) and then build the subassembly from the top of slope to the daylight. The radius of the circle will be greater than or equal to the horizontal distance to the daylight.

Hi,

A polyline with very small length would be considered as a point. 

However can't you do this by clearing bowties. 

Thanks

i tried that. but before reaching our point target, the corridor will tied up. and i do not want that. i just want that my corridor reach that point without tiding.

i am not allowed to change my design. my corridor must reach the center of circle. corridor create links perpendicular to the alignment. in this case i do not want that. there is any solution??

Mathematically no. 

You either increase the radius or change the side slopes to be steeper. 

Civil 3D changes the side slopes to clean bowties up. 

The math just doesn't work given your parameters. You have to change them to get a non crossing solution.

Again, it just is not possible to make a corridor do that.  As you already know, C3D builds each link perpendicular to the baseline, and for that region of your corridor, there is no way to have a link be both perpendicular to the baseline and reach that point.  It is mathematically impossible.

You have to come up with a creative solution using perhaps a small grading object, create a surface, then add it to your corridor's surface.
