Corridor on road with no curves

[cdtomberlin]

I have a road that was designed in the early 90's and for whatever reason there are no curves, just tangent points. Well I can't seem to get the corridor to model correctly on two of the turns. (I attached a png file, hopefully its clear enough to see the problem) Is there any way to fix this? And acquiring right-of-way for curves is out.

Thanks,

David

One solution is to add a curve that is just large enough to make the interior edges of the corridor meet. That should not impact the right of way.

You've just discovered the major flaw in corridor modelling with Civil 3D; the inability to go around a corner....;)

The only solution is to manually "fudge" it - search google for "civil 3d corridor bow ties"

Thanks, putting a small radius in worked. I will google the corridor bowties, I'm sure I'll need it.

You could also break it up into two separate corridors with a gap between them.  Then draw featurelines connecting them as needed.

EDIT:  I started to post this a long time ago -- then got called a way from my desk.  By the time I got back and finished the message and hit post, the 2nd post had been accepted as the solution.  Sorry.
