Creating an intersection with 3 alignments/problems with t-junction

[marirf]

I´m trying to create an intersection with 3 alignments, however, I´m not succeeding because when it tells me to chose a main road its not possible to chose any of three and does not starts the intersection wizard. Does anyone knows what's going on?

Also, I have an intersection, and near it I have to build another one but it keeps showing me the message: "The primary road

for this T-junction will result in a circular dependency with the existing intersections." 

Anyone, please?!

Thanks 😉

Help other help you by telling us the version of civil 3d you are using, including 32 bit or 64 bit.

Attach a drawing file if possible or atleast a screen shot or two.

Sorry, first time here!

There are 2 pictures attached, the one named "3 alignments-main road" shows my problem to create an intersection with three alignments. It keeps showing the message to select the main road, but, when I choose one of them it keeps asking me again and again, the intersection wizard does not appear and I'm not able to create the intersection. The other picture shows my problem to create another intersection and appears the error message: "The primary road for this T-junction will result in a circular dependency with the existing intersections." 

Tks 😉

I think it can only create an intersection from two alignments.  The main road alignment for a T intersection must continue through the intersection.

It's a little hard to tell from your attached pics, but a couple of rules of the Intersection Wizard are:

1. If an alignment intersects another alignment twice, it cannot create an intersection and will give you that error.

2. You can't create an intersection with the IW using three alignments. Just do it old-school and forget the IW for that intersection.
