AutoCAD Civil 3D

[#1]

I was having this issue recently myself.

I ended up removing the profile curves from the main road and the side road from anywhere within the intersection and only had tangents with no curves in my profile.

I was then able to run the wizard successfully.

I then put my profile curves back in after the intersection was created.

I have no curves?

I opened an SR. I'm sure my order of operations is flawed.

Send me the file if you want. I'd love to take a peak under the hood.

Thanks. I'll getcha on Monday....

I got my SR response: evidently the intersection tool gets confused if the design alignments have more than 1 layout profile in them. I got rid of extraneous layput profiles and everything went according to hoyle

Horah!

[#7]

Aahhh. I recall that I had multiple profiles on one of my alignments also.

Did not realise that would have been the cause of the error.

Thanks for posting the solution.

UBETCHA

Either i'm missing something, or it's just been a long day of corridors. What's the solution to get away from this error?

I see your confusion kenny; I tagged my own solution and grabbed the wrong thread.

According to tech support the intersection wizard will work better if there is only one layout profile per alignment. So ya gotta clean up the trash prior to using the intersection wizard.
