Hello Everyone,
I am using Civil3D 2018 and trying to create an alignment with a tight radius in it. I keep getting tangent violations at 3 points. How can I correct this?

Dear Friend,
You can use floating curve to achieve this target.
This video might help.

Thanks
Thanks the video was very helpful and I was able to create the alignment without any tangent violations.
Thank you,

Could you please post a drawing with your requirement. That would make me more concentrated.
See this video if it helps.
I don't know the standard IRC values for spirals. I just put random value for video.
Similarly you can try with other spiral options in geometry editor when creating spirals.
Thanks
This looks bit tricky.
What I suggest is this.
Create arcs over those curves and delete them.
Now create new curves with same radius using fix curve option. But do not connect them to the tangents or do not connect the curves with each other. Make them separate.
Then use free spirals to connect the curves to tangent ends.
Use reverse spirals to connect between two curves.
Can u please make a small video i can understand easily.
i will try in your way
i found the other alternate way to fix this curve if we reduce speed.this curve fitting will be done.
but i want to maintain same speed 100km/hr
