Alignment Queries

[onsionsi1]

Hello there,

I faced a lot of problem to draw the attached file (loop) and other issue my client didn't like to draw a zero line (0.001) to attach spiral in some cases so is there any idea or 3rd party programe to draw alignment without a zero length.

For your advice 

Thank you in advance.

The file you shared are just splines. Are you wanting to create an alignment that is comprised completely of spirals?

Thank you Mr.Brian for your action 

Attached file is an autocad DWG and you will find my civil 3d alignment and i would like to attach a spiral between each two compound or reversed curves

Also i have an issue if the main road is spiral what can i do.

Our director told me that we can solve this issue in MX Road but i think we can solve anything in Civil 3d so what is your opinion?

For your advice.

Eventually, do you have any background about MX Road and is it really give a good solution for our issue and i listen it also give a better corridor than Civil 3d and the following link also describe other issue in civil 3d
