Hello, Firstly I would like to thank for the previous question that you guys answered. I didn't had the time to reply on that and I do apologize.

Moving on, I would like to ask if the following way I've done is the right manner of drawing out the Road at a curve.
Steps I've taken:
1) Draw the TIN based on the Original Ground Level (O.G.L).
2) Place the road and earthlevel plan-view drawings together.
3) Used Alignment by Pi on the Road's centre lines.
4) Split into 5 segments of Alignment of Pi.
5) Draw the elements (CORRIDORTEMPLATEELEMENT) and combined them under a template (CORRIDORTEMPLATE). (Note: All elements' origin point are attached on the same base.)
6) Select the "CORRIDOR" option in the Tool Palette - then select the Alignment by Pi lines and then the Corridor Template.
7) Repeat the steps for the 5 segments of Alignment of Pi.

After all that is done, I am left with the result as shown on the right. Could I ask the following:
1) In between the corridors, there is an opening. Is this correct?
2) The road seems to float above the TIN O.G.L, is this correct?

I like firstly say I appreciate your time and effort in assisting and providing an answer. Looking forward to your response.

Thank you very much.

    Just a comment have a look at Civil Site Design running under Bricscad, it has lots of features for doing string design including superelevation. If you look in Youtube I am sure there will be a demo about using superelevation. Were I use to work still use it for road design importantly for reconstruction where kerbs need to move independently from each other both vertically and offset.

    This is an old link, sure there is newer ones. Near end can see cross sections being developed.

    Hello thanks for the comment ALANH,

    I also found Civil Site Design by a youtuber's video on Corridor BRISCAD. However, I do not have the capacity to purchase the full version of Civil Site Design add-on. Hence why I am doing a more 'unconventional' way of making a superelevated 90° turn and am wondering if this is right without the add-on.

    Appreciate that you provided the video tutorial too.
