First I created a curve and two others by using “geometry translate” function. Then, I took the second line and by using sin function I changed it to a sin curve. Then, I divided all these 3 lines (2 straight 1 sin) into pieces to be able to add ribs later on. After that, I divided rib curves into pieces this time to use them on quads later on. I created quads placed adaptive panels and adaptive tubes to ribs.
Then, I played with height parameter of the adaptive panel by using cos function along the ribs. Also I put an offset this time to prevent it to block the inside of tunnel.
Lastly, I wanted to put 2 point adaptive tubes parallel to ground along the structure. It was really tough to create the correct lists but finally I managed that as well.
Moreover, I played with material a lot to be able to put glass. I went to family properties changed it from type to instance property however it didn’t look good so I changed it back to default one.
