Hello there!

I am following a video tutorial for my 3D class where we use Houdini as a Software.

Everything is going smooth so far but the problem is, i only have the top of my bridge and not any more levels under…

What can i do? It seems like it is somewhere i missed something, anyone good in Houdini and might have a clue whats wrong?

I post a picture of my bridge (i want it to have more levels, as you can see i only have the top of it)

Thanks in advance! Hope someone can help me

Please upload your project to solve it!
