Help with making a (simple) mesh

Hi there.

I'm trying to make my own mesh, and I don't know what to do. Let's say I start with something like this (a tunnel kit piece)...


... and I want to achieve this (a curved tunnel)...


Looks pretty simple task but I'm really desperate how to make such thing.

Please help somebody.

The short answer is that you would create the tunnel kit piece, then extrude from the ends, and rotate the extrusions. Doing this is not hard, but then it's not first Blender creation simple, either. There is a tutorial on the Blender Guru website on how to create an underground subway scene that deals with the general topic (see ... rt-1-of-2/). But I would recommend first taking one of the free on-line courses available at or at Once you have some level of competence with Blender, it will likely be pretty obvious how to achieve what you want.

Thanks for reply.
Actually, I got some skills in Blender, although I'm considering myself as a total beginner. I already know about that underground tutorial (it was my first Blender tutorial ever) and even I didn't do it so good, I learned a lot from it. I think that's the major problem with tutorials - they show you how to perform a specific task but they won't show how to perform a specific task YOU want.

Anyway, I tried two different techniques to solve my problem:
1. spin tool. This is pretty precise tool but there's one problem with it - textures are weirdly handled by it (see the picture).


2. path/curve technique (used in that tutorial). Here I didn't get too far because I even didn't bend the mesh, I found a problem - stretching. I don't know how to explain it well (I'm not a native English speaker), but if you look at second picture, you'll notice that bolts on the rail are different on both sides - on the left it's shrank and on the right it's stretched out.
