Corridors from different models

[Nirvan]

Hi, I want to make corridors from few different models ( parts of corridor ) but there are problems with placement.
I want to stitch every model to each other, by I think it’s inpossible to do it perfectly manually, and it’s time wasting.
I tried with snapping but I can’t find correct value.

For example:

It there any tool which can help me?
Thanks.

Have you tried the snapping tool built in? It’s the V key.

You mean edit → snap settings ? Yes, but I have to hold ctrl key, V do nothing. And this tool transforms objects but not stitching to each other.

It’s very helpful if your modular parts have uniform sizes, say for example this tunnel is exactly 2x4x4 unity large
Then you can place the first part at exactly 0 0 0 and snap them together perfectly without nonsense after the dot and know they’re positioned right
It will also help when building rooms and connecting the tunnels to things because they will fit without extra work or even ugly scaling

The scaling will also be important if you’re tiling textures because you’ll want the edges of the textures to match when you put your pieces together, otherwise you’ll see your seams.

But first I must have model in unity large, I don’t know how to scale my model to it, I using cinema 4D and there are meters.

You can assemble your worlds more easily with a feature called Vertex Snapping. This feature is a really simple but powerful tool in Unity. It lets you take any vertex from a given mesh and with your mouse place that vertex in the same position as any vertex from any other mesh you choose.

With this you can assemble your worlds really fast. For example, you can place roads in a racing game with high precision and add power up items on the vertices of a mesh.

Using vertex snapping in Unity is simple. Just follow these steps:

Select the mesh you want to manipulate and make sure the Transform Tool is active.
Press and hold the V key to activate the vertex snapping mode.
Move your cursor over the vertex on your mesh that you want to use as the pivot point.
Hold down the left button once your cursor is over the desired vertex and drag your mesh next to any other vertex on another mesh.
Release your mouse button and the V key when you are happy with the results.
Shift-V acts as a toggle of this functionality.

You can snap vertex to vertex, vertex to surface and pivot to vertex.

Thanks PrimeDerektive, now it is fast and easy
