Can`t see 3D Buildings

Hi I am pretty new in Unity and I am having some problems to see the buildings that I import in the Unity. When I first import# there was no problem and I zoomed in and zoomed out. After that when I import again, I see the axes but I can`t see the buildings. Can anybody help on this? Thank you.

 

try selecting the model from Hierarchy and press F key (to frame selected)
could be the model is not at 0,0,0 position, or scale is too small or too big.

or when you select model in Project window,
check inspector, there is 3d preview at the bottom, so can check if imported file contains any mesh

 

Thank you very much for your reply. I fixed it with your help. I would be so happy if you answer my next question. I want to see inside of the building like in the second pic. But I can only see the building from above (see the pic). I can only move the building or go depper. Can u help me for this ? I appreciate it. Thanks for your time.

 

is that from scene view?
Try to press key "2" to switch between 2D and 3D mode (if it happens to be 2d mode)

 

I can only move the camera in x z and y axes. In the figure, I want to rotate the camera towards to cube. Is it possible to rotate the camera ? Thank you very much.

 

yes, press E to rotate, W = move (also from the toolbar can toggle those tools)

check editor tutorials for more info:

Attach this script to the camera:

Code (CSharp):

1. using UnityEngine;
2.  
3. [ExecuteInEditMode]
4. public class LookAt : MonoBehaviour
5. {
6.     public Transform target; //The cube
7.  
8.     void Update()
9.     {
10.         transform.LookAt(target.position);
11.     }
12. }

The camera should look at the cube while in edit mode and in play mode.

 

Also, if you hold down the right mouse button you can move the camera with FPS controls (i.e. WASD to move in four directions and you can look freely by moving the mouse.) That makes the scene view very easy and intuitive to navigate.
