rotate with alt doesnt work

There's a tiny padlock in the top-right hand corner of the scene view:

Try clicking that

Try to rotate with the Right Click and then use the Alt+Left Click again. This should fix the problem. Happened to me couple of times.

I think its because you have accidently pressed the cube top right. the three individual axis do xyz pressing the cube does perspective and enables alt. maybe

ALT KEY ROTATING(Orbiting) WORKS FINE (once one has had better experience with it ;) I have tested it repeatedly. I never got it to fail. Thus the reported problem about the failure of orbiting an object does not exist.

Orbiting an object is accomplished by:

1. first selecting a GameObject in the view window and pressing F
2. then ALT-mouseDRAG to orbit the object.

It only appears to fail due to the following 3 scenarios(in any combination):

1. The center of the pivot is no longer the center of the object you are focusing on. Thus the object you are attempting to orbit appears as if going from left to right on the screen when in fact it is going around in a large circle. Make sure the object in focus is not child or parent of another object that is at a distance in the scene, as the center of the pivot may be mid distance between the 2 or more objects You can either click on an object that will put the pivot near the object you want to orbit, or take the object you want to orbit out of the parent/child state.

2. The current object selected is the TERRAIN and or the Hand tool is selected, thus no access to other objects in scene. When the terrain is selected, the editor does not allow direct clicking on objects in the scene window thus click on any object in the hierarchy window to get OFF the terrain. Make sure the transform tool is not set to the little Hand as no selection is allowed if on Hand. Note: if the terrain is selected in the hierarchy, you may click any point on it then press F, and orbit that point.

3. The view vane(x,y,z,perspective, etc scene gizmo) is not in perspective mode Click the vane to set it to perspective mode.

Now you can:

• click on any object in the scene window, and press F to give it focus.
• or select object in the hierarchy window, hover mouse pointer over view window before pressing F.
• ALT-mouseDRAG will now work.

Remember that all 3 scenarios can occur at the same time, thus you will have to cover all 3 points above in some instances.

You have to do a simple thing .. just change the scene-view from 3D to 2D. It will give you rotate option with 'alt' key. (In case you are working on 3D project).
