The
button highlights. You can now click on the object to select it, rotate
previously selected object, or both select and rotate an object in a single
mouse action.
To
rotate an object, you do not need to select it first.
When this button is active, clicking on object selects it and dragging
the mouse rotates it.
To
restrict object rotation to the X, Y, or Z axis, we
can use Rotate Gizmo. |
- The
Rotate Gizmo is built around the
concept of a virtual trackball. You can rotate an object along
the X, Y, or Z axis, with free rotation.
- The
axis handles are circles around the trackball. Drag anywhere on
one of them, and you can rotate the object along that axis. As
you rotate along the X, Y, or Z-axis a transparent slice provides
a visual representation of the direction and amount of rotation.
If you rotate more than 360°, the slice overlaps and the shading
becomes more and more intense.
