Edit Transform

The edit transform dialog controls positioning, rotation, and scaling of objects. Translation: This allows the changing of the positioning of the object in the world. The increment controls the amount the position values change when you hit the up or down arrows next to the value.

Rotation: This allows the changing of the orientation of the object. The first value is rotation around the X-Axis. The second value is rotation around the Y-Axis (Up) and the third value is rotation around Z-Axis.

Scale: This controls the scaling of the object in the X and Y and Z directions.

Snap to Ground: This controls whether the object should be snapped to the terrain or to the floor the object after it is finished being moved.

Snap to Grid: This controls whether an object that normally snaps to the grid should still snap to grid after moving.

Lock Object: This controls whether the object should be able to be selected when the setting Lock Objects in the Object tab is checked. This allows the freezing of certain objects so you don't accidentally select and move objects that you don't want to. Checking this box means that it cannot be selected when Lock Objects is on and if it is unchecked means that it can be when Lock Objects is on. If Lock Objects is off then all objects can be selected and moved.

Orient to Surface: This controls whether when an object is moved if it should change its orientation so that the up direction of the object is aligned with the surface normal of the surface that it is above.

Snap Angle on Creation: Normally when objects are placed they are rotated so that the z-axis of the object is aligned with the negative direction of the camera z-axis. Snap angle on creation will change the angle to be an exact value. For instance if the snap angle on creation is set to 90 the object's starting orientation will either be 0, 90, 180, or 270 degrees depending on the orientation of the camera.
