Resetting Transformations
You can easily reset layers to their original position. With the Reset command, you can return the value of a selected element to the initial value of the active tool. For example, if the Rotate 
tool is active, the transformation angle will be reset to 0 and if the Transform 
tool is active, the all transformation parameters values will be reset.
When selecting elements in the Camera view using the Transform tool, always make sure that the Peg Selection Mode 
is deselected in the Tool Properties view. Otherwise, it will limit the selection to pegs only.
