This is a multi-use tool for accurate construction. Very useful for contraption builders and fort builders alike.

Updated version is included in the Phx3 SVN.

Version 0.9a:
Updated: Separate nudge and offset amounts; should have to type numbers in less frequently.
Fixed: lua error on rotate only.
Fixed: Minor parenting+physdisable issues.
Updated: Entire contraption mode now supports 'Autorotate to world' option - You can use this for snapping contraptions to the world axies. Very useful for moving advanced duped things between maps when you want it rotated right. Currently only works for turning, not pitching.
Added: default presets for mass rotation to world and parent mode.
Added: Undo for move only mode.
Added: optional undo for nudges (last checkbox toggles: default off)
