Autodesk® AutoCAD® provides a few commands (by default) capable of performing distribution and alignment functions. These commands are very complex, making the simple task of aligning and distributing something time-consuming and inefficient.
Align&Distribute is a plug-in for AutoCAD that provide a set of commands very similar to align and distribute commands present in other graphics software such as CorelDral®, Photoshop®, Inkscape®, and Illustrator®. Through this command you can easily and quickly align or distribute many types of objects with different shapes in the X, Y and Z axis.
If you want, you can get 'Align&Distribute TRIAL' on App Store and test these commands before paying for this version. The single limitation in the TRIAL version is that each command affects only 7 objects per selection.

IMPORTANT: This plugin is not compatible with AutoCAD 2013 or lower.
