The Revision Cloud tool is enhanced in AutoCAD 2016 to provide more flexibility. It's accessible from the Annotate Ribbon panel and includes three methods of creation: rectangular, polygonal, and freehand—in addition to the Command line option to select an object. The last used creation method is remembered the next time you run the command. You can set your own default creation method using the REVCLOUDCREATEMODE system variable.
Whether you create rectangular, polygonal, freehand, or object revision clouds, editing their size and shape with grips is intuitive and easy. The number of grips displayed for revision clouds has been significantly reduced. The location and behavior of grips is based on the shape of the revision cloud. For example, if the revision cloud was generated by selecting a circle, it will include a center grip and four quadrant grips enabling you to edit it like a circle. If it was generated by picking polygonal points, it will include vertex and midpoint grips. If you prefer legacy display of grips, you can set REVCLOUDGRIPS to Off.
In addition to easier editing with grips, a new Modify option enables you to draw new revision cloud segments and erase selected portions of existing revision clouds. This was the #4 AUGI wishlist request!
