This video will show the basics of working with Revcloud objects in AutoCAD. Please refer to Tutorial 2-7 for more information.
A Revcloud is just a fancy polyline full of arcs. They are used to indicate an area that needs revision. If you are starting out in a new job as a CAD operator, you will likely be looking at these or need to know how to make them. A lot of entry level CAD work deals with revisions and corrections.
It's a short, easy video.
