REVCLOUD creates a polyline of sequential arcs to form a cloud-shaped object. Revision Cloud help mark your drawings by highlighting some important parts when review or redline drawings.
You can create a revision cloud from scratch, or you can convert objects, such as a circle, ellipse, polyline, or spline, to a revision cloud. If DELOBJ is set to 1 (the default),the original object is deleted once you convert an object to a revision cloud.
You can set the minimum and maximum default values for the arc lengths of a revision cloud. You should notice that the maximum arc length can't be more than 3 times as big as the minimum arc length.REVCLOUD stores the last used arc length as a multiple of the DIMSCALE system variable to provide consistency among drawings with different scale factors.
Make sure that the entire area to be outlined with REVCLOUD before using the command. REVCLOUD can't be transparent used and real-time panning and zooming.

System Variables Reference
DIMSCALE: Sets the overall scale factor applied to dimensioning variables that specify sizes, distances, or offsets
DELOBJ:Controls whether objects used to create other objects are retained or deleted from the drawing database
