AutoCAD REVCLOUD Command: How to Draw Revision Clouds

Draws a revision cloud made of arcs to mark changed areas of a drawing.

Command: REVCLOUD
English name: Revision Cloud

The AutoCAD REVCLOUD command draws a revision cloud, a chain of connected arcs that marks the parts of a drawing that changed. It is the standard way to flag revisions for review.

You can draw the cloud as a rectangle, a polygon or freehand, or convert an existing circle, ellipse or polyline into a cloud. The result is a polyline.

How to use it

Type REVCLOUD at the command line and press Enter.
Choose R (Rectangular), P (Polygonal) or F (Freehand).
Pick the corners, or move the cursor around the area to draw the cloud.
To convert an existing object, choose O (Object) and select it.

Options

Arc length (A): Sets the approximate length of the arcs in the cloud.
Object (O): Converts a selected closed object into a revision cloud.
Rectangular / Polygonal / Freehand: Chooses how the cloud outline is drawn.
Style (S): Chooses Normal or the brush-like Calligraphy style.
Modify (M): Redraws part of an existing cloud.

Notes and tips

If the arcs look too large or too small for your drawing scale, change the Arc length.
Keep clouds on a dedicated revision layer so you can hide them easily.
Use MLEADER to add a revision number or note next to the cloud.
