Revision clouds show areas of a drawing that have been recently revised. When the REVCLOUD command was introduced to AutoCAD, I thought that they were for quick and dirty indications of revised areas of a drawing. Then I saw that people liked them to be neat!
If you like neat over messy, here’s the technique. Thanks to Brian Glover for contributing this tip.
- Draw the extents of the revision cloud using the POLYLINE, RECTANG, or CIRCLE command.
- Start the REVCLOUD command. AutoCAD displays the current minimum and maximum Arc settings.
- To change current settings, type A and press Enter. Follow the prompts to enter minimum and maximum settings. Size your arcs according to your page size. For 8-1/2″x 11″ (or an A sheet), use 1/8″ (about 3mm) and 1/4″ (about 6mm). For a 24″ x 36″ (or a D sheet), use 1/2″ (about 13mm) and 3/4″ (about 19mm) arcs.
- The default option is Object, so press Enter and select the object you draw around the revised area.
- At the Reverse Direction [Yes/No]: prompt, press Enter for No (if the revision cloud looks right) to end the command. If the cloud arcs are the opposite direction from what you want, type Y and press Enter.
Note: You can only convert one object to a revision cloud at a time. The REVCLOUD command works on any polyline (closed or not) or circle.
