The Rectangular revision cloud tool

The Rectangular revision cloud tool will make a revision cloud in the shape of a rectangle. In the following example, we will learn how to make this type of revision cloud in our drawing:

1. Select the Rectangular tool from the revision cloud flyout or use its command, REVCLOUD.
2. Now, the command line will prompt you to specify the first point of the revision cloud. Click on the point from where you want to start it.
3. Then, the command line will prompt you to specify the opposite corner of this Rectangular revision cloud. Click on another point so that it includes the area you want to highlight using the revision cloud.

In the following figure, I have highlighted the bed blocks using revision cloud as their size is too big for the room and needs revision:

Revision Clouds generally have a standard arc length that will be automatically adjusted as per the scale of the current drawing. So, when you make your first revision cloud, it will be made with the proper arc lengths. This is, however, a new feature added in the 2021 version of AutoCAD and if you are using an older version of AutoCAD, then you may need to adjust the arc length of the revision cloud as per the drawing scale:

1. To adjust the arc length, start the revision cloud command. 
2. Click the arc length option from the command line.
3. Type in the approximate arc length and press Enter. If you are using a version older than 2021, then you will be prompted to specify the small arc length and the large arc length.

Once you are done setting the arc length, make revision cloud and it will be made with specified properties. Revision cloud is a different object type called Revcloud, and when you hover your cursor over it will show it as such.

So, as you have noticed, adding Rectangular revision cloud is similar to adding a rectangle to a drawing and just like a rectangle, this revision cloud can also be modified after its added to the drawing using the multifunction grips.
