AutoCAD Tutorial: Revision Clouds

Hover for help with video player controls

Video Tutorial Transcript

The REVCLOUD command has been around for a long time without any updates. Basically the REVCLOUD command draws a polyline comprised of arcs that looks like a cloud. The current cloud properties are displayed in the command window. The minimum and maximum arc lengths can be adjusted. Using different arc lengths creates a more interesting cloud. The maximum arc length cannot be more than 3 times the minimum. The arc lengths are not annotative so you have to take into account the scale of the drawing.

This is a freehand cloud. Click the first point of the cloud and move your cursor along the path and back to the beginning.

There are two styles of clouds: Normal and Calligraphy. In the Calligraphy style, the arc segments transition from wide to a point.

Prior to AutoCAD 2016, modifying the cloud produced unpredictable or undesirable results. Clouds created in AutoCAD 2016 can be stretched using grips. The REVCLOUDGRIPS system variable controls the type of Grips displayed: On for the new grips, Off for the old. Clouds can also be revised with the Modify option. This option allows you to remove or add to an existing cloud and trim the unwanted portion.

New clouds can be drawn by specifying a series of points (polygonal), freehand or opposite corners of a rectangle.

Now you can convert circles, ellipses, polylines or splines to clouds. The current arc lengths and style are applied. The displayed Grips are based on the underlying object.
