Does anyone here use revision clouds?

I frequently need revision clouds.

Seth, I suggest you download a demo of Bricscad and try out its revision cloud tool. It is the best I've seen. It is essentially a free hand tool. Like Autocad, an arc length variable specified by the user is required, but the Bricscad version has minimum and maximum arc length inputs. The arc length input is what makes scaling simple and allows the user to produce decent looking clouds quickly and without subsequent editing.
