RevisionCloud
A RevisionCloud is a graphical "cloud" that can be displayed on a view or sheet to indicate where revisions in the model have occurred.
RevisionClouds are view specific and can be created in most graphical views, except 3D. Unlike most Elements, RevisionClouds may be added directly to a ViewSheet. Each RevisionCloud is associated with one Revision.
When a RevisionCloud is visible on a ViewSheet (either because it is directly placed on that ViewSheet or because it is visible in a View placed on the ViewSheet), any revision schedules displayed on the ViewSheet will automatically include the Revision associated with the RevisionCloud.
Note also that when a RevisionCloud is created in a ViewLegend, it is treated as a legend representation of what a RevisionCloud looks like rather than as an actual indication of a change to the model. As a result, RevisionClouds in ViewLegends will not affect the contents of revision schedules.
RevisionClouds are created from a collection of sketched curves. Each curve will have a series of "cloud bumps" drawn along it to form the appearance of a cloud. There is no requirement that the curves form closed loops.
