A revision cloud is an Isogen customization feature that typically indicates a section of the pipeline that has been revised. An example of a traditional revision cloud as it appears on the isometric drawing is shown below:
The traditional representation of revision clouds on the isometric drawing can be modified to output a polygon enclosure, which can optionally be filled with a color.
There are two revision attributes. The first is the pipeline revision attribute,
which defines the current revision of the whole pipeline. This attribute is commonly
incremented whenever a new revision is issued. The second is a component revision
attribute. This attribute is available for all components in the pipeline and defines
the revision that the component was introduced in the pipeline. For revision clouds
to be activated on specific components, the pipeline revision and the component revision
must be equal.
-
On the Home screen, select Revision Clouds in the Drawing Area category pane.
The software switches to the Configuration View and displays the Revision Clouds panel.
-
Expand Settings.
-
Set Enabled to True.
-
Use the Distance box to specify the distance from the component centerline to the revision box.
-
Define the required values for Colour and Layer. The numbers you specify depend on the drawing system being used, such as AutoCAD or MicroStation.
-
Use Enclosure Style to specify whether the revision box enclosure is a cloud or a polygon. If you select Cloud, you must also define Minimum Cloud Arc and Maximum Cloud Arc. If you select Polygon, you can optionally define a fill color for the enclosure.
