In CFD-VIEW, a model rotates about its geometric center by default. For rotating complex models, this may not be very convenient. CFD-VIEW has a feature that allows you to set the rotation point at the center of any data object of your choice.

For example, in the combustor model shown in Figure 1, we would like to set the center of rotation about the center of the surface called "exit". To do this, in the object explorer, select the surface object called "exit", right click, and then click on "Rotate about exit". You can also set the rotation point from the Menu bar, by clicking on 'VIEW -> Rotate About selected'.

Figure 1.  Setting the rotation point about the surface named "exit".

The center of rotation can be set on any CFD-VIEW data object such as volumes, surfaces, spray, trace, etc.

Performing a "Ctrl+G" operation to refit the model into the graphics window will reset the rotation point to the geometric center of the model.
