With any file that contains animations, you can specify a viewport to be automatically used when playing back the animation in Arbortext IsoView. This viewport must be saved under the name IsoViewExtent. Arbortext IsoView will only recognize the viewport if it has this name.

The option of selecting a specific viewport for animations is very useful if, for example, only a small section of a drawing is animated. You can specify a viewport that zooms in on this animated section. Even if the drawing needs greater space due to the movement of objects that takes place within the animation, you can specify the appropriate viewport for this.
