Image-O-Matic is a batch image exporter that can be used in three ways:
1) Select a family instance and one of its instance parameters. Then specify minimum, maximum, and increment values. Image-O-Matic will increment the parameter through this range and create an image file for each value
2) Select some or all of the phases in a project, and an image of the active view will be created showing each of these phases. To use this option, press the ESC key after running the command instead of selecting a family instance.
3) Select a Displacement Set and increment its offset in either the X, Y, or Z direction.
