Power copies in Catia have a major limitation, the inability to manipulate the parts once a framework is created. In loo of this dilemma I decided to complete this weeks exercise in Rhino's plugin Grasshopper. 

Here is the definition for the resulting geometry.

The size of the array of parts is parametric and can be increased or decreased via this slider.

The individual parts extrusion height can be manipulated here. This is an example of a shorter extrusion.

This is an example of a larger extrusion.

To vary the aperture opening sizes I utilized attractor points. The distance from the attractor points to the center of the apertures is divided by the slider number shown here and results in a smaller or larger aperture size. 

Here the framework/surface grid is manipulated to change the overall assemblage of parts.

A final rendering of one of thousands of possible parametric solutions.

Overall (from the demonstration provided by Karl last week during class) I feel Catia excels at individual part creation, but in reference to an assemblage it falls short, especially compared to Grasshopper. My decision to use Grasshopper was mostly in reference to the fact that in Catia the framework could not be parametric and had to be fixed.
