23rd 'shape' file for CPO3D.

An array of round holes in a flat plate.

The technique used here is to sandwich 'discs with holes' between 'plates with square holes'.  So the round holes are in discs that are sandwiched between flat plates that

have square holes in them.

The 'check for overlapping' must be disabled  -this involves great danger for the legitimacy of the other electrodes of the system (not included here), so these other electrodes should be set up and tested separately.

The 'transform' option has been useful here.  A single square hole was set up for the lat plate at z = 0.1, between the origin and (x,y) = (1,1).  This was then transformed, using a copy file, by z = -0.2.  The copy file was then collated with the original file and the disc centred at (x,y) = (0.5,0.5) was added.  We then have a single 'unit cell'.  This was then transformed by (x,y) = (1,0), (0,1) and (1,1), using copy files, and then the copy files were collated with the original file.
