General Plop directions...

Start Plop, click on "Automatic Cell Design". Put in the numbers it asks for. 
Take a guess as to how many points you'll need. When done, click "Start" to 
start the optimization. When it's done, if the "Visible RMS Error" number is 
less than 4e-6 (a suggested stopping point - you can accept a design with a 
higher RMS error - you are the boss) you are done. If not, click "Automatic 
Cell Design" again and change the number of points...

You can also go to the main window and click on "Material" if your mirror is 
not Pyrex (which is what's assumed by the Automatic Cell Design).

When you have an acceptable design, click on "Part dimensions" to get the size 
and shape of each part you need to make. Click "rotate" if you want to make 
the parts easier to determine sizes...scroll down using the scroll bar to see 
more parts.
