COMSOL 4 Geometry Problem
 

Question 1) I draw a circle and then use array function to copy it multiple times . The reason for doing this is to place these circles at a particular distance. Now I want to change the radius of some circles which were copied via array function. How can I peform adjustment in radius of these circles?

Question 2) When the array pasting is performed, usually a tag is added to each individual item which make it messy. How to remove those tags?
