As you define the disks, you can make the inner one thicker, which will guarantee that it's color will show through and not be "mixed" with the outer one's color. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu On Sep 24, 2012, at 9:17 AM, Bala subramanian wrote:
Friends, I want to draw concentric circles of increasing sizes around the protein. To achieve this, i used the 'define plane' option to draw disk choosing I three reference atoms and drew the disks of increasing sizes and choose two different color for the inner and outer disk. Since the reference atoms are the same. If i change the color of the bigger disk, i get a weird appearance of the inner disk. I dnt know how to resolve this problem.
I would like to know if i can do something like making the disk transparent/removing the fill color of the disk.
thanks, Bala
