Hi Shubhangi,
I don't know why your silhouettes are generating so many extra lines, but there is a parameter you can adjust, "depthJump", e.g. command:

graphics silhouettes true depthJump 0.1

If you just use command:

graphics silhouettes

...it will say in the Log what settings you have currently.  See help for this command:

However, since your display was also showing lots of little dots, maybe there is some other problem such as with your graphics driver.

I hope this helps,
Elaine
