Density control rectangle menu in CST

Dear All.
I have CST 2006 Suite version, not installed Service pack.
In CST online menual, There is 'Density control rectangle of mesh' for mesh control of specific area. But,in my program, I didn't find that.
Where can I find that icon? or if not possible, How can I control of the mesh
for a specific area?
Thank you.

I am not sure what you are talking about. but you can select any part of your structure and right click\mesh properties. In the windows that will appear you will have several mesh control options. you can press "help" to know the function of each of them.
best regards,
Adel
