building Mesomolecule

Hi,

I have been using Mesocite module as a research tool in surfactant.

But, I am beginner of Materials studio and molecular simulation.

I can build mesomolecules by "build -> build mesostructure -> mesomolecule"

But, it seems only to build linear mesomolecule (not ring-shape mesomolecule (beads connected together - like benzene molecule)), because there are only "add to branch points" option.

I am wondering if there is any method to connect the beads in order to make ring-shape mesomolecules.

thank. minsari
