The program includes Crystal builder generating regular lattices from
molecules through the spatial replication of models. It can be invoked from
the Build > Crystal menu.
Lattices can be generated by setting either the lattice parameters or
lattice vectors. Cell copies field defines the number of model
replicates in different directions. The model copies under construction can
be distinguished from the proper model by a selection color. After the appropriate
lattice parameters and the number of model copies were set, press the
Apply button to finalize the crystal generation.
