Construction

Several tools are available to construct molecular models. The simplest tool is the Add command in the File menu, which makes it possible to generate a model from fragments stored in different files. Executing this command starts the preview of the added molecules. The initial model can be shifted or rotated and the added molecules overlapping with the model atoms can be removed. More complex construction operations are described below. The current program version supports:

• building of crystal lattice;
• building chain molecules from residues;
• molecular drawing by mouse;
• quantum geometry optimization;
• changing conformational parameters of molecules or their mutual arrangement in space.
