General

1. How I can show the metal environment?
- The structure should be large enough to have all desired fragments (See the "Generation Options" dialog). Select the atom, invert selection and hide it (Ctrl+H). Select the atom again and execute the "Fragments->Expand Nodes" command (Ctrl+E) as many times as you need.
2. Cannot save my work to file
- currently there are some problems. If you have been using topological analysis, then try to run the "Network-.Evaluate Topology" command -  this should sort it out. Otherwise try to export the work into an alternative file format.

Topology

The topological network should be constructed before following the scripts.

1. How full environment of a topological node can be shown?
- Hide all atoms and execute the "Network->Evaluate Topology" command. The command puts vertex symbols into the clipboard and shows the nodes which are the closest to the center of the structure. Right click on any element of the structure (if visible) and execute the "Fragment->Hide Bonds" command. Then right click on the desired node and execute the "Atom->Topological Term" command. Press the "Select Cycles" and "Select ACycles" buttons and activate the main window. Invert selection and hide it (Ctrl+H). As the result all rings, found during the analysis will be shown.
2. How I can show coordination spheres of a node?
-  Select the node, invert selection and hide it (Ctrl+H). Select the node again and execute the "Network->Expand Nodes" command. To show the next coordination sphere press Ctrl+A to select all visible nodes and execute the command again.

1. The drawing is too slow.
- it presumably happens due to high resolution of the scene. This can be changed in the "Scene Parameters" dialog: simply change the "Rendering Quality Options".
