I am wanting to bring in some 3D models from an outside source (files from the Protein Data Bank in .vrml or .mol2 file format) and currently I do not have the ability to import them into Maya. Does anyone know of a plug-in that might allow me to bring in those file types?

Also, I have used Maya on other computers (not my own) and there was an option in the Preferences to turn on a projection for selecting edges and faces (where an edge/face turns green when mouse passes over it letting you know that would be the one you'd select if clicked). That is not available on my version. Does anyone know where I might be able to find this option (if it is a separate option that needs to be "turned on" like from the plug-in manager, or is it only available for certain Maya versions)?
