I'm not sure if this will be helpful or not, but maybe something similar to the way the UCSF Chimera deals with multiple structures would be possible? I have no idea what this would entail in terms of coding or the data model. Anyway, in Chimera, at the bottom of the main screen there are checkboxes for each model. Anything checked is active and affected by the mouse, and anything that's not isn't. One can also open the Model Panel which allows the same as well as controlling whether or not a model is visible. Visible and Active are independent flags. Analysis of course already has an equivalent of visible. Andrew On 4/16/10 8:17 AM, "Wayne Boucher" <[log in to unmask]> wrote: > Thanks, that's helpful.
