Hi,

This may already be implemented, but I couldn’t find it - the nearest equivalent feature I know of is copy/combine, but that only works on whole models, not taking into account selections.

I was wondering if it would be possible to implement a feature creating a new model comprised of all atoms in the current selection? This would be particularly helpful when combining many parts of multiple models, or when creating a separate model consisting of a subselection of the current model.

This can be done at present using a combination of copy/combine and selecting and deleting those parts of the copied molecules that are not in the selection, but this gets messy for complicated selections.

Hi Olivier,
This is a reasonable request/idea, and I'll open a feature-request ticket for it.  However, with our current focus on implementing Chimera 2, it may be some time before this feature gets implemented (in Chimera 1 or Chimera 2!).
Perhaps there's an easier workflow?  Select all the parts you want put into the new model, invert the selection, delete the unwanted parts, and then combine into a new model.  You may want to save a session before the delete step, depending on what you want to do with the new model relative to the old models.
 I hope this helps.
