Chimera questions should be sent to chimera-users at cgl.ucsf.edu (CC’d here).

The Autodock Vina tool in Chimera does not have a grid spacing setting.  It only has the box center and size, which are in X,Y,Z coordinates of your atomic structure.  Atomic structures are generally in Angstrom units.

Maybe there is a setting to control grid spacing if you downloaded and used the Autodock Vina program directly (not using the tool in Chimera) but I do not know.  You would have to look at the Autodock Vina website for that information.

I hope this helps,
