There is a tricky way to do a projection of a map in Chimera. You can
use the map binning capability. For example, if map #0 has 144 planes
along the z axis I can add all those planes with
vop bin #0 binsize 1,1,144
This can be done with a dialog instead of a command using Tools / Volume
Data / Volume Filter, filter type bin and type in the bin size as 1 1 144.
You also want a view along an axis other than x, y or z it sounds
like. To do that you would resample the map on a new rotated grid so
that the z axis is along the desired projection axis. The following
video shows how to use the Chimera volume dialog subregion selection
capability to do that
