Could you explain a bit more?  Each separate object in the Geomview
browser (i.e. each one you load) does have an independent coordinate system,
and is displayed using those coordinates.
To specify transformations explicitly rather than using interactive controls,
you can do that with the "xform-set" and/or "transform" commands.  E.g.

(xform-set  thing1
    1  0     0   0
    0 .5 -.866   0
    0 .866  .5   0
  1.5  0    -1   1
)

specifies the transformation from "thing1"'s coordinates to those of the world
(written assuming points are row vectors multiplied on the left).
Equivalently

(transform thing1  world world  rotate 1.047 0 0)	# Rotate 60 deg about X
(transform thing1  world world  translate 1.5 0 -1)	# Translate by 1.5 0 -1

Is this what you mean?
