Good! I just spotted that too.

Something to try: epspline Edit->Preferences dialog, 'POV-Ray Options'
field, append /NORESTORE (I'm not certain it'll help but looks worth a try).

Well, for each individual object, e.g. "foo", the exported file has a
macro foo_NORMAL_TRANSFORM that scales the object to one unit in the
greater dimension, centers the object at <0,0,0>, and does the inversion
to expected orientation. That macro can be used in SDL, or
before including, declare foo_USE_NORMAL_TRANSFORM and that will enable
a transform { foo_NORMAL_TRANSFORM } within a conditional within the
object declaration.
What is missing is a similar macro for all the objects of a type (prism
or lathe) collectively that could be applied to a union or merge. Maybe
next release.

Well, there's no limit to good ideas, but there is a severe limit on the
time I can spend on epspline. It was began to scratch an itch and
released in the hope it is helpful, but it brings no income (which I
happen to need very much).
