WOW, didn't see how old this thread was when I posted...hope Roger has found/formulated a plan to fit his wants (by now !). Z, I empathize...derailments and destruction in so small a scale (never mind Z-scale) can be disheartening. I admire the vision (68 year old eyes !) and manipulative skills of those who can work with N-scale, let alone produce such detailed, realistic dioramas, modules & layouts. 'Course your card/paper modeling friends are no less skilled in building ! I'm sure some of them even may produce enviable mobile, powered and controllable miniatures, too - but it's tough to fold a motor ? Hope you perused and passed on that new "Inkscape" release - I didn't know an appropriate, accesable place to put it. All the Best ! Bob C.
