[rotate XY coordinate system]

in order to design buildings 'off regular' geometry, I'd be happy to have a coordinat system that can be adjusted to angles, so I could flip to a rotated geometry and draw that rotated bedroom, then flip back abain. (XY axes rotate around Z)

[print invert and transparent]

having switched a layer's transfer mode to 'invert' or to 'transparent' prints well on quickdraw printers. Postscript output seems to neglect the feature and prints all objects opaque. (tried on HP 755cm, LaserWriter 8500, print to pdf)
