rotate XY coordinate system

[Daniel Finsler]

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)

While it's a little less elegant than a direct system, one way to do this is to create your off-angle stuff as a symbol, and then insert the rotated symbol in the main drawing. Another alternative is to create a layer link and rotate that. Both of these approaches have limitations relative to a rotatable coordinate system, however.
