Turn off extrusion class objects

Hello Newsgroup,

since i experience some problems with the “extrusion” class objects like e.g. flippend surface normals when mirroring blocks containing extrusion objects, I would like to be able to turn them off and have my normal polysurfaces after having extruded a 2d shape…

is that already possible?

thanks for any feedback

Andreas

The command is ‘useextrusions’ and you get options for ‘polysurface’ or ‘extrusion’ . It is ‘sticky’ – once set, it doesn’t change.
