Hi there.
I’m using Rhino (5.7.31213.18395, 2013-12-13).
Command: _NewFloatingViewport
View projection ( Projection=CopyActive ): _Projection
Projection ( CopyActive Perspective Top Bottom Left Right Front Back NamedView ): _Perspective
and then
Is it zooming in a perspective viewport does not affect linked perspective viewport?
Is it possible?
