Is there a way to lock perspective mode for tracing curves when dealing with one reference image that is also in perspective?
zoom / set view / camera however you need it.
_namedViews
save the current view.
the _namedViews Panel has an “locked” option.
(you might need to restore the view once, before the lock is active)
you will also find this function on the viewport-name with right mouse button
or in the _viewPortPorperties panel.
there is also a
_lockViewPort
command
(but I recommend to use a named view - so you can restore it later…)
