Another user with the greyed out menu items here.
I drew a basic rectangle an as usual it surfaced backface up so I right clicked and the option to reverse faces is greyed out.
Using the drop down edit menu, selecting the same face, reverse faces is no longer greyed out.
.. interesting to note, I did nothing to change any settings anywhere - thought gee.. I should go get some screen shots since there were other greyed down items on the edit list and it seemed to have fixed itself.. until I drew another basic rectangle and tried again to right click.
Using the drop down edit menu instead of right click seems to fix it.. odd
I know.. I should be in the newbie forum
