@Phil.E please accept my apologies if I sound pedant, just trying to improve an already excellent product.
Front, Right and Top are consistent with the block, and by definition are in the positive part of the plane, same for the Back, Left and Bottom, which are on the negative side of the plane, nothing new here.
What I'm saying is simply if the user is writing on the positive side of the plane (any) one would expect that the text created would be oriented as usual western text, written left to right, not specular, not upside down, and on the path, not under, while this happens when an user use the simple "Text" command on any plane.
I've enclosed another file just to show you what I mean, the 3 examples where created in a single drawing instance, on the front, positive side of the plane, weird enough if I draw the Path from left to right and then add my text this will be specular and upside down.
Hope it helps, thanks for your patience.
