pro-e wf, feature window like 2001

[opua]

again save everyone, as I wrote in the previous post, I find myself using pro-e wildfire after years when I worked with the 2001 version. it had these days I noticed a strange aspect, namely that in redefining some features, such as rays or sforms (of old projects realized with the 2001) with the wf, the classic window appears (the same that appeared in 2001) containing sform supfce, neutral plane etc... While if I create for example a sform directly in the wf and therefore not as feature inherited from 2001 the command mask has like to say, a different aspect. . .
taking as reference the sform command to describe this aspect, it also highlights the *sform hinges* option, but what exactly is it? matches the old neutral plane?

from what I know, the commands have been rewritten, in order to be used with the "ribbon" interface nuov, percui loading the old prewild files, chamfers, sforms, some sheet commands, etc, should be redefinable through the old interface.
In the specific case, the deformed command requires the surfaces to be shaped, the hinge (i.e. a perpendicular plan to the selected surfaces) and a traction direction
If the latter coincide, the hinge would be the old "neutral plane".
