<freem> Hello. Is it possible to modify the workplane of a group?
<whitequark> you mean change it after the group is created?
<whitequark> unfortunately not
<whitequark> you could try editing the savefile (it's basically text), but it is not supported in the interface for a good reason; this might corrupt later groups
<whitequark> however, if you load the modified file and it looks OK, there are no hidden issues.
<freem> I see
<freem> so, if that group is the last one, there is no risks?
<freem> not that it would take that much time to redo the work, but... it may, since I'm learning the thing
<freem> hum
<freem> maybe a better solution would be to be able to make the extrusion backward? Is there is a way to change the direction (the normal, I suppose?) of and extrusion?
<whitequark> yes
<whitequark> you can drag it through
<whitequark> or you can attach a dimension constraint to any extrusion edge parallel to the normal and enter a negative value
<freem> whitequark, which version do I need to do the negative value for distance? Maybe debian's one is outdated because it seems this does not work
<freem> anyway, yes, manually putting the direction to the other direction did work, I should have thought about that, thanks for help
<freem> still learning the ropes :)
<whitequark> should work in 2.3
<freem> hum, Debian have 2.3, but the neg distances seems to be be always positives?
<freem> which, in a way, makes sense.... a distance is always positive in my mind.
<whitequark> yes, they're signed internally, but the sign is hidden, since it's not user-relevant
<whitequark> (they have to be signed for the solver to work)
<whitequark> when you enter a minus sign, the sign is flipped internally
<freem> whitequark, it does seems to, here
