is there a way to fix having started a group in a wrong workplane?
<dalias>
it's in the xy plane but i want it in a plane parallel to the xy plane but shifted away from it, i think

(for extrusion not starting at 0)

unfortunately not
<whitequark>
you could try editing the file (it's mostly plain text) but that voids your warranty

oh, you're Rich Felker, right?
<dalias>
yes
<dalias>
i ended up just recreating it. (actually c&p, then restore constraints manually) but creating workplanes seems hard in general
<whitequark>
unfortunately, yes
<dalias>
i couldn't find a good way to make the necessary line segments and point for it
<dalias>
best was to put some construction lines in the xy plane then make a new xz workplane to put a single point in, then use them...
<whitequark>
oh
<whitequark>
nonono, there's an easier way
<dalias>
it would be nice if you could use axes rather than having to make gratuitous lines to define what plane you want it parallel to
<dalias>
but i couldn't get that to work
<whitequark>
there's been a patch that does this
<whitequark>
we had to revert it because of compatibility issues
<whitequark>
the file format is very baroque and needs to be completely redone
<whitequark>
anyway
<whitequark>
the special case of a workplane parallel to xy/xz/yz is easier
<whitequark>
you make a point, then orient your viewport parallel to the axes you want
<whitequark>
then make a workplane through that point (W)
<dalias>
that's good to hear. i couldn't figure it out tho
<dalias>
ah
<dalias>
i didn't realize the "just using a point" thing depended on the view orientation
<dalias>
that's why i got very weird results when i tried it
<whitequark>
I *think* it's in the documentation
<dalias>
i saw something about it (forget whether it was docs or a tutorial, i had a lot of tabs open)
<dalias>
but i failed to understand it was the view axis
<dalias>
if a workplane is made based on point/lines though, it's parametrized on them and movable via moving them, right? or are they just reduced to constants at creation time?
<whitequark>
if it's based on points and lines it is movable.
<whitequark>
if the lines ever become collinear this will cause numerical instability
<whitequark>
so it's a good idea to constrain the lines perpendicular or at an angle
