Hello Chris,
it made me "hmmmm..." too.
As far as the function is a disfunction
, i can't say how a reference point will look like...
I thought it would be the same as a reference point in 3D, only in 2D (sketch).
...and maybe this point will not be moveable with the mouse during working on scriptmade sketches to be able to set an anchor for dimesioning this sketches.
and yes, Chris, i think it's one for Mr.Andy, too.
except somebody else has a good idea or an trick...
Regards
Stefan
