In my curve fitting experiments described previously, I had tried the JOIN and MERGE options.
Now Rhino is merging and joining on every match command. I can uncheck the MERGE option by setting CURVATURE, Unchecking MERGE, then setting POSITION.
Even when unchecked, MATCH is joining everything.
I cannot give exact steps to reproduce because I cannot get out of this. Even restarting RHINO does not make it go away. However, I presume it occurred by doing a match with MERGE or JOIN set.
Any ideas on how to get out of this predicament?
