It works here under Windows with both Python as well as Vb. It’s possible that the version of rhinoscriptsyntax installed on Mac is older than the one on Windows, maybe a bug was fixed in between. I don’t have my Mac with me today to test…
Yes, that is probably it… It’s actually me that reported the bug here
it’s not a huge deal though i am working on something which has a few of these in there… shouldn’t be too bad to change once i figure out the AddLeader oddity… (it’s not bad because the duplicate point isn’t being place in the model… still only two points there)
but if you remember, can you test this out when you get back to a mac?
edit- just saw your edit.
seems likely it’s a mac thing then… the service updates are usually a month or two behind and maybe even more with python.
The Mac build may be a little behind at the moment. This should resolve itself soon though since I’ve got some python/Mac work coming up right after I finish my current project.
