In the attached pic I don't get green highlighting on the join component, seems like it's broke. Also in the pic I think that the join should be placed before the fillets logically but that results in nothing being produced but no errors reported either.
In Rhino, selected objects are given special treatment in the viewports. This is something I haven't done yet for Grasshopper (but probably should). We'll need to rethink the whole display pretty soon. It has to be more customizable and preferably a lot faster too.
Thanks for the replies. In this case it wasn't working, seems like my computer and or GH didn't connect. I exited rhino re-opened rhino and GH works as expected.
