Tunni lines control node

Hello, I am trying to figure out how to have access to this view mode (attached image) where a control node can manipulate two handles along. The Supertool keeps crashing my session, unfortunately, and show Tunni lines is greyed out in the menu. Thanks for any tips!

I think what you’re looking at may be a quadratic off-curve point rather than a Tunni control node.
I don’t use the Supertool stuff, but I wonder if converting your paths to cubic would enable the interface you’re seeking.

That was it! Thank you
