SubD Symmetry?

I guess. But what I really want to know is, does “join” work for subD in rhino common for the current WIP, and if so, does that mean that someone with more advanced skills than me could make a SubD Join component easily?

A subD join component seems like it would be very powerful.

I have played around with a workaround for this that’s almost (but not quite) glitch-free and it was very very fun. It’s tedious but basically, drawing planar NURBs surfaces, running them through this, joining the meshes and then converting to SubD was possible. And that meant inserting rotations and/or mirrors after the conversion to mesh and before joining meshes was possible. And that yielded some very smooth and pretty surface textures.
