Subd Join in Rhino common for radial symmetry

[leex]

Well yes, noticed before.
!_Reflect breaks the topology, when cuts with a plane along the axis.
May be (I hope) !_Reflect is a temporary solution
It needs mirror and join only, without splitting.

SubD Symmetry?

Hi Brian If the points of mother side are moved to the left outside the axis , then the topology breaks Reflect. [Reflect] The same actions but in the T-Splines. First, both sides are interdependent. Secondly, the topology does not break (The axis of symmetry is partially frozen) Third, another positive is that the geometry on the opposite side is changing in real time. TS Symmetry [TS Symmetry]
