Just noticed that the LoftSubD and SweepSubD commands aren’t working in the newest Beta. v9.0.26209.18304 Tahoe 26.5.1 The help panel shows access denied for these commands as well. I tested the same geometry in rhino 8 and that works fine there.

RH-97353 is fixed in Rhino BETA

Tracked here: RH-97353 LoftSubD, Sweep1SubD, Sweep2SubD: broke with renaming

LoftSubD / Sweeps not working

LoftSubD not working as expected in V9 Beta was previously reported in Sub-D loft not working (but works on same model in 8)
