Unable to join surfaces generated with SWEEP1 that share the same edge

DUPLICATE THREAD? Looks like several related threads could have been avoided:

Solids from surfaces - boundary or join

still having a problem with joining BREPs in more complex situations. See example attached and let me know if you know what i’m doing wrong. When i bake the surfaces they are not joined in Rhino, which prevents me from continuing with the project in GH. What puzzles me is that the center surface shares edges with the other two so should be able to join but doesn’t. Thanks. [image] SWEEP1.gh (9.5 KB)
