SubD extrude face using the gumball fails when single vertex resides on the reflection plane. See images below. File attached. I’m running on 7.0.20154.14355.
I understand this extrude operation creates a potentially weird vertex condition. Is this to be expected? SubD should be able to handle this situation, I would think.

Same here. Only with gumball extrude. Regular SubD extrude works.
Interesting. If I extrude by typing the command, the face extrudes, however, I don’t get a reflection and the model becomes uneven. Next,If I modify the model in any way, the previously extruded face breaks…but at least becomes symmetrical again.
can you post that model please?
@theoutside, It’s attached to my initial post.
inset works, as does a ctrl+scale to create an inset face…I’ll write it up!
Upon extruding this face again by using the _ExtrudeSubD command and toggling to SubD Flat Display, you can see that this edge rides right along the reflection plane.
Next, if I select this vertex and slightly move it so the edge no longer rides parallel on the reflection plane, its fixed.
yep- I’m seeing the same thing. we’ll dig into it!
RH-59020 is fixed in the latest WIP
Hi, @theoutside. The SubD becomes non-manifold in this situation.
I reopened the bug report with this example.
