When I extrude faces in Maya LT with symmetry, this happends:
You see where the faces make a hole.
I tried with “Keep faces together” on and off, but that didnt change anything. What kan I do to avoid this?
Are you using symmetry from the Modelling Toolkit panel?
I had a go at doing basically the same thing as you, it worked fine for me though.
Create a new box and try extruding with symmetry on it. You might have pushed extrude multiple times by accident or something.
Using the extrudetool in the modeling-toolkit fixed it, thanks
