I’ve got this problem with SubD reflection option when I want to reflect any surface, I do it somehow by luck (mirror is easier since it has preview) and finally I’ve made it. but when I extend, it splits up. Please assist me to understand the problem. I appreciate it.

Not sure how you exactly extruded that, but you have some overlapping geometry. I think you may have made a poor selection when starting to extrude, and did it several times.

Remove the extruded part, including the extra two faces and extrude again:

\_SelEdgeRing on bottom and top

Delete the selection

Sub-object select the two faces (ctrl+shift+click or cmd+shift+click)

Thanks JesterKing. That’s really helpful. I don’t know how I came up with that (out-of-shape) shape, but I’ll try what you’ve just told me. I’ll try to make it following your steps. Please give me the credit to get back and ask if in case I couldn’t make it. Thanks!
