Need advice on SubD modeling

This watch strap is my first SubD model, please advise if I am doing the strap in the right way or not. Thank you.

Looks fine to me. Is there something you don’t like?
Many roads lead to Rome!

I am not sure the tip should be modeled like that, and not sure the stitch line should be done that way, as the tip part looks like a mess?

regarding subD it s always important to check the positions of star-points (vertices, that don t have 4 Faces) . (and non-quads / n-gons (= faces with 5 or more corners))

to have nice control over edges - best approach is to have a faceloop / stripe of faces along the edge.

with this in mind - i suggest the following 2 improvements:
(bottom = original, top = suggestion)

and my guess is, that you might get the same shape with less faces…
check (this forum or google…) for “subdivision modeling typology”


Thanks for the suggestion, is there a command or method to create faceloop / stripe of face along the edge? Or do I need to manipulate manually?

there is no single command (or at least i do not know it)
I mainly used
_extrudeSubD (starting with an edgeloop)

other commands you should have a look at:



for subD also gumball is super powerful.

check the forum or the mcneel resources for tutorials … you ll find a lot of very nice stuff / videos / …
