Hi, I was trying to model a dimple in a couch upholstery and I created the following simple shape representing 1/4 of what I want, using 7 vertices:
As you can see, applying subdivision breaks. The center vertex is pulled down towards the lower one of there is an edge there. I need that edge so that I can chamfer a fold in the fabric. The screenshot isn’t obvious so I’ve attached my blender file. Thanks for any help you can give me to correct this issue.
