I have a tablet/pill shape, and I want to select all the outer vertices or edges, and have them stay where they are, so that when I do a proportional edit, they remain fixed, and so the edges/vertices are stretched rather than move around.
This is the effect I am trying to get - a bulge in the dark meshed areas https://imgur.com/a/qgCjXm5
If I use proportional editing, it alters the edges also.
So is there anyway of selecting the outer vertices, make them stick?
I have tried to create a vertex group, and assign a weight but it hasnt worked yet. https://imgur.com/oF4xY2B
