I made a gun scope, and I need to add some edge loop for sharpen edge while applying subdivision modifier.
But problem is, you saw the picture, edge isn't connected, so I can't add edge loops anymore.
I don't know what causes this, but sometimes it occurs and this is not a first time.
I want to know why this happening, and also want to know how to fix this.
Anyone if knows about this, please give me some advice.
