I’m using Blender 2.82 and I was following Blender Guru’s tutorial about making the drooping icing on donut.
I thought I had followed every steps, but when it comes to pulling the icing vertices down., I managed to pull all the vertices down together. The vertices were not snapped to the mesh. Please kindly advise,
Not sure I quite understand - but I’m guessing it’s because you have proportional editing on. Press O to toggle it on or off. Or referring to your images above (the last one), click on the little circle target shape next to the snapping panel.
The white circle is the proportional editing’s area of influence. Just use the mouse wheel to make that area of influence smaller when you pull it down.
