I am new to blender and I am trying to extrude and bring down the dribbling parts of frosting on a donut, but when I bring the vertices down, they cut into the donut as shown (picture is taken from inside the donut).
I have proportional editing on, the snap to face tool (with project individual elements), and I even tried using ctrl button when dragging down vertices (I saw someone say that can help it to not show through - I'm not sure the reasoning of why it can work - it worked well with grabbing vertices but not extruding them for me) However, the frosting still pierces the donut - Is this normal and I shouldn't worry about it, or am I doing something incorrectly?
I appreciate any answers - Thank you!]1
