"Pivoting" a part while moving faces Still a newbie to Blender. Trying to line the gray tube along the edge of the blue object, but there is still a slight lip. How do I rotate or pivot or whatever the gray tube so that it follows the edge of the blue object?
This may not apply in your case, but it would be much easier to copy than to follow:




Select the perimeter of your shape
ShiftD duplicate it and P part it off into a new object
Header Menu > Object > Convert to > Curve
Adjust the curve's bevel in its Data tab > Geometry panel


Convert back to mesh if necessary.
