I am new to blender, and I am looking to inflate the geometry of an artery like a balloon.
I have used the shrink/fatten tool and it produces the outcome I desired except for the inlet and outlets. I want the artery model to be considered a shell, and if we imagine that the inlet and all the outlets are fixed, I would like the shell to simply expand a percentage, maintaining the original positions of the inlet and outlets.
I hope the images help to display my problem, yet if I haven't been very clear, I will try to explain better. Thank you in advance for the help.
