Perimeter of Head

Hallo there…
i need help. I have to count the perimeter of a head (a head of a figure - look at attachment).



i’m beginner in blender. do i should make a new edge loop? or is there another idea?
help :frowning:
Thanks before for answering!

there are some script that can calculate the lenght of a line or curve!

but for now might be broken because of Bmesh!

should be back soon i hope

but you can check the lenght of each edge segment in the N panel
and manually add the lenght!

salutations
