Check Pufferfish Scale to Area component that will let you do this uniformly or even non-uniformly. (13.6 KB)


thanks for your response, actually i have a semi- spherical shape, when i use “surface command”, i can’t set my model…
another one instead of surface i used “brep”
however i didn’t see any change in the value of area.

i have a model, like below
unfortunately i cant do what you said

i cant choose “sur command”

unfortunately when i open your in canvas,
i cant see one of your command, in my pc.
do u have any idea please?

Yes, i installed.


You definitely didn’t install correctly. Do you know how to install plugins? Did you read the instructions text file that comes with the download? Did you unblock the file? Do you see any messages when opening Grasshopper? Do you have a Pufferfish tab in Grasshopper?
