Finding Perimeter of a Tributary Area

I used the Grasshopper plug-in in Rhino to find the tributary areas of points laying in an enclosed boundary line. Now, Grasshopper outputs and displays the tributary areas of the shape through the "visual tributary area" output command (Please see the attached screenshots for clarification). I would like to find the perimeter of those tributary areas outputted by grasshopper, but since the tributary areas created are not meshes or a tangible surface, I cannot select its boundaries to find the perimeter of the tributary areas. (Please find the attached screenshots for clarification).

Thank you.

Hello OH,

is this post any different from these 1 2 3 you already have posted?

It is not, but none of the suggested methods were actually beneficial to my problem inquiry. Hence, I posted it again with screenshoots and more clarifications.

I see, though some things are not clarified.

which plugin are you using? i don't think anyone can tell the outputs just from a screenshot.

if we know the plugin, so we can download it, why not upload your definition?

what is the TribM output?

if those tributary areas are not meshes or surfaces, what are they? floating numbers? preview colors?

finally why post those clarifications to a new thread instead of the existing one? this would make the forum users life a lot easier, when they are about to help.

i am pretty sure these have been asked in your previous posts (did not check em)
