Perimeter of Tributary Area

Hi,

I have developed a GH plug-in that outputs multiple tributary areas of an irregular geometric shape. Now I would like to find the perimeter of each tributary area within the geometric shape, but I wasn't able to figure that out. The tributary area surface created by GH doesn't have defined boundaries and thus I can't select the edges of the computed tributary area.

Find attached picture.

Thank you

(...) doesn't have defined boundaries (...)

how is that?

The colored surfaces, as seen in the picture, created by GH are not layers that I can measure the perimeter of. There is nothing I can "snap" to measure the edge distance.

To receive help, you should make it easy for others to understand your problem. If you have made these surfaces in GH (looks like a voronoi, right?), you have some type of data (curves, surfaces, breps...). Why you can not measure the perimeter? What type of data is?

this is your 3rd thread with the same subject...

However, if your "multiple tributary areas" are surfaces you can try this one:

Thank you for your help. Your method does work for surfaces, however since the tributary areas computed from grasshopper are not surfaces, I was not able to select them as an input criteria.

ok, then you may tell us what kind of objects you have. Dogs, cats or maybe meshes?

for meshes you can do something like this:

But however, without a example no one can tell you what to do...
