Measure interior angles of a polyline and cull segments

[rteuman]

Hello All,

I’m trying to write a script that will measure the interior angles of a polyline, here’s what I got so far: (combined some scripts I found on the forum)

as you see it’s measuring some of the exterior angles at the moment:

but I need to get these instead:

Then, I need to sort these curves. The ones with the interior angle that is more than 180 will be in a different group (highlihgted with red and blue here)

here’s the GH file with internalised data:

Thank you!

I knew I had this one before !

How to compute the angle between points in the same direction?

Hi, A very simple way to get oriented angles is to provide a plane to the Angle component. In addition to that, assuming what you are after is the dimension display, you need to test if the value is below or above 180° and flip the dimension if necessary. [image] Angle Dimension.gh (12.7 KB)

Hi Kim, you can make it simpler
