Please see what I wrote above, that should at least get you started. This can all be done with 3 basic or out-of-the-box nodes, all of which I have mentioned in this:
If that still isn’t enough, let’s try troubleshooting it together. You said previously that you found the
Select Face node.
Good, that’s a great start, as it gets you the face you want super easily. When you use that node, you will notice that the output is a surface. Well, what can you do with surfaces? Let’s find out together!
Turns out there are a lot of things you can do with surfaces. Let’s look for something relevant. Remember, we want some way to get the perimeter edges or lines, as those lines will contain the points we need.
See anything yet? Wait, what’s that?
There is a node that mentions perimeter! Let’s take a closer look.
Darn, the outputs are curves, not lines. Wait, I remember from the Primer
that lines are curves! Awesome, that sounds super relevant! The output are curves but we need points. More specifically, we want the end points. Huh, I wonder if there are any nodes that takes curves as the input and outputs a point, specifically at the end of the curve. Should we check?
There is! Wow, we are almost there, now we just need to plug the nodes together.
Tadah! We did it! High-fives all around!
