Hello,
I am a beginner in Grasshopper, took a class a few years ago in Parametrics, but wanted to brush up my skills so I created a small project for me to do. and I found this dope script on youtube, but now Im very confused.
Could someone explain why if i build the extruded surface on grasshopper the point will formulate using PointInBrep. But if I assign a polysurface made in rhno as a Brep the points wont formulate? I dont get the concept of why it wont pick the points inside the brep.
you don’t see the points because -as they are contained inside the Brep- maybe they are not in sight?
please post your GH file with internalised geometries
@inno
Thank you for your response but could you clarify what you mean by contained in the Brep. Because when the script is connected to an extruded surface on grasshopper the point would formulate to the points inside the surface. But when I assign the Brep to a polysurface made in rhino it will not formulate.
for each of your Points, the Point in Brep component will give you a True/False boolean indicating if the point lies inside the Brep (True) or outside the Brep (False)
Point in Brep component does not care if your Brep is open or not: an open Brep can’t of course contain any point, so it will spit all False values for each point, which means that Cull Pattern will delete all your points if the Brep is not closed, you’ll just end up with an empty list
this said, it’s pretty difficult to make assumptions based on text, if you want to understand what is going on you’ll need to post a file with internalized geometries
