Hi guys, Assume I have a component requiring an point input, P0. Now based on the input point P0, I have create a solid square as the output of this component. How could I choose a vertex point on this square as input parameter for my grasshopper component again? I know I can bake the grasshopper c…

Do you have a file to demonstrate what it is you want to do?

Hi Thank you for your reply. Attached is the image showing the brep I have created, now I want to use the two points (marked as red circle) as reference. It can be also other two or three points. Regards John [rhino grasshopper]

Thank you for your reply. Deconstruct Brep is not a solution for me as I need to let choose specific pair of points, not all the points at once. Regards John

no, .gh file needs my component which is under dev. My problem is just how to use the two points on the brep which is output of my component without baking. John

If you’re building this brep with a component that you have coded, you should be able to get these vertices with the code in your component (get Brep.Vertices, sort accordingly, and take the first or last 2). Similar workflow with grasshopper components: [240624_get_points] -Kevin

thank your guys for the response. This is not what I intend to do. When you have created a solid box, user should be able to pick the two or three vertex and use them as the input parameter to the next component. I don’t know which two, three or four vertex user want, but should be any vertex, but …

No. Look at Deconstruct Brep.

3. Attach minimal versions of all the relevant files
