Create Points from Top Center of 3D Solid

#1

Is there a way to obtain x,y,z values from only the center point of the top of a 3d solid? I see the Solid.Centroid, but want the top and not the middle of the geometry. I have a ton of 3D Solids in my drawing.

Any help would be greatly appreciated!

Thanks

How about try extracting the surface points at the 0.5 parameter for X,Y and filter by surface normals?

Or take the results of the Surface.PointAtParameter into a List.SortByKey where the key is Point.Z, and then a List.LastItem.

Thanks @Ewan_Opie and @JacobSmall! I’m finally getting back around to this one. Probably pretty basic question here, but I not seeing the answer in my searches. How do i go about extracting just 1 point from each list to create my points from (see screenshot example below). Ultimately, I want to create aCapture point from just the top center of the solid, not all points.

Thanks for the help!

In the method I describe, the surface normal Vector ( The “I’m facing this way”) is sorted to find the one which has a positive Z axis value (“I’m looking up, so I must be on top”)

Thanks @Ewan_Opie! I attempted your solution earlier, but just realized that I didn’t have the Level 2 set on the sort and last item list. Setting it to Level 2 worked like a charm! Appreciate all the help!

Thanks
