I just encountered a very basic problem, but I haven't figured it out. I hope to get some detailed explanations. When I use the ‘fuse‘ function to connect a curve end to end in Houdini, I find that the number of points in my viewport and spreadsheet has changed. However, when I try to store these points in a list with the primtpoints() function, I access the len of the list. I find that the len here is still the number of points before ’fuse‘. Why is this?
I’ll appreciate any suggestion.

Hi,

That's because your vertex count doesn't change, and primpoints returns the points used by the vertices of the primitive.

So before fuse it would be:


after fuse it would be:

Oh, so that's it. Thank you so much.
