Hey, Everyone, I have been digging through old topics for a while now and am still having a few issues dealing with rotating families to be perpendicular to a surface or curve. Here is what I have so far. ###This [image] ##Yields this [image] For some, it is working, but it is a hit or miss. …

Thanks! Let me check it out for my use case.

Hello John, seems like we all struggled when doing this haha This is my approach : [image] [image]

Thanks everyone! Will try these shortly Got something else right now. :slight_smile:

hi all I have tried your resources, I find this to be very good, but one thing is that I want to control the distance between families or the number of them, what do I do here? thanks you Array curve.dyn (43.5 KB)

@khuvv.hp , can you go ahead and open a new topic with any screenshots that may help answer your question.

I created a new topic but no one helped me, Can you hlep me?
