First I want to say thank you for all of your prompt replies.
I may misinform my intention on what I wanted so I thought maybe this time I can be a little clearer, I hope. I created a new post because I don't think I can do an attachment in my previous post.
If you take a look at the attachment this time you will see what I was aiming for. Its a flat 3 sided star. I created one side and instance it because if I want to change any point it will reflect opposite points as well.
With the attachment when I select all and do a Attach Curves|Connect, it only attach 2 instead of 3. I'm not sure what I'm doing wrong. Can you guys detect my error?
