Railing baluster problem

[Carlos GT]

I am trying to create a new type of railing. I created different famylies for the balusters and posts. The problem is when I visualize the railing the new balusters fell inside the new posts, in the corners looks like the baluster and the post were one object.
What can I do to solve this?

Thanks.

Can you post and example please?

I think the problem is how do I control the distance between the post and the balusters at the end, corners and the begining. Right now the ballusters overlap in the posts.

I appreciate your help.
