Hi,I would like to know if there function like array,unction which allow you to follow up any kind of line, and not only determine by circle or square.Thank you very much,

I'm not sure I understand your question.  Have you tried the Measure or Divide commands?  They work best if you use the Block option.

Let me explain you in a example.  Lets say I have a column, I want the Column to follow up a wavy curve every 7" gap, or have this column double few time with even gaps follow by the curve line. How do I do that? 

For the first task try the Measure command.  As for the second I have no idea.
