Irregular column plan

[TomasoCardia]

Hi all, 

How can I do to actualize my column to the reality ? The green line rapresent  the reality of the column.

How can I draw a different plant for my column? 

( Yet I have tried to change the profileof the singular pilar but cannot did it)

Your illustration is very hard to conceive. The green lines are crossing themselves and not enclosed to form a profile. And which ones of the black lines are your column?

Do you mean changing size of your column family? Making column parametric?

To change your column - click on edit, Edit Family. When you are in Edit Type click Duplicate and then you can tweak your column the way that you want. 

In absence of more clarity regarding your situation, this is all the advice that I can offer. Better pictures, or probably a file, would be helpful.
