Hello, I'd like to ask how do I create purlin connection the type of such in the picture:

My beam and purlin are these: http://www.fotosik.pl/pokaz_obrazek/31cbe88aecff9624.html

As you can see first of all there is no off-set. Will makro create off-set or do I have to make it somehow before creating component connection itself?
