Carport / canopy roof

Hi
A friend wanted me to do a calculation on a carport and a canopy roof.
I tried to create a room and cut out the walls, but did not works so well.
Then I tried create 6 pillars, but I could not get the roof on it as it got greyed out.
The canopy roof I'm unsure how to do it.

So, what is the best way to design a carport and a canopy roof in Dialux?.

Thank you

Sincerely
Thomas
