Sorry for the extra scribble marks in the picture, this is what I'm trying to due with HD Pro 2018. The picture is of one section of wall, two stories. It has a footing that the rebar is .30cm X .90cm. A Cap for the first level / Footing for the second level that is .40cm X .15cm, this is what the floor for the second level is connected to. Then it has a Cap for the second level that is .30cm X .15cm. Finely we have the Column that are .40cm X .40cm roughly 3 meters apart and on each outside corner and will also be placed on the inside walls for load bearing walls. How would you go about doing this? Column are kicking my butt, it would be nice if in the wall information display would ask you if you would like columns in it and how far apart!
