eave

[Seena Hassouna]

So,

I have a building with 11 7/8" TJI's as the roof members but we want to use 2x8 outlookers as the eave. How do you suggest doing this. Using chain extrude or making the roof thinner. I'm a bit concerned about the latter cuz of bearing height accuracy.

Thanks,

Seena

Hi Seena, For me it would depend on whether I was doing design docs (eg for presentation) or WD's. For designing it is pretty fast to use two roofs. The first one would be as thick as the 11 7/8 plus your sheathing and would have zero overhang. Then I would duplicate that in place, change the thickness to 7 1/4 plus sheathing, go to an elev. view and move it up to be exactly even with the top of the first roof, and then add overhangs. For WD's I would probablr either just draw it in section (2d) or I would draw the profile of each member and then extrude to 1 1/2", go to a top view and duplicate every 24" (or whatever) then create a "skin" which could be a very thin roof or just another extrude.

Thanks Peter,

I'll probably use your first suggestion. I was hoping there was a cleaner way.
