This one's got me stumped. How can I create a roof profile to look like this beam? I have the same deflection numbers and same width/height on the beam and the convex roof profile. 

 

The contractor purchased some old arched beams on an auction.

 

Thanks in advance!

You need to set the overall width of the arch (roof profile) to be slightly less than the span from the wall/beam to the ridge of the roof so it ends up pointed at the top. It will be a bit of trial and error. Or, if you didn't already try it, you can trace the top of the arched beam you show and save that as a roof profile.

I didn't realize how easily you can draw your own profiles!

Thanks Mark.

I think they'll like it! Any quick tips on getting the soffit/fascia to stop as it would? Not a big deal though.Attached File  barn.jpg   110.77KB   4 downloads

That is looking good. It might work to change the depth of your overhangs on the eaves or cut the roof at the edge where you want the soffit and fascia to end, but most likely it will not do what you want. It may be best to draw a ceiling with the similar method for the roof profile and then draw a solid polygon or beams to use for the fascia. It sometimes is better for control and much faster than the trial and error with roof holes and adjustments.

It is looking really good. 

 

Instead of running the arched roof down to the same wall height as the sides, maybe set it on a taller wall or higher beam that matches with the top of the intersecting roofs on the sides?

Brent,

 

The arched roof does actually sit on a beam with a top height 2' higher than the sidewalls of the lean-tos.

You may need to reduce the 'Top to Fascia' for the arched roof to 0.000" ?

 I know this is off topic so perhaps Derk you can message me separately but I just had a potential customer come to me regarding steel trusses he got and wanted to use them in a house design.  I told him to first get them inspected for structural stability before I could even start to talk about design.  Not putting my name on a used product and think I am okay with that with EOI.  Curious if you are doing same or how you approached it for your situation.  Its a same because the proposed project would really look great.
