you might see it..

If you add a pond or puddle in the foreground  that reflects it

These are the details that astound the casual observer

Or, put it

on a portion of the layout that's near eye-level.  If you're looking in from the end of the building, trying to bring the passenger train to a halt at the right point, you'll see all of that detail.  Looking from above, I agree, it would be a waste.

But I suspect you're so far down the rabbit hole on your layout, you can't just move the location.  Too bad - can you make it a flip-top, to open for show?  I'm thinking of layout buildings on display that often have elements removed during tours.  For ops, you could leave the lid closed, but for show-and-tells, you could open it up.

Internal strength might be improved with ribbing

Looking at it, I'm assuming the "good" side of the print will be the outside "top" of the roof and printing will begin at the outside eaves of the roof and the bottom crossmembers of the trusses.  The trusses will add strength and help support the roof as it's printed, but the internal spaces of the trusses themselves might wind up needing some smaller supports.  Would it make sense to model at least some of the center trusses as solid ribs?  Or perhaps include a very thin solid film in the trusses that can be cut out like flash after cleaning but before curing?

I haven't tried to produce a large piece like that yet. Most of my prints have been smaller parts, the largest being a 20 foot container in 1/87.  I have had a few issues with long thin walls in attempted 40 foot containers flexing a bit when not properly supported at relatively close intervals.  

I think that some of the support structures that result from those hollow containers could probably be used as scaffolding around a construction site with a bit of pruning.

It is not that big,  I think

It is not that big,  I think you are over estimating the size of the part. 

This is not an big deal to print.

It is the roof for the SONOR MEXICAN MARKET / THRIFT STORE

Overestimating the size? Probably...

I tend to think of stuff in terms of 1/87 rather than 1/160, so I unconsciously doubled the size.

Will be interested in hearing how you went about it, in any case.

Have you thought about 3D printing the two "Thrift Store" signs?  The raised lettering would look sharp.

I will be making Decals for

I will be making Decals for the Mexican Market,  That is what it has been for as long as I can remember.  The Thrift Store is after Sept of 1996.  Yuk!

The sign is a sheet of 4x8 plywood of some sort 7.62mm x 15.24mm.  the lettering would be small can be done but I think a decal with a little shadow effect will give the same results if need and much simpler to do for the modeler

Unless your layout is completely finished

and you are bored with nothing to do I would consider this a waste of time.  No one but you will know its there and we will have forgotten this post,  like most others from the past.  Why don't you just make some quick solid supports and leave the roof loose on the walls.  That way you can go back at any time and add these fancy trusses.  Give yourself some time to think about it and maybe in the future you'll discover a easier way to make them.  Just my 2 cents.

I really enjoy projects like that and applaud your efforts. It doesn't matter if it will show or not. It's a challenge and well worth the effort. 

The person that I'm making

The person that I'm making and selling the kits to will know it is their when they build it. 

It shows that I paid attention to the building in question for them.

Much like under body detail or interiors for passenger cars and caboose,  No one knows it is their other than the person who buys and builds the kits will appreciate it and see it.

I have built many Airplane, Military and Car models over the years for museums and clients.   Just do to the fact the Bomb Bay was closed and no one could see inside, does not mean it was not built authentically for the client.  If they wanted me to build them a 1:12 1967 Mustang coup I would make sure it was as perfect as I could get it.  I know that the hood and trunk will be glued down and never opened., but I still put in the trunk mat and spare tire and jack.  I know no one will ever see the engine under the hood but I still install the engine into the car run the 8 spark plug wires and properly detail the engine bay.

It's about giving a client a little more than they expect and in N scale it is hard to do.

It is all ready done took my about 30 minutes,  did you not see the 3D render...?

Orientation

If its possible to orient it on its end, like stand it up on the build plate, you wouldnt need any supports.

SO SORRY

I totally glossed over the mention in your first post that you were building this structure fo someone else.  All of my comments, which don't mean a damn, were in regard to you making this for your layout.  By all means, for someone else, definitely make it the way they would like it to be, and/or put all your heart and best ideas into it for it will go into the world with your name on it for all to see.

I’ve built a few barrel roof buildings

And most of them will never be seen inside, but I’d love to have a support structure, and I’d find a way to showcase it. Even if it’s not going to be seen on this building, learning the skill can definitely pay off down the road. The market you are building is a cool building to model.

Slick use of the trusses.

Greg Amer,

two other buildings I have on the list to do next,  looks close to yours.
