You have a geometry issue there. I would use the traditional solution which is done to address just this issue.

There is also the traditional (classical) rake detail like this...

Keep in mind though that to make a proper miter requires that the rake molding profile is different from the crown molding profile.

Take a look at OBJECTiVE. It's quite effective for this kind of exercise - you can see some examples and a discussion related to this here.

I've handled a similar situation by using SEO to create an intersection of the beams at the corner. The rest of the trim is handled as you have it. So you end up using 4 beams instead of 2. It's a little complex and requires some SEO gymnastic. I'm not 100% sure that it'd work in this situation.

The trims I used on my cornice do require SEOs to make the vertical miter. The default intersection in this case is not vertical. I had to run the moldings past each other and use a couple of slabs to make the cuts.

Get rid of the gutter. You don't need it.

Is this what you want to do?

There is never only one way to skin a cat.

How you model anything depends on what you want to do with it.
Do you need it to show up in your schedules correctly? What kind of info do you want to extract from it, does it need to look good in a floor plan and in 3d or is this just something for makeing a 3d view??

You can model the fascia and trim with roofs, rafters, slabs, mesh, .gsm,

For modeling the fascia and trim I typically use roofs. I drag a copy of the roof over 1 1/2", split and delete the part I don't want. Then change the depth of the 1 1/2" wide roof to 5 1/2" deep. Now its my subfascia. I drag a copy of the subfascia over, split it down to 5/4", change it to 7 1/4" deep and thats my fascia. Do the same for the drip edge and trim, and so on...
I use a roofs for the fascia, subfascia, and drip edge of the level edge of the roof also so everything cleans up very well.

There are more ways to do this than I care to describe.

My advise no matter what method you use is to model it just like you would build it, and in the same order it will be constructed in.

Nice detail Steve. Clean and attractive without the fussiness of special rake moldings.

Giuseppe,

To model it like that isn't too hard but involves a few tricks with SEOs etc. Here is a pic of a quick example I just threw together. Please excuse the cr*p rendering. I just used the AC14 defaults.

...and since I don't have time to explain the details, here is a module of the dormers to play with. It's all default ArchiCAD 14 (US) except for the crown molding profile which I just grabbed from an old project.
