Roof Eave

[OBERMEYER]

Roof eaves generate odd 'flange' geometry at corners. See image. How do most users work with this condition? Model morphs and use SEO to remove? (seems awful time consuming)

Not to compare but Revit, as far as I know, does not generate this condition at corners.

Perhaps there is a way to clean it up by applying a fascia profile that trims the unwanted flange via material priority? I haven't tried that yet, still learning to work with profiles...

Is it because the edges of your roof are set to different angles?

Maybe you can help me understand why my inclined beams wont meet properly...

This happens sometimes and I'm never sure why. Same junction order, same material, same layer, reference lines meeting.

Whats happening to make them not want to join neatly??

thanks

The ends of the beam reference lines look like they join so the beams should trim to an apex - they do when I model them.
But it looks as if you have something else cutting the bottom of the beams - maybe that is interfering with the connection?

Drag a copy of just the 2 beams away and then see if they trim.
If not select them in plan then FILE menu > External Content > Save selection as module.
Zip that .MOD file and attach it to the post here.

Beams have junction order (in Model panel), change the 2 beams to have the same - something different than what it is currently (for example a higher number). So they have priority to join before any other Beam in the intersection.

Might help also.

You ar eright that its the beam underneath that is causing the problem. When I move the rafters away from this beam they trim correctly.

Ive tried changing the junction order values for the beams in every combination possible including the beam underneath, but it has no effect.
What is even more strange is that there are 2 identical beams just next to these ones that trim correctly.

I could get Junction Order working by splitting the ridge beam at the intersection of the angled beams (so 4 beam nodes join at 1 point in plan), this works better than the previous T type junction.

But I realise may not be the best solution, because you'll be splitting the ridge beam at every intersection (and there seems quite a few).

Thanks James, in fact I found the solution was to change the junction group number in the layers settings so that the beams that I dont want to interact are in separate junction groups.
