roof edge problems

rgarand — Tue, 23 May 2023 13:42:01 GMT

Hello everyone,

I have a small problem with my roof edge angle. I have attached a an isometric view. As you can see the fascia does not connect to the other fascia. I have created a roof with a perpendicular roof edge angle. My soffits are not cleaning up the way I want either. I do, however, understand why the images are like they are...yet they do not come out the way I would like them. The images attached show the soffits after "trim to roof".

I have tried to extend(overlap) the 2 roofs so that the soffits clean up...but this does not produce the corrct outcome either.

Any help would be appreciated.

Hi,

1st' -The roof edge angle is perpendicular on the roof plane, you have to make it (on the ridge's side) to be vertical, to connect the roofs
2nd' -You can trim that parts selecting the two roof planes and the outstanding part of that wall then use the command trim to roof

Hi Ede,

"1st' -The roof edge angle is perpendicular on the roof plane, you have to make it (on the ridge's side) to be vertical, to connect the roofs "

but this is the roof edge angle I would like to use for my building...I would hope to be able to do this. This is where my problem is...

Thanks for the tip on roof trimming though

Hi,

You can use the perpendicular roof edge, you have to change the edge angle to vertical only on the sides you connect the two(three) roof planes

Hi Robert,

please see the attached image... I believe it shows what you're looking for.

............or you can select both roofs at once, with the roof tool active, click on the edge intersection of both roofs and select vertical. Double your pleasure. 2, 2 roofs in one move!

Jeff,

I tried your tip...and did not work for the valley condition that I have. What I think is happening is that the top of the valley is what controls the extents of the roof.

I have created the condition in autocad...that is my background, 18+ years worth. See the attached pic

Hi Robert,

So your last attachment was an AutoCAD product? I have attached the a similar product from ArchiCAD, [sorry about the hip / valley mix up].

Are you using the miter feature of the roof tool? They need to be mitered properly to enable the miter dialog box feature. This is probably the single feature that sold me on ArchiCAD over Vectorwoks.

Page 98, volume 1 of the user manual. The same principals work in valley, hip conditions.

if your roofs are grouped you need to suspend groups for any of these operations to work

Jeff,

That was it. Thanks for the help!

Robert,

Glad to help, or pass it on is more like it. The give away on a good miter/roof joint is that untrimmed wall, roof, column......or even the smallest sliver of it. That feature is worth it's weight in gold!

The final product...This roof has a perpendicular roof edge. The valley intersection as well as the ridge intersections needed to be mitered to appear and function properly. The Soffit/fascia is just a wall, trimmed to roof. We will detail it later in the large scale details.

Thanks for everyone input on this one.
