Create Roof

[jmartinarch]

I have a fairly simple shaped floor plan that I tried applying the AEC>create roof command to and received the warning that the geometry was too complex.

So I divided the roof into 2 parts by creating 2 rectangles and then generated a roof over each one. Is it possible to merge the two roofs?

If you Ungroup one (or both) of the Roof objects, you'll end up with a bunch of Roof Faces. You can then Add/subtract Surface from any Roof Face to create what you want. Of course when you Ungroup you lose the parametric capabilities of a Roof. But FWIW, I almost always end up with Roof Faces because I actually prefer them at/after a certain point in a project.

I'm a bit surprised you got the warning.

Did you nominate a hipped roof at the start? Maybe it would have worked if you had started with gables and then added the hips.

On another note, do you want the wall lines showing across internal doors? Maybe you have a Ceiling class turned on.

Hi,

See Attached, No error in creating and I Clipped surface rather than create solid because this way you keep the roof object rather then losing it by creating a solid.

This is the roof plan I wanted. I deleted what I had done before and did it over. The second time it worked.

Question: In edit roof settings, what is the 'Bearing Height' a reference to? The floor immediately below the roof or what. If so, why in layer settings can you set the elevation for a roof? There are so many dang places to input a wall height, a layer elevation a story height a bearing height....

My hat is off to those of you that have figured it all out and can produce nice elevations and sections.

The bearing height is the height of the roof - at the line you draw to indicate slope - above the layer height that it is placed in.

I find it useful to have roofs on their own layer. Then it's a fielder's choice situation to set the roof layer height to the plate height for that story and enter 0 for the bearing height

or

set the roof layer height equal to the floor height for that story and enter the plate height into the bearing height field.

I find that I often have situations with multiple plate heights in a given floor and it's easier on my little brain to use the second method.

But I've done several projects the other way. When using stories to their potential it's pretty cool.

Okay, that does help. I've put the roof on its own layer and I have put it on the same layer as floor below. But I think I prefer that it have its own layer. Whe you have different plate heights does VW pick that info up ?

[Guest Wes Gardner]

I typically recommend roofs be placed on their own layer and that layer's "Z" be the plate height of most of the roofs. You will need to adjust for additional plate heights.

Changing the subject again - if you flip the bathroom plan, the fittings will back on to a non-bedroom wall, so there will be less plumbing/drainage noise in the middle bedroom.

Thanks all for the suggestions.

Always appreciated.
