Roofs connexion

Anonymous — Tue, 23 May 2023 12:25:50 GMT

Hello I'm getting crazy on an issue

I can't connect 2 single pan roofs.By connecting I mean I would like those 2 pan to act together like a multiplan roof (that would let me crop wall by those 2 pan at a same time)

I've tried the solution of :
-select roof
-cmd (osX) + click on other roof

That do nothing more ...

You can find my project file there (ArchiCad 18):

You need to learn how to use Solid Element Operations, and also how to set clean up strenght of Building Materials.

Also upload you file as a .pla instead of a .pln

arthuragone,

After you did that, select both Roofs, click the common edge (the ridge) and use the Custom Edge Settings button of the Pet Palette. Then use the Set Mitred Edge button.

Then they should be able to Crop Walls properly.

Alternately, you could very easily create this using a multi-plane Roof. Draw a rectangle shaped multi-plane Roof, which will have 4 planes. Then set the two opposite planes to Gable, then set the slopes of the other remaining two planes to the desired angle values.

Hello laszlonagy, thanks for the help, I selected both roof, clicked on the common edge (ridge) and clicked on the Custom Edge setting button.
But can't find what you said next: the set mitrer edge button?

Edit: ok, I tried another couple of time and found the right ridge to click at then the button appear. 😎
Now my 2 plans have a nice joint at the ridge, but the still act "separately" and I still can't trim my wall by the entire roof ... 😞

Regarding your Alternate method, It work pretty well, but in this case, I can't find how to have one edge at an altitude (let say 5,00m) and the other edge at another height (let say 3 meters) ?

See the attached image for setting the common edge to mitred.
If it is correctly done, they should crop elements properly.

In case of multi-plane Roofs, the Pivot line (the blue line in the attached image) must always be at the same height for all Roof plane.

Thank you again laszlonagy for your time.

Ok, so I can't use a multiplan roof to achieve what I want.
Then I have to use 2 single plan roof and connect them together by the way you told me before.
But in this case how do I trim my walls by the entire roof?

I've tried it and even if I group together the 2 pans, the triming option is only active with one or another of the pan ...

Two methods:

1. In 2D or 3D select both Roofs and all Walls you wish to trim. Right-click and use the Crop to Single-plane Roof command.
This will create a non-associative cropping, which means that if you move the Roofs the cut of the Wall will not be updated based on their new position.

2. In 2D or 3D select both Roofs and all Walls you wish to trim. Right-click and use the Connect\Trim Elements to Roof/Shell command.
This will create an associative trimming, which means that if you move the Roofs the cut of the Wall will be updated based on their new position because each Roof and each trimmed Wall are associated with each other.

GENIUS !

Thanks a LOT !

Now I only have to dismiss little problems like insulation visible on top of the roof. I guess it's a question of priority of visualisation.

Was wondering if it is typical for the wall to show through the top of the roof after the trim/connect command has been executed. Would like the wall to stop at the bottom of the roof, not the top.

Any way to do this using the connect/trim command.

Thanksl

I think there is something wrong with that specific Wall-Roof connection because the Roof should trim the top of the Wall so it should not extend above the Roof once the operation is performed.
Can you try it with a newly placed Wall and a newly placed Roof? Place the away from your model so they do not accidentally interfere or intersect with any other existing elements. Does it work with those two elements?

It doesn't extend through the roof, but stops at the top of roof. The sloped top of the wall can be seen flush with the top surface of the roof. The wall is cut at the top surface of the roof rather than the bottom surface. See pic below.

This happens because the Intersection Priority value of the Wall's Building Material is higher than the Intersection Priority value of the Roof's Building Material. You should make it lower and that will solve the issue.

Gotcha. Thanks
