Roof and rafter

[Anonymous]

Hi,

Can someone explain how to cut out the roof this hole? (the second roof section)
Eaves and roof at the ends do not come insulation, how to solve it?
Eaves end is this rafters like in picture. how it's made?
I hope anybody could understand what I thinking.

Best regards,
Jaano

Janno,

You can use SEO with a slab deep enough to subtract all of the roof you want. You will want to make it wide enough to allow your walls to come through. Just subtract the roof from the slab with SEO.

On the rafter I would create the shape of the rafter tail from the outside of the wall face with a custom Profile with the shape you want and place on the end of each rafter that has insulation.

I hope this is clear. There are Youtube videos on using the Profile tool if you are not sure.

Cheers,

The way you model anything in ArchiCAD depends very much on what you need it for.

I almost always model the roof sheathing as a single element rather than as a Complex Profile for Composite.

How to cut out the roof where another roof meets it perpendicular?
Stretch some new nodes from the edge of the roof you want to cut, to about where the intersect is going to be, Select one roof and then use Ctrl-Click on the edge of the other roof to make the roofs intersect in the correct place.
You will find many uses for using roofs and Ctrl-Click to make the intersect.
I use roofs this way as SEO's in my excavation/site terrain models. I model soffits as roofs with 0 slope, sidewalks, garage slabs, etc... lots of things. Ctrl-Click with things modeled as roofs is an important ArchiCAD skill to learn. That is how you make the cutout in the roof I think you are after.

I could post a little video clip if you would find it useful. ?

I would like to see the Ctrl + click intersection, I have never made it before, or if you can point me to any GS video that shows this,
Thanks!

not much of a tutorial but it shows the fundamental idea.

Stretch a node/nodes (or new nodes) from the edge of the roof about where you want the roof to be cut with an intersecting roof.

Select the stationary roof, press Ctrl and Click on the edge of the roof you want to intersect with it. A little practice and this is a very useful function.

Don't forget that the CTRL-click method for joining roofs only works with single roof planes and not with a multi-plane roof (you can convert these to single planes).
With multi-plane roofs you must 'Connect > trim to roof' or simply edit as if it was a polygon.

Cool! Thanks

Single plane roofs merged together are more versatile and should achieve this a bit easier than multiplane roofs, in my opinion.

This area does not need insulation, how to resolve?
