chimney

[Anonymous]

Hello!
I am using Archicad 9 but i am beginner so please dont be offended with this request.
I am drawing a wall. Lets say it's THICKNESS is 50 cm.
Now I want to make a chimneys in it (different size).
I want them to be seen on a plan view and section view also, that I will be able to print those two.
Best regards
Mar

Mar,
If you mean that you want to make a flue in a 50 cm thick wall
then draw two pieces of 50 cm wall with a gap between them
the width of your flue. Then draw two walls with a thickness
of say 10 cm, or what ever you want the flue wall thickness to be,
flush with the 50 cm walls that fills the gap on both sides.
Switch the sides of the reference lines of the thinner walls
until you get all the walls to clean-up in 3D. In 2D one of
the thin walls will not clean up with the thick walls
so you will have to draw some fills with the same fill
pattern as your walls to mask the joints. Remember
to bring the fills to the front.

Thank you!
This seems so obvious now, but from the other hand very frustrating that there is no other way to make it.
I thought that there could be something like a tool for that!
Thanks again,
Regards

You'd think this could be accomplished using a polygonal wall by putting a hole in it, just like we do with fills, but that'd be too easy! I thought we might even be able to use that method to get a U shaped wall and then use a single wall to fill in the top side of the flue. That would avoid needing to use any fills, but then the straight wall doesn't show up in 3D!

Cheers,
Link.

Both of you guys showed just a one flue.
We all know that there are many flues in wall with chimney.
How that should be done?
I guess the same as Peter described it, but then still there is a huge problem with fills.
I think this should be resolved in a next versions of ArchiCad

Yes Link, it always puzzled me why a polygonal wall could not be made
to have a hole in it. I have even tried to make a "C" shaped
polygonal wall then close the gap but then the hole disappears.

I'd probably use a slab depending on the situation. You can put as many holes as you like in a slab.

I haven't tried it but could you use a composite for the flue, with two outer skins and a cavity, that is the same total width as the wall adjacent. If composite's skins are set to same priority as the wall (with a different priority for the cavity) do they clean up?

Or you could use the polywall and then use a column with an empty fill to cut the holes. Columns cut walls by default. Hide the layer the col in on in section and you only see the wall and the cut.
Just another approach!!

Me too mate. I have submitted this as a bug to GS.
