tetto in archicad...

[matt3d]

... hello to all and good parties,

are struggling with a problem regarding the cover of a building:

In this case, I would have two adjacent buildings with a shared wall, the plants are slightly staggered, minimally but sufficient to create a roof with a complex profile.

I would need to see only one part of the cover, that is the one above one of the two buildings, being the rest even drawn. . .

in practice over my building I have a 3-phalt roof, with a triangular "front" in correspondence where there is the shared wall.

Do you have any idea how I can do that?
for now I have created the total roof (including also the rest over the adjacent building) but I do not know how to cut the useless part. . .

use archicad 11, on mac os.

thank you all,

and good holidays again!

I think I don't understand, you just want to represent a part of the roof that you made if you make some screens of both 2d and 3d with some indication maybe I can help you

Here... I hope it is clearer (...it is only an example model),

photo 1 you see the geometry of the roof, I only care about the left part;
photo 2,3,4 are the sections, in retinato the parts to be excluded;
photo 5 you see what I would like to get, of course this image I got it by doing a section, but it is not the appropriate method.

said this, I would like to know how I can make the 3-phalt roof of photo 5, of course in the 5 missing the wall and triangular front of buffering in the attic...; In view of the fact that I did it with the poly-falde command, I currently have the full roof from which I would like to remove the surplus.

but if there is the possibility to do it directly to 3 falde.... well be suggestions! :finger:

p.s.: I tried to do it with single ground command... but there's no precise work... :frown:

I think I still have little clear the final result you want to get, so at first glance, I would say:
Boolean operations
make a ceiling of the size of the roof to be eliminated and after performing the subtraction hide in a special polish this loft.
If you need a wall, where you've dissected, create walls and then cut off with the bonfires or something that you need for greater mobility, use the Boolean operation also for this.
you can probably do all this with a single boolean operation between the roof and the wall of the front, but now I have little time to study an adequate solution

 

[matt3d]

...:frown: unfortunately the subtraction between solids was one of the first things I tried. . .

And it's not going!

cmq you have centered the goal I would like to get! :finger:

Thanks the same.

make some mistakes in solid elements operations, because I did a test and it should work. by doing the Boolean operations that problem you are experiencing?

 

[matt3d]

...I have built a loft of height so as to totally incorporate the roof that I want to subtract; then I brought it to the height of the roof and with operation between solids I took the 2 elements... I used the command before, I know it...
This time, nothing happens.

I'll try again!

the important thing is that, "for archicad", I can do operation between "falde" and "solai" as you say; if you confirm... It's already a help!

Thank you again!

You can do it. Remember that for Boolean operations you must select the operator element first, then the loft, then uncheck it and select the target elements. then you have to do the simple subtraction and put the operator element in a hidden polish. after what you will have to do the wall and choose between "cut with the bonfires" or do a second Boolean operation

...proved and re-proven!
Nothing!

I also opened a new project, made a 4-phalt roof and the sole operator.. (in case there was a bug in my project..), but also in this case, the only thing I can notice is the visual change of the polygonal of the points that unites the edges of the solid: but when I put the operator in the hidden gloss, the roof appears complete!
I can't see if I have to set a parameter somewhere... because your directions are clear and simple, so I do not see where I can wrong;
I also did a subtraction between floors, and in fact it works everything (even without putting the operator in the hidden polish).

thank you anyway!
