Hi. How can we create this roof ? Is there any way to create it.
Please explain me.

Create each roof plane with the desired slope and direction using the Single-plane Roof geometry option. Then connect the planes using the intersect command. In the Help files see: Elements of the Virtual Building > Construction Elements > Roofs > Editing Roofs > Intersect Single-plane Roofs.

You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.

Thank you for your help. I try this but I dont create this model.
Can you create this model with a video. ? I dont find a formula "how can i do this.

Take a look at the you tube channel for Archicad.
look for videos on the roof tool.

There's an object called "Mesh_3d" which you could possibly use if you don't want the intersections between the roof planes created when using the Single Plane Roof tool. Set the thickness and the node grid to 9x3 then in the 3d window, stretch the nodes to their relevant position.

It is quite easy to do in 3D.
Model 3 columns for the 3 apex heights for the first roof section.
Use a zero thickness polygon single roof plane and click on points 1, 2 & 3 to define the roof slope.
Then click points 1, 2, 3 and 1 again to define the shape of the roof surface.

Now do the same for 4, 5 and 6 - once to define the roof pitch and again to define the shape of the roof surface (click points 4, 5, 6, and 4 again to define the surface).
I used guidelines to get the position of point 4 but you could place another column.

Now you have these 2 planes, you can mirror copies to get the rest.

Now if you want you can select them all ad add a thickness.
For some reason it does not work well if you set the thickness before defining the roofs.

Thank you for your help. But its too hard for me Can you explain this with a video please ?

I can try but I will have to do it a little later.
It really won't tell you any more than explained.

Each of your roof planes have 3 points.
You need to establish the heights of these points in 3D - hence the columns.
Now all you do is set the roof tool as shown in the image and click on the first 3 points (top centre of the columns) to determine the roof plane slope.
Click the same 3 points again to place the roof plane.
Do the same for the next 3 points (4, 5 & 6).
Now you have all you need - just a matter of mirroring copies to get the complete roof.

I will look at making a video later today, unless you solve it in the mean time.
Or somebody else beats me to it.

Sorry but I am having trouble recording a video.
My first attempt did not record the steps in 3D at all - just the start and then the finished product.
My latest attempt is a bit jumpy and does not clearly show the steps - but if you really want I can e-mail it to you (I have your address already but wont send it till you say so).
I won't post it here because it is really not good enough.

I did realise that when placing the roof you click the first 3 points to define the roof slope then I said click the same 3 points to place the roof - you actually have to click the 1st point again (for a 3rd time) to close the polygon.
So it is point 1, 2, 3 then 1, 2, 3, and 1 again.

I have amended the original post.

Barry.

Also look in the reference manual in the HELP menu.
