Hi everybody, I want to ask what is the easiest way to make curtain wall like one on the picture below. The problem for me is because the wall is inclined for about 10 degrees (but thats not matter how much degrees, it is important that it is inclined) and i want divisions also inclined in plane of that wall. I scanned my sketch so i hope that you will understand my question.
PS. I must admit that i never used curtain wall tool before, but i used wall tool with columns and beams.

You should create the Curtain Wall in Section using the Boundary method.
You draw the boundary in Section and that's it.
Just make sure that you model the full surface as if it was standing upright. You will do the 10 percent slant later.

In 3D you can edit the Curtain Wall and you can set the primary and secondary grid of the Curtain Wall to be at an angle other than 90 degrees.
Similarly you can move the whole grid to position it to the exact desired location.

Notice that in the little palette in the upper left corner of the 3D Window I switched on Scheme and turned off Frame and Panel to be able to easier manipulate the Scheme of the Curtain Wall.

Now that the Primary Grid is at the correct orientation, go to the Section and measure the needed angle between the Primary and Secondary Grid.

Here I said the Secondary Grid should be parallel to the upper edge of the Curtain Wall.

Now I go back to editing the Curtain Wall in 3D.
I use the Move Grid command to move a grid intersection point to the upper left corner of the boundary.

No I go to the System Settings and set the exact distances between the Primary and Secondary Frame.

Finally, I go to the 3D Window, select the Curtain Wall and use the Design\Curtain Wall\Curtain Wall Free Rotate command to rotate it 10 degrees.
First you have to define the Rotation axis with 2 clicks, then the rotation angle with another 2 clicks.

On your sketch it looks like your Grids are not even parallel, like none of your Grid Lines are parallel.
In such a case you would have to draw the Frames one by one.

Thanks Laszlo, really good tutorial. I understood the whole procedure, just i have the problem at the start. I don't know how to change default scheme, and put divisions the way i want, not to change and delete the panels which came with default scheme.

Use the Frame Tool when editing the Curtain Wall in 3D.
Click anywhere on the boundary polygon of the Curtain Wall and it will start drawing a new Frame.
Click again anywhere on the boundary polygon of the Curtain Wall and a new Frame will be drawn between the two given points.
This way you can draw as many new Frames as needed.
