Angled roof ridge.

Everything is possible in Dietrich's.
If you need an angeled roof on a parallel building, you can work with short (2 cm) angeled lines, which define angle and pitch of the roof.

If the eaves are parallel to the rectangular walls and are horizontal but you want to have an angled ridge your roof faces are warped.
You also can do that with Dietrich's, with function 2-05 on roof calculation. But And you have luck because we have this function since your version 7.

Hi Thorvald,

I created 3 small building positions, to show you some roof calculations.
In pos 1 you find a rectangular building with 2 angeled edges. I made them bigger than required, the shortest length of the lines should be 2 cm. With longer lines it is easier to explain and see how it works.
Pos 1 works with the very normal roof calculation, which you probably use daily.

In pos 2, I made two roofs. I created some lines in dicam in order to have click points for roof calculation.

In pos 3 you find the same as in pos 2, only without roofs. This is for your exercise. Try to make the same roofs as I did.

The roofs in pos 2 are all made with funktion 2-03, the inclined roofs and the warped roofs.
To create the inclined roof, I turned the model to a non orthogonal view, in which I can find every 3d point (with no other point behind or too close to it). By clicking the points, the roof outlines will be drawn point by point.

At the back side, I created the same roof shape as at the front side, and moved 2 edge points to the original building edges (function 4-5-1). You can see, that the ground shape of the roof was not changed by this function, and after a recalculation, maybe the changes will be lost.
Please, try out to make the same changes with another function (2-01-4). The result will look the same, but it is no longer a temporary change.

To make the warped roof, I used the same dicam lines and click points, but on the bottom, I used the building edges at level ±0,00.
Click 4 points to create the warped outlines, and look at the status line, which explains the next step to do. After 1-3 tries, you will find out, how it works.
In my position, the front and the back roof have the same outlines, but if you put a rafter into both roofs, they will have different directions. The front one is defined to be parallel to the building, and the back rafter is rectangular to the ridge.

Please take as much time as you need, to learn roof calculation. If it lasts an hour or two, it's worth it.

Hi.

I made an additional description and a new position.
All you have to prepare, is a building with click points. No matter, if they are points, end of lines or edges of beams. In my position, I used 2 floor points at the bottom and two end points of prepared lines.
The roof shape has only 4 points.

Please, look and try again.

I am not sure if Thorvald wants a warped roof or not. We only know his tests but nothing about the base information.

- Is the building rectangular?
- Are the eaves parallel to the building?

My dear friend, everything is possible with Dietrich's. Just have a closer look at my forum avatar. It was designed in dicam.

And, of course, your brother's problem can be solved with straight, flat roof calculation.
Parallel horizontal eaves, ridge with angle/pitch, no curved/warped roof, why should that not be possible?

Here you are...

... never give up

It would be fine, if D-cad could produce elliptic lines, but it can't.
I would draw the outline shapes in an external 2d-cad, then import as dxf into DICAM, extrude, and work with it, not using the usual roof construction.

But, it would be possible as well, using roof design 2-05 (warped).
For me, it is easier to use DICAM, than forcing roof design to create those shapes.
