3D section cut?

I do not understand what you mean. Can you show us a picture?
We can do every cut and we can show it in OpenGL and we even cad do it in OpenGL.

Hi Thorvald,

do you mean a section like this?
Go to the wall construction, and press the OpenGL button. You will see a section as thick as the wall in OpenGL.
If you need the section at an other place, you can make a temporary wall in any direction and with any thickness (f.e. half the building), and enjoy the result.
The temp. wall should be under the building, with texture "NOTEX", then it doesn't intersect with other walls and it is unvisible in OpenGL.

With wall construction 1-7-1 you can define, which elements are visible in this section.

next step:

If you need the OpenGL section in a drawing, you can make an orthogonal printscreen, and use it as background picture. You should cut the picture exactly at the first and the last rafter pixel, then it is quite easy to calculate the correct scale.

It seems so that I did not understand correctly the word section cut. :oops:

It was not my idea, but I remember how to get it.

You can show vertical or horizontal sections with wall or ceiling construction.
It is also possible to show angeled views, but you cannot exactly define the cutting slice.

- view the model in the normal OpenGL (not in construction mode)
- walk into the middle of the building
- rightclick to change the options to "parallel view"
- when you turn around now, you will see the section that you need
- it will take some experience to find out the correct view place.

I think, you already found the best way to make this kind of pictures.
