<t>Hi everybody,<br/>
<br/>
<br/>
Right to the point.<br/>
<br/>
I have got a excercise for class today and we needed to make a <br/>
" modern building ".<br/>
<br/>
After a few tries i got an idee and started to work on it.<br/>
<br/>
But i don't find a way how to make a flat roof that is round ...
