Hi,

is there a way to align an object to a predifined vector?

For example, how do I rotate the object

cone{<0,0,0>,1 <1,0,0>,1}

to align with the vector <1,1,1> (i.e. I should have drawn the cone with 
<0,0,0>,1 <1,1,1>,1).

The 'rotate' command doesn't help me much.

Thanks in advance,
Sebastiaan

Look at Point_At_Trans() and Reorient_Trans() in transforms.inc. There 
is additional documentation in the manual.
