I had the same problem with wheels, you need to rotate the piece where it is
declared, ie:
#declare _3649_dot_dat = #if (QUAL = 0) box { <-52.99,-52.99,-10>,
<52.99,52.99,10> } #else union {
object { axlehol5_dot_dat matrix <0,1,0,0,0,20,1,0,0,0,0,-10> }
triangle { <45,0,6>, <44.45,7.04,6>, <44.45,7.04,-6> }
*lots more triangles here, with the rest orf the part I snipped*
//
}
rotate 30*z*clock // the degrees to rotate, by the axis to use then telling
it to use the clock }
Here's the scene file I used, and the animation it created:
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=10723
its a microsoft video clip of 258 kb.it should play in microsoft video
player.

P.s. if you need any more help feel free to e-mail me. :-)
BTW here's the software I use to make the bmps into avi movies, its

| (...) This has the side-effect that all uses of 3649 will rotate the same. It's better to do like Bram suggested: object { _3649_dot_dat rotate <0, 0, clock*30> matrix <0,1,0,-1,0,0,0,0,1,0,-59,-20> #if (version >= 3.1) material #else texture #end { (...) (22 years ago, 23-Jan-02, to lugnet.cad)
