Has anyone else had this experience?  I'm using PovWin 3.02 and I was 
trying to scale a cylinder into something resembling a plank only to have 
it translated rather than scaled.

Something like cylinder{<0,0,0>,<1,0,0>.......scale<1,1,10>.... will push 
it back 10 units in a positive z direction.

Is scale not supposed to be used in a blob?  I do appreciate the program 
very much, I just wish more shapes could be used within blobs.  Glass 
blobs are interesting.

Hi !
The order of tranforms matter. If everything is around the origin, you can do
what you
want, but if you translated something away from <0,0,0> and then rotate and
scale I
guess you get <the wrong> other results.
