Hi Arjo :
Seriously ? 100 times without any instructions but 15 times with
your instructions , just to make sure I wasn't missing something .

No , but the mesh was no longer smooth and round and had bad
artifacting near the tail , so I just stopped there .

Yes , I think so .

Hmmm , well , twice , thrice ... in & out of the manual ...

Yes , the concept is fairly easy to understand , I think . The
difficulty comes in having to understand all the different kinds
of magnets , all the different options available .
In trying tocreate new magnets you have to know which type of
magnet to create these new magnets from , and where to create
them , and should the new magnets be sharp or free points ,
yes , but should the edges be smooth , and the faces should be
subdivided , but these must be free , unless you need more stru-
cture there , then not ...
It goes on and on and on with SDS .

Yes , maybe , if you start with all magnets strong and everything
sharp or free , but when we begin with SDS primitives ,everything
is smooth and weak and it's like working with soggy putty .

I have nothing that works as you describe . I hit the '1' key and
nothing happens . However , if I use 'Scale 1D' tool , I then have
to use some kind of odd parallel lines , and then some kind of a box
appears and _THEN_ it scales the shape ... but nothing as you desc-
ribe (just click , click click {I wish it were !])

I will do as I always do , build it from nurbs curves , one at a
time if I have to ... whatever ... one way or another , with several
trips to the strip bar in between , most likely ... somewhere quiet
where there are no brilliant S/W scientists sitting in the corner
designing their latest form of torture devices .
Thanks for your replies .
