Here is the reply I got from Dr Bourke.

I had never heard of that so had a play. Cute.

I don't see how to do it also. What ones needs to be able to do is
create both the profile as a polygon and then be able to control the
path through which it is revolved. I could not find out how to do the
first and the second certainly seems like it isn't supported.

It is easy to do with a C program, see attached along with
corresponding slt file. The top of the C program has the parameters
double r0=1.0,r1=0.25;
double n1=1.0,n2=0.2;

Here are the files he sent.

supertorus.c

supertorus.stl.zip

Have fun!!
