My spreadsheet gives me an error when I try to give it 1 for the major
radius, however, If I give it 1.000001(or something like that) it gives me a
workable file. The file name is of course t04o0000.dat (.9999 would have
rounded to 1.0000).
Some time ago I spent some time playing with torus files that broke the
rules as we established them, I made the part numbers r04_####.dat.
I was playing with trying to make a POV subsitutable part for the 6909
window piece Mark Kennedy was working on. ex:
1 16 0 40 0 20 0 0 0 -20 0 0 0 20 48\r04o0200.dat
1 16 0 40 0 20 0 0 0 -20 0 0 0 20 48\r04o0180.dat
In this form, the part number in discussion(1mr:1tr) would be r04o0100.dat
(it seems I must have moved the invisible "decimal" point over).
another ex: 0.4mr:1tr would be r04_0250.dat
So far I have only adapted the ro4 format to the "high resolution" sheet.
(Food for thought) :-)

I have the p/t04o0000.dat and p/48/r04o0100.dat files ready for posting if
you want either one. LMK

| (...) Could we go with t04x0100.dat instead? The 't' would be to keep all the torus files together. Only the 'outer' primitives would be made for these >1:1 toruses, right? (I'm having a hard time figuring out what the 'inner' parts would be good (...) (22 years ago, 12-Jun-02, to lugnet.cad.dat.parts.primitives)

| (...) Yes, I can. If you have taken a look at the rough mockups I posted in CAD/PARTS, you will see a reference to a subfile called "fettorus.dat". This is in fact the primitive in question (although scaled up by a factor of 8), and it is used as (...) (22 years ago, 12-Jun-02, to lugnet.cad.dat.parts.primitives)
