Spirals
Spirals
(OP)
I was looking to make a simple 2D spiral. I needed it to be about 6 loops. I made one using points and the spline command. The spiral did not come out perfect, seemed a little uneven. Is there a command to make a perfect spiral.
Thanks
Mike

I dont think AutoCad 2000 has any spiral commands but this web link shows a pretty comprehensive tutorial on making involutes or spirals.

1. Draw a donut.
2. Slice the donut along a diameter, keep both halves.
3. Rotate the two halves in opposite directions for an equal angle, let's say 10 degrees.
4. Array the result.
Good luck!
