Chris

Can I take you up on your offer of help please mate?

I've downloaded a couple of CAD programs and none of them allow for a curve
to be drawn from a formulae - you needd to do something in their own
particular script and the free trial period would disappear before I have
chance to master it!

The formulae I need drawn is:

x^2  (squared) = 4 A Y

where x and y are the plotting co-ordinates,, and A is the focal length.
The range of y is +/- 150
A is 300

All dimensions are in mm

If you could print it off, and maybe send it to me as a picture file too
....

Cheers

Ian
